As explained in the Talmud, there is a tradition that the Sun was created in its vernal equinox position at the beginning of the springtime Jewish lunar month of Nissan.Bavli Rosh Hashanah 10b The sages of the Talmud settled disputes over the halachic definition of the vernal equinox by establishing it on March 25 of the Julian calendar. Because both the Julian calendar and Jewish tradition define a solar year as exactly 365.25 days, the halachic vernal equinox historically fell out on March 25 every year. This halachic equinox now falls about 17 days after the true equinox, with the error increasing by about 3/4 of a day per century.
Since the Council of Nicaea in 325, the Western Church had required that Easter be celebrated on the Sunday on or after the full moon following March 21, which at that time corresponded indeed to the vernal equinox.

Roger B. Bate, Donald D. Mueller, Jerry E. White, "Fundamentals of Astrodynamics," Dover, 1971, New York, pp. 53-57. The Sun lies in the direction of the vernal equinox around 21 March. The fundamental plane for ECI frames is usually either the equatorial plane or the ecliptic. The location of an object in space can be defined in terms of right ascension and declination which are measured from the vernal equinox and the celestial equator.
Astrologers use many ways to divide the Great Year into twelve astrological ages. There are two popular methods. One method is to divide the Great Year into twelve astrological ages of approximately equal lengths of around 2160 years per age based on the vernal equinox moving through the sidereal zodiac. Another method is to significantly vary the duration of each astrological age based on the passage of the vernal equinox measured against the actual zodiacal constellations.

According to the Iran Labor Code, Friday is the weekly day of rest.
The angle between the Earth's equatorial plane and the ecliptic, ε, is called the obliquity of the ecliptic and ε ≈ 23.4°. An equinox occurs when the earth is at a position in its orbit such that a vector from the earth toward the sun points to where the ecliptic intersects the celestial equator. The equinox which occurs near the first day of spring (with respect to the North hemisphere) is called the vernal equinox. The vernal equinox can be used as a principal direction for ECI frames.
As seen from above the Earth's north pole, a star's local hour angle (LHA) for an observer near New York. Also depicted are the star's right ascension and Greenwich hour angle (GHA), the local mean sidereal time (LMST) and Greenwich mean sidereal time (GMST). The symbol ʏ identifies the vernal equinox direction. The right ascension symbol , (lower case "alpha", abbreviated RA) measures the angular distance of an object eastward along the celestial equator from the vernal equinox to the hour circle passing through the object.

The heliacal rising constellation at the vernal equinox is based on the last zodiacal constellation rising above the Eastern Horizon just before dawn and before the light of the approaching Sun obliterates the stars on the eastern horizon. Currently at the vernal equinox the constellation of Aquarius has been the heliacal rising constellation for some centuries. The stars disappear about one hour before dawn depending upon magnitude, latitude, and date. This one hour represents approximately 15 degrees difference compared to the contemporary method based on the position of the Sun amongst the zodiacal constellations.
Taurus marked the point of vernal (spring) equinox in the Chalcolithic and the Early Bronze Age, from about 4000 BC to 1700 BC, after which it moved into the neighboring constellation Aries. The Pleiades were closest to the Sun at vernal equinox around the 23rd century BC. In Babylonian astronomy, the constellation was listed in the MUL.APIN as , "The Bull of Heaven". Although it has been claimed that "when the Babylonians first set up their zodiac, the vernal equinox lay in Taurus," there is a claim that the MUL.

If, instead of measuring from and along the horizon, the angles are measured from and along the celestial equator, the angles are called right ascension if referenced to the Vernal Equinox, or hour angle if referenced to the celestial meridian.
One of the primary reasons that the church was so supportive of astronomical research was that the church needed astronomers to assist in resolving issues with the calendar—specifically in establishing a date for Easter. In 325 A.D., the Catholic theologians comprising the Council of Nicaea, set the date of Easter as the first Sunday after the first full moon of the vernal equinox where the vernal equinox was the point of equal daylight and darkness.Öberg, Karin I. (2009). Complex processes in simple ices - Laboratory and observational studies of gas-grain interactions during star formation (Ph.D.).
The reference frame is relatively stationary, aligned with the vernal equinox. A rectangular variant of ecliptic coordinates is often used in orbital calculations and simulations. It has its origin at the center of the Sun (or at the barycenter of the Solar System), its fundamental plane on the ecliptic plane, and the -axis toward the vernal equinox. The coordinates have a right-handed convention, that is, if one extends their right thumb upward, it simulates the -axis, their extended index finger the -axis, and the curl of the other fingers points generally in the direction of the -axis.

On that day, the Fraumünster bell, for the first time in the year, tolled to mark the end of working hours at 6 p.m. (historically the time of sunset on vernal equinox). The holiday was moved to the third Monday of April in 1952.
Paul favored resetting the date of the vernal equinox to March 10 rather than eliminating days to correct the drift but the changes were not made. Copernicus, a contemporary of Paul, attributed the failure to inaccuracies in measurements of the sun and moon and he focused his attention on collecting more accurate data. Accurate data about the vernal equinox required a large, dark space like a cathedral to measure a meridian line. A hole was cut into the roof of a cathedral and using a rod or line in the floor, they measured the time it took for a noon time image of the sun to return to the same place.
Hamal's orientation with relation to the Earth's orbit around the Sun gives it a certain importance not apparent from its modest brightness. Between 2000 and 100 BCE, the apparent path of the Sun through the Earth's sky placed it in Aries at the northern vernal equinox, the point in time marking the start of spring in the Northern Hemisphere. This is why most astrology columns in modern newspapers begin with Aries. While the vernal equinox has moved to Pisces since then due to precession of the equinoxes, Hamal has remained in mind as a bright star near what was apparently an important place when people first studied the night sky.
The two planets "exchange angular momentum in a 5:1 mean motion resonance". This planet was discovered on the vernal equinox of 2008 by analyzing perturbations with the inner planet HD 17156 b. The paper was submitted to Astrophysical Journal Letters 20 March and revised 14 June.
Marzanna is a Slavic goddess of death, associated with winter. The rite involves burning a female straw effigy or drowning it in a river, or both. It is a folk custom in Poland, Slovakia and the Czech Republic, taking place on the day of the vernal equinox.
Because the Earth takes approximately 365.24 days to go around the Sun, the precise time of the equinox is not the same each year, and generally will occur about six hours later from one year to the next until reset by a leap year. February 29 of a leap year causes that year's vernal equinox to fall about eighteen hours earlier—according to the calendar—compared with the previous year. From 1800 to 2050 inclusive the vernal equinox date has (or will) range(d) from March 19 at 22:34 UT1 in 2048 to March 21 at 19:15 UT1 in 1903. Under the sidereal zodiac, the sun currently transits Aries from April 15 to 14 May (approximately).
Traditionally this 25,800 year-long cycle is calibrated, for the purposes of determining astrological ages, by the location of the sun in one of the twelve zodiac constellations at the vernal equinox, which corresponds to the moment the sun crosses the celestial equator, marking the start of spring in the Northern Hemisphere each year. Roughly every 2,150 years the sun's position at the time of the vernal equinox will have moved into a new zodiacal constellation. However the 12 zodiacal constellations, as defined in modern astronomy, are not uniform in size, leading some astrologers to believe that the corresponding ages should also vary in duration. This however is a contentious issue among astrologers.
Earth-centered ecliptic coordinates as seen from outside the celestial sphere. Ecliptic longitude (red) is measured along the ecliptic from the vernal equinox. Ecliptic latitude (yellow) is measured perpendicular to the ecliptic. A full globe is shown here, although high-latitude coordinates are seldom seen except for certain comets and asteroids.
Heliocentric ecliptic coordinates. The origin is the Sun's center, the plane of reference is the ecliptic plane, and the primary direction (the -axis) is the vernal equinox. A right-handed rule specifies a -axis 90° to the west on the fundamental plane. The -axis points toward the north ecliptic pole.
By the 16th century, the date of the vernal equinox on the Julian calendar had receded from March 25 to March 11. The Council of Trent in 1562 authorized the pope to deal with calendar reform. The resulting Gregorian calendar is the internationally accepted civil calendar used throughout the world today.Introduction to Calendars.
Assyrian child dressed in traditional clothes The Assyrian dialects Assyrian culture is largely influenced by Christianity. There are many Assyrian customs that are common in other Middle Eastern cultures. Main festivals occur during religious holidays such as Easter and Christmas. There are also secular holidays such as Kha b-Nisan (vernal equinox).
Structure 6 (or Structure VI) is on the west side of the Central Plaza and, together with Structures 4a, 4b and 4c, forms an E-Group astronomical complex. In 1989 observations verified that on March 21, the vernal equinox, the sun rose behind Structure 4b as seen from Structure 6.Folan et al.
The Gregorian calendar is a reformed version of the Julian calendar. By the time of the reform in 1582, the date of the vernal equinox had shifted about 10 days, from about March 21 at the time of the First Council of Nicaea in 325, to about March 11. According to , the real motivation for reform was not primarily a matter of getting agricultural cycles back to where they had once been in the seasonal cycle; the primary concern of Christians was the correct observance of Easter. The rules used to compute the date of Easter used a conventional date for the vernal equinox (March 21), and it was considered important to keep March 21 close to the actual equinox .
This epoch causes the roughly 30 Indian calendar years to begin 23–28 days after the modern vernal equinox. The vernal equinox of the Surya Siddhanta librated 27° in both directions from the sidereal epoch. Thus the equinox moved 54° in one direction and then back 54° in the other direction. This cycle took 7200 years to complete at a rate of 54″/year. The equinox coincided with the epoch at the beginning of the Kaliyuga in −3101 and again 3600 years later in 499. The direction changed from prograde to retrograde midway between these years at −1301 when it reached its maximum deviation of 27°, and would have remained retrograde, the same direction as modern precession, for 3600 years until 2299.
In astrology, an astrological age has usually been defined by the constellation or superimposed sidereal zodiac in which the Sun actually appears at the vernal equinox. This is the method that Hipparchus appears to have applied around 127 BC when he calculated precession. Since each sign of the zodiac is composed of 30 degrees, each astrological age might be thought to last about 72 (years) × 30 (degrees) = about 2160 years. This means the Sun crosses the equator at the vernal equinox moving backwards against the fixed stars from one year to the next at the rate of one degree in seventy-two years, one constellation (on average) in about 2160 years, and the whole twelve signs in about 25,920 years, sometimes called a Platonic Year.
Ayyám-i-Há refers to a period of intercalary days in the Baháʼí calendar, when Baháʼís celebrate the Festival of Ayyám-i-Há. The four or five days of this period are inserted between the last two months of the calendar (Mulk and ʻAláʼ).According to the definition of intercalary days in the Oxford Companion to the Year four of the five days are "epagomenal days" added to make the number of a calendar's days equal to the number of days in a year, and only the fifth day of Ayyám-i-Há is an intercalary day. The length of Ayyám-i-Há varies according to the timing of the following vernal equinox so that the next year always starts on the vernal equinox.
Symbol for Pisces: 33px While the March equinox occurs in Pisces; At the end of the Age of Pisces, the vernal equinox point will have moved into the constellation of Aquarius, thus beginning the Age of Aquarius. Various astrologers make widely varying claims about when the age will end or whether it has ended already.
His son was born on March 20, at the time of the vernal equinox. Napoleon is seen as ending the French Revolution through being crowned Emperor. The word revolution comes from revolutus, "applied to a curled-up serpent" (Sonnenfeld p 35). This could be seen as analogous to Apollo's slaying of Python, which liberated the Greeks from terror.
Since Leo begins 120° from the vernal equinox, the longitude in modern form is .; numerous examples of this notation appear throughout the book. In China, ecliptic longitude is measured using 24 Solar terms, each of 15° longitude, and are used by Chinese lunisolar calendars to stay synchronized with the seasons, which is crucial for agrarian societies.
The longitudes of the houses (bhava-sphutas), oblique ascensions (rasimanas) and other calculations are all computed for Sayana Rasis or signs, from these the Ayanamsa is subtracted and the Nirayana bhavas, etc., are obtained. The Ayanamsa is the distance between the Hindu first point of the Zodiac i.e. Zero degree Aries, and the Vernal Equinox, measured at an epoch.
1, p. 51 While he interpreted the beginning of the year at the vernal equinox, Arthur Anthony Macdonell 1917 stated that the twelve intercalary days "in all probability" were inserted at the winter solstice.Dates and Eras in Ancient Indian History Vol.1, p.76, Note 86, referring to A.A. Macdonell A History of Sanscrit Literature, p.
Thus the two zodiacs would be aligned only once every 26,000 years. They were aligned about 2,000 years ago when the zodiac was originally established. This phenomenon gives us the conceptual basis for the Age of Aquarius, whose "dawning" coincides with the movement of the vernal equinox across the cusp from Pisces to Aquarius in the star background.
Before that time, the Baháʼí calendar was synchronized to the Gregorian calendar by starting the year at sunset on March 20, regardless of when the vernal equinox technically occurs, meaning that the extra day of a leap year occurred simultaneously in both calendars. The intercalary days always stretched from 26 February to 1 March, automatically including the Gregorian leap day so that there were 4 intercalary days in a regular year, and 5 in a Gregorian leap year. The Universal House of Justice selected Tehran, the birthplace of Baháʼu'lláh, as the location at which the time and date of the vernal equinox is to be determined according to astronomical tables from reliable sources.For calculating the dates, data provided by HM Nautical Almanac Office in the United Kingdom is used by the Baháʼí World Centre.
There are two camps of thought among western astrologers about the "starting point", 0 degrees Aries, in the zodiac. Sidereal astrology uses a fixed starting point in the background of stars, while tropical astrology, used by the majority of Western astrologers, chooses as a starting point the position of the Sun against the background of stars at the Northern hemisphere vernal equinox (i.e. when the Sun position against the heavens crosses over from the southern hemisphere to the northern hemisphere) each year. As the Earth spins on its axis, it "wobbles" like a top, causing the vernal equinox to move gradually backwards against the star background, (a phenomenon known as the Precession of the equinoxes) at a rate of about 30 degrees (one Zodiacal sign length) every 2,160 years.
Each sign contained 30° of celestial longitude, thus creating the first known celestial coordinate system. According to calculations by modern astrophysics, the zodiac was introduced between 409-398 BC and probably within a very few years of 401 BC. Unlike modern astronomers, who place the beginning of the sign of Aries at the place of the Sun at the vernal equinox, Babylonian astronomers fixed the zodiac in relation to stars, placing the beginning of Cancer at the "Rear Twin Star" (β Geminorum) and the beginning of Aquarius at the "Rear Star of the Goat-Fish" (δ Capricorni). Due to the precession of the equinoxes, the time of year the Sun is in a given constellation has changed since Babylonian times, the point of vernal equinox has moved from Aries into Pisces.
Sea Mither is a spirit of summer days that quells the turbulent sea waters around the northern isles of Scotland. Shetland islanders, particularly fishermen, seek her protection from the Devil. Control of the seas is maintained by Teran, the spirit of winter, until Sea Mither arrives around the time of the vernal equinox in mid-March. Both spirits are invisible to humans.
The location of stars, planets, and other similarly distant objects is usually expressed in the following parameters, one for each of the three spatial dimensions: their declination, right ascension (epoch-fixed hour angle), and distance. These are as located at the vernal equinox for the epoch (e.g. J2000) stated. A meridian on the celestial sphere matches an hour circle at any time.
This is commonly seen in astronomical clocks of the period. The small golden star shows the position of the vernal equinox, and sidereal time can be read on the scale with golden Roman numerals. The zodiac is on the 366-tooth gear inside the machine. This gear is connected to the sun gear and the moon gear by a 24-tooth gear.
In order to bring the calendar back to its proper place, Augustus was obliged to suspend intercalation for one or two decades. The revised calendar remained slightly longer than the solar year; by the 16th century the date of Easter had shifted so far away from the vernal equinox that Pope Gregory XIII ordered the calendar's adjustment, resulting in the Gregorian calendar.
Kumo Kaze, as it is sometimes called, had its premier broadcast on March 21, 1990 during the vernal equinox national holiday, and was shown in an unprecedented commercial-free presentation. The movie was released on Region 2 DVD in 2002. The film is currently licensed in North America by Discotek Media who subsequently released it on DVD and Blu-ray.
The Julian calendar used in Christendom until the 16th century added a leap day every four years; but this rule adds too many days (roughly three every 400 years), making the equinoxes and solstices shift gradually to earlier dates. By the 16th century the vernal equinox had drifted to March 11, so the Gregorian calendar was introduced both to shift it back by omitting several days, and to reduce the number of leap years via the aforementioned century rule to keep the equinoxes more or less fixed and the date of Easter consistently close to the vernal equinox. Leap days can present a particular problem in computing known as the leap year bug when February 29 is not handled correctly in logic that accepts or manipulates dates. For example, this has happened with ATMs and Microsoft's cloud system Azure.
Number 3 Queensborough Terrace, Bayswater: headquarters of the Society of Inner Light from 1924 At the vernal equinox of 1930, Fortune declared that—with the 'Lesser Mysteries' and three degree system now properly established—she wanted to turn away from public work and focus on personal spiritual development. At the vernal equinox of 1931, Fortune stepped down as leader of the Fraternity, with Loveday being appointed Magus of the Lodge in her place. During the 1930s, Fortune's emphasis moved away from mediumship and towards ritual, while at the same time other Fraternity members embraced mediumship in order to channel the messages of the Masters. In late 1931, Fortune began mooting the idea of the construction of a permanent base, or Sanctuary, at the Chalice Orchard, and despite the economic obstacles of the Great Depression was able to raise sufficient funds.
Eyes of the Storm is the third book in the Bone series. It collects issues 12-19 of Jeff Smith's Bone comic book series along with 5 previously unpublished story pages and 9 new illustrations. It marks the conclusion of the first part of the saga, titled "Vernal Equinox". The book was first published by Cartoon Books in its original black-and-white form in 1996.
Phillip Pfatteicher, Festivals and Commemorations, p. 11. Because Easter varies in date each year based on the vernal equinox and the phases of the moon, it is called a moveable feast (see: Computus). Dates affected by placement of Easter include Ash Wednesday and the start of Lent, the start of Easter itself, Pentecost, and Holy Trinity.Phillip Pfatteicher, Lutheran Book of Worship: Manual on the Liturgy, p. 22.
Its traditional name is derived from "sharatayn", the Arabic word for "the two signs", referring to both Beta and Gamma Arietis in their position as heralds of the vernal equinox. The two stars were known to the Bedouin as "qarna al-hamal", "horns of the ram". It is 59 light-years from Earth. It has a luminosity of and its absolute magnitude is 2.1.
The exact timing of this shift is difficult to determine due to the lack of images of Aries or other ram figures. In ancient Egyptian astronomy, Aries was associated with the god Amon-Ra, who was depicted as a man with a ram's head and represented fertility and creativity. Because it was the location of the vernal equinox, it was called the "Indicator of the Reborn Sun".
It was strongly associated with Mars, both the planet and the god. It was considered to govern Western Europe and Syria, and to indicate a strong temper in a person. The First Point of Aries, the location of the vernal equinox, is named for the constellation. This is because the Sun crossed the celestial equator from south to north in Aries more than two millennia ago.
Note that, having ordered intercalations in 630 and 631 (proved by reports of the interval between the birth and death of Ibrahim and a solar eclipse on the morning of his death) the Nasīʾ did not order another one in 632 - Muhammad took advantage of the hiatus by stripping them of their power. At that time the vernal equinox was occurring about 19 March.
The equinoxes and solstices are different as well: for the northern hemisphere, vernal equinox is in Ophiuchus (compared to Pisces on Earth), summer solstice is at the border of Aquarius and Pisces, autumnal equinox is in Taurus, and winter solstice is in Virgo. As on Earth, precession will cause the solstices and equinoxes to cycle through the zodiac constellations over thousands and tens of thousands of years.
The Kerala New Year (Malayalam Calendar) used to be on the day of vernal equinox, i.e., the day when the sun is considered to move from the southern to the northern hemisphere. The day now falls in the first Malayalam month of Chingham according to the Kollam Era. Till the modern Malayalam calendar Kollam Era Indian Journal on History of Sciences 1996, pg 94.
In 1911 the jalali calendar became the official national calendar of Persia. In 1925 this calendar was simplified and the names of the months were modernised. 1 Farvardin is the day whose midnight start is nearest to the instant of vernal equinox. The first six months have 31 days, the next five thirty, and the twelfth has 29 days and 30 in leap years.
The festival is subdivided into "Maghar Domahi" (mid January), "Baihagar or Baishakh Domahi" (mid April) and "Katir or Kartika Domahi" (mid October). Astronomically Baihagar Domahi is associated Vernal equinox, Kati Domahi with Autumnal equinox and Maghar Domahi with Winter solstice. Greater importance is attached to the winter festival than to the spring festival. But the third festival, held in autumn, is not always considered as another Domahi.
The sign of Taurus is associated with several myths and bull worship from several ancient cultures. It was the first sign of the zodiac established among the Mesopotamians, who called it "The Great Bull of Heaven," as it was the constellation through which the Sun rose on the vernal equinox at that time, that is the Early Bronze Age, from about 4000 BC to 1700 BC.
The Iranian civil calendar of 1925 reinstated Zoroastrian month-name conventions and hence also has Khordad as the third month of the year, beginning at May 22 (21. in leap years). This calendar is thus the one with which western astrology is most accurately corresponding. Khordad confers exactly with Gemini, the passage of the sun through the ecliptical segment of 60 - 90 degrees from vernal equinox.
There might also be a red 'equinox stone' on the east side of the Long Meg circle (as at Swinside and Castlerigg stone circle), involved in the Autumn equinox and Vernal equinox sunrises and sunsets.Hood, 2004, p.1-25, quoted by Barrowclough, p.129-131 The Long Meg stones may be involved not just with solar timings, but also with lunar ones as well (most northerly/southerly Moon rises and sets).
The facility contains solar-powered hot showers, photo-voltaic solar energy and compostable, odorless toilets. Communal breakfast and dinner meals are included with the stay and are served family-style. Visitors are encouraged to minimize their food waste during meals, and leftover food is composted via a vermiculture program. View of the sunrise from the Star Base during the 2004 vernal equinox The Hike Inn can only be reached by foot.
Other books have also been published about this holiday. 12 Farvardin is also the day of the Martyrdom of Imam Ali al-Hadi. The day usually falls on 1 April, however, as it is determined by the vernal equinox, the date can change if the equinox does not fall on 21 March. In 2016, it was on 31 March, and in 2017 and 2019 the date was back to 1 April.
Energy Concerns Push Clocks Forward this Weekend by Nell Boyce. Morning Edition, National Public Radio, 9 March 2007. There is very little recent research on what the actual positive effects, if any, might be. Since DST moves sunrise one hour later by the clock, late sunrise times become a problem when DST is observed either too far before the vernal equinox or too far after the autumnal equinox.
Out From Boneville is the first story-arc in the Bone series. It collects the first six issues of Jeff Smith's self-published Bone comics. It marks the beginning of part one (of three) of the Bone series, titled Vernal Equinox. The book was first published by Cartoon Books in its original black-and-white version in 1995; excerpts were printed in Disney Adventures over the course of 1994–1998.
While there are many holidays and events in Ásatrú, the following are official in the European Odinist Circle: ;January (Snowmoon) :January 21: Anniversary of the founding of the Spanish Odinist Circle in 1981. ;April (Grasamenoþs) :First full moon after the vernal equinox: Ostara festival. It represents the beginning of life after winter, when light and life come back into the souls of men. ;May (Merrymoon) :May 1: Walpurgisnacht.
The directions north and south on the celestial sphere are in the sense toward the north celestial pole and toward the south celestial pole. East is the direction toward which Earth rotates, west is opposite that. The crossing from south to north is known as the vernal equinox, also known as the first point of Aries and the ascending node of the ecliptic on the celestial equator.Astronomical Almanac 2010, p.
R Turcan. 1996. The Cults of the Roman Empire. p44-47 The naming of Aries is late in the Babylonian zodiac where the equinox was in its earliest tradition marked as in the early Middle Bronze Age by actual coincidence with the Pleiades. The time also corresponds to the time of castration of male calves, mules and donkeys, Sanguia on the vernal equinox and marked the start of spring proper.
The equinox may be taken to mark the end of astronomical summer and the beginning of astronomical autumn (autumnal equinox) in the Northern Hemisphere, while marking the end of astronomical winter and the start of astronomical spring (vernal equinox) in the Southern Hemisphere. The Autumnal and Spring equinoxes mark the point in the calendar at which the length of night and the length of day are almost exactly equal.
It is 5.39 degrees north of the ecliptic, so it can be occulted by the Moon. Such occultations occur when the Moon's ascending node is near the vernal equinox, as was the case in 2007. Most occultations are visible only in the Southern Hemisphere, because the star is at the northern edge of the lunar occultation zone. Rarely, it may be occulted as far north as southern California.
Nowruz marks the first day of spring and the beginning of the year in Iranian calendar. It is celebrated on the day of the astronomical vernal equinox, which usually occurs on March 21 or the previous/following day depending on where it is observed. geenani: It is celebrates when the wheat is ripened and fully ready to harvest. It is very old tradition to welcome the grains of wheat at homes.
Nakshatra (Sanskrit: नक्षत्र, IAST: Nakṣatra) is the term for lunar mansion in Hindu astrology and Indian Astronomy. A nakshatra is one of 28 (sometimes also 27) sectors along the ecliptic. Their names are related to a prominent star or asterisms in or near the respective sectors. The starting point for the nakshatras according to Vedas is "Kritika" (it has been argued because the Pleiades may have started the year at the time the Vedas were compiled, presumably at the vernal equinox), but, in more recent compilations, the start of the nakshatras list is the point on the ecliptic directly opposite to the star Spica called Chitrā in Sanskrit, which would be Ashvinī, an asterism that is part of the modern constellation Aries, and these compilations therefore may have been compiled during the centuries when the sun was passing through the area of the constellation Aries at the time of the vernal equinox.
Illumination of the Earth by the Sun on the day of equinox Nowruz's timing in Iran is based on Solar Hijri algorithmic calendar, which is based on precise astronomical observations, and moreover use of sophisticated intercalation system, which makes it more accurate than its European counterpart, the Gregorian calendar. Each 2820 year great grand cycle contains 2137 normal years of 365 days and 683 leap years of 366 days, with the average year length over the great grand cycle of 365.24219852. This average is just 0.00000026 (2.6×10−7) of a day shorter than Newcomb's value for the mean tropical year of 365.24219878 days, but differs considerably more from the current average vernal equinox year of 365.242362 days, which means that the new year, intended to fall on the vernal equinox, would drift by half a day over the course of a cycle. As the source explains, the 2820-year cycle is erroneous and has never been used in practice.
Unlike before, during Perestroika where the holiday was only allowed to celebrate at the Lenin Square. Every year on 22 March, from morning to midnight thousands of Almaty residents came to the square to celebrate the national holiday of the vernal equinox - Nauryz. In the square, every year on March 22, tents were put out, which sold baursaks, leather, rice and soft drinks. Festive concerts were also held by famous Kazakh stars.
For seven months of the year (from May to November) this range exceeds daily. Waves of intense cold occur, lasting for several days, and one may have to endure temperatures of , rising to a maximum of . At Ghazni the snow has been known to stay long beyond the vernal equinox; the temperatures sink as low as . Oral tradition tells the destruction of the entire population of Ghazni by snowstorms more than once.
Third edition, Cambridge University Press (2008). and generally falls on 14 April of the Gregorian year. 14 April marks the first day of the traditional Tamil calendar and is a public holiday in the state of Tamil Nadu, Sri Lanka and Mauritius. Tropical vernal equinox fall around 22 March, and by adding 23 degrees of trepidation (oscillation) to it, we get the Hindu sidereal or Nirayana Mesha Sankranti (Sun's transition into nirayana Aries).
From our perspective on Earth, the stars are ever so slightly 'moving' from west to east at the rate of one degree approximately every 72 years. One degree is about twice the diameter of the Sun or Moon as viewed from Earth. The easiest way to notice this slow movement of the stars is at any fixed time each year. The most common fixed time is at the vernal equinox around 21 March each year.
Children celebrating Navruz in Samarkand in 19th-century Russian Turkestan (now Uzbekistan) Navruz () is celebrated widely in Uzbekistan. It is the day of the vernal equinox, and marks the beginning of spring in the Northern Hemisphere. It has been celebrated on the territory corresponding to modern- day Uzbekistan for at least two thousand years. When Uzbekistan was part of the Soviet Union, celebrations of Navruz were generally unofficial, and at times even prohibited.
When the data are dependent for their values on a particular coordinate system, the date of that coordinate system needs to be specified directly or indirectly. Celestial coordinate systems most commonly used in astronomy are equatorial coordinates and ecliptic coordinates. These are defined relative to the (moving) vernal equinox position, which itself is determined by the orientations of the Earth's rotation axis and orbit around the Sun. Their orientations vary (though slowly, e.g.
During the equinoxes, the sun enters again through the gate and "produces a distinctive rectangular shaft of light" (Zoll 2012, p. 15). Outside this circular feature, is a Bear Claw petroglyph, which at vernal equinox sunset, fits into a shaft of light produced by a natural rock grouping. " Both the Hopi and Zuni have bear clans or bear societies who may have created this image for reasons unknown"(Zoll 2012 p. 18).
The lunar nodes are the points where the Moon's orbit intersects the ecliptic. The first type of lunar precession is that of the plane of the Moon's orbit. The period of the lunar nodal precession is defined as the time it takes the ascending node to move through 360° relative to the vernal equinox (autumnal equinox in Southern Hemisphere). It is about 18.6 years and the direction of motion is westward, i.e.
In Persia (Iran) after the reform in the Persian calendar by introduction of the Persian Zoroastrian (i. e. Young Avestan) calendar in 503 BC and afterwards, the first day of the year (1 Farvardin=Nowruz) slipped against the vernal equinox at the rate of approximately one day every four years.Hartner, Willy. "The young Avestan and Babylonian calendars and the antecedents of precession." Journal for the History of Astronomy 10 (1979): 1. pp. 1–22.
Years in the Baháʼí calendar are counted from Thursday 21 March 1844, the beginning of the Baháʼí Era or Badíʿ Era (abbreviated BE or B.E.). Year 1 BE thus began at sundown 20 March 1844. The length of each year is strictly defined as the number of days between the opening and closing days of the year, with the number of intercalary days adjusted as needed. The year ends on the day before the following vernal equinox.
The moveable feasts are those connected with the Easter cycle, and Easter is the date relative to which their position is ultimately determined. The date of Easter is determined relative to the lunar calendar as used by the Hebrews. The rule has since the Middle Ages been phrased as "Easter is observed on the Sunday after the first full moon on or after the day of the vernal equinox." However, this does not reflect the actual ecclesiastical rules precisely.
Beta Arietis is the star's Bayer designation. It also bears the Flamsteed designation 6 Arietis. The traditional name, Sheratan (or Sharatan, Sheratim), in full Al Sharatan, is from the Arabic الشرطان aš-šaraţān "the two signs", a reference to the star having marked the northern vernal equinox together with Gamma Arietis several thousand years ago. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalogue and standardize proper names for stars.
In 1943 Easter fell on Sunday, April 25. The last ecclesiastical full moon preceding the Paschal did not occur until Saturday, March 20; prior to March 21, the fixed date to which the vernal equinox is assigned for the purposes of the computus, meaning the Paschal full moon did not happen until Sunday, April 18. Consequently, Easter was the following Sunday (April 25). Easter will not fall as late again until 2038—a span of 95 years.
The vernal equinox point is one of the two where the ecliptic intersects the celestial equator. Analogous to terrestrial longitude, right ascension is usually measured in sidereal hours, minutes and seconds instead of degrees, a result of the method of measuring right ascensions by timing the passage of objects across the meridian as the Earth rotates. There are = 15° in one hour of right ascension, and 24h of right ascension around the entire celestial equator. Astronomical Almanac 2010, p.
It is customary to specify positions of celestial bodies with respect to the vernal equinox. Because of Earth's precession of the equinoxes, this point moves back slowly along the ecliptic. Therefore, it takes the Moon less time to return to an ecliptic longitude of 0° than to the same point amid the fixed stars: days (27 d 7 h 43 m 4.7 s). This slightly shorter period is known as the tropical month; compare the analogous tropical year.
The positions of the solstices and equinoxes in the Vedanga Jyotisha, with the sun very close to the Krittika at the Vernal Equinox., would correspond to about 1370 BCE,Sastry 1985Bryant 2001:259. Keith 1912 although the text in its present form is from a later date, around 700 - 600 BCE. The Vedanga Jyotisha, in common with Mesopotamian texts, asserts a 3:2 ratio between the durations of daylight on the longest and shortest days of the year.
Jakatdar suggests a shift in the contemporary temperament regarding the traditional approach to calculating such events, to accommodate the ever increasing complexity of modern life. The muhūrt has the same utility in the marriage rites in Hinduism. Another example is the so-called Brahma Muhūrta, which is about one and a half hours before sunrise. This particular time, which is associated with the constellations during the Vernal Equinox, is said to be auspicious for practicing yoga.
The Surya Siddhanta defines Uttarayana as the period between the Makara Sankranti (which currently occurs around January 14) and Karka Sankranti (which currently occurs around July 16). Bal Gangadhar Tilak proposes an alternative, early vedic definition of Uttarayana as starting from Vernal Equinox and ending with Autumnal Equinox. This definition interprets the term "Uttara Ayana" as "northern movement" instead of "northward movement", i.e. as the movement of the Earth in the region North of the Equator.
Earth's rotation period relative to the International Celestial Reference Frame, called its stellar day by the International Earth Rotation and Reference Systems Service (IERS), is seconds of mean solar time (UT1) , ). Earth's rotation period relative to the precessing mean vernal equinox, named sidereal day, is of mean solar time (UT1) , ). Thus, the sidereal day is shorter than the stellar day by about . Both the stellar day and the sidereal day are shorter than the mean solar day by about .
Because the signs are each 30° in longitude but constellations have irregular shapes, and because of precession, they do not correspond exactly to the boundaries of the constellations after which they are named. These astrological signs form a celestial coordinate system, or even more specifically an ecliptic coordinate system, which takes the ecliptic as the origin of latitude and the Sun's position at vernal equinox as the origin of longitude.; numerous examples of this notation appear throughout the book.
The introduction of intercalation marked an important break from Islam, as under the Islamic calendar the practice of intercalation had been specifically prohibited in the Qurʼan. The number of the intercalary days is determined in advance to ensure that the year ends on the day before the next vernal equinox. This results in 4 or 5 intercalary days being added. These days are inserted between the 18th and 19th months, falling around the end of February in the Gregorian calendar.
It was used by Javanese courts until 1633, when it was replaced by Anno Javanico, a hybrid Javanese-Islamic system. It was adopted as the era of the Indian national calendar (also known as "Śaka calendar") in 1957 but not widely used. The Shaka era is the vernal equinox of the year AD 78. The year of the official Shaka Calendar is tied to the Gregorian date of 22 March every year, except in Gregorian leap years when it starts on 21 March.
Its surface is 80.9% water, compared with 60.7% water in the case of the Northern Hemisphere, and it contains 32.7% of Earth's land. Owing to the tilt of Earth's rotation relative to the Sun and the ecliptic plane, summer is from December to February (inclusive) and winter is from June to August (inclusive). September 22 or 23 is the vernal equinox and March 20 or 21 is the autumnal equinox. The South Pole is in the center of the southern hemispherical region.
This helps give the proper ascension and decline coordinates of the celestial bodies as they travel through space. The zero point for ascension and decline coordinates of the celestial bodies as they travel through space. The zero point for ascension is set to the vernal equinox while the end measurement (decline) is the equator, this would put the North Pole at the 90 degree point. The third and most commonly seen configuration of the "torquetum" uses all its assets to make measurements.
The apparent motion of the Sun along the ecliptic (red) as seen on the inside of the celestial sphere. Ecliptic coordinates appear in (red). The celestial equator (blue) and the equatorial coordinates (blue), being inclined to the ecliptic, appear to wobble as the Sun advances. The celestial equator and the ecliptic are slowly moving due to perturbing forces on the Earth, therefore the orientation of the primary direction, their intersection at the Northern Hemisphere vernal equinox, is not quite fixed.
Traditionally, the Japanese Peace Bell is rung twice a year. It is tolled on the first day of Spring at the time of the vernal equinox, in celebration of the annual Earth Day ceremony initiated by Earth Day Founder, John McConnell. It is also tolled on every opening day of the UN General Assembly's yearly session in September, coinciding with the International Day of Peace established by the General Assembly in 1981. This occasion is observed by the Secretary-General.
The location of the celestial poles of some selected Solar System objects is shown in the following table. The coordinates are given relative to Earth's celestial equator and the vernal equinox as they existed at J2000 (2000 January 1 12:00:00 TT) which is a plane fixed in inertial space now called the International Celestial Reference Frame (ICRF). Many poles precess or otherwise move relative to the ICRF, so their coordinates will change. The Moon's poles are particularly mobile.
The first day of the Iranian calendar falls on the March equinox, the first day of spring, around March 21. In the 11th century CE the Iranian calendar was reformed in order to fix the beginning of the calendar year, i.e. Nowruz, at the vernal equinox. Accordingly, the definition of Nowruz given by the Iranian scientist Tusi was the following: "the first day of the official New Year [Nowruz] was always the day on which the sun entered Aries before noon."R.
This is an evolved red giant star with a stellar classification of M2.5 IIIb. It is a semiregular variable that ranges between magnitudes 5.11 and 5.17. Hipparcos mission photometry gives an amplitude variation of 0.0148 in magnitude with a frequency of 11.4 cycles per day. In terms of its right ascension coordinates, φ Pegasi is located very near the line of the vernal equinox and will cross over around the year 3030, due to the precession of the Earth's axis.
Each circle is made from rounded river stones brought from another river approximately 7 kilometers away. Each circle in concentric, with and inner and an outer ring separated by an open strip approximately 8 meters wide. Each circle contains smaller clusters of stone, including standing stones surrounded by elongated stones in a radiating orientation, forming a sundial which points toward the sunset on the summer solstice and allows for calculation of the winter solstice, the vernal equinox and the sun's movements.
Landed was recorded at Inner Space Studios in Weilerswist near Cologne, in 1975. It was engineered by Holger Czukay at Inner Space Studios. Side A was mixed by Toby Robinson and Holger Czukay at Studio Dierks in Stommeln, Germany, while side B was mixed by Czukay at Inner Space Studios, both sides under the assistance of René Tinner. The album was produced by the band themselves, and produced a single, "Hunters and Collectors", backed by "Vernal Equinox", which was issued on Virgin that same year.
Around AD 200, Clement of Alexandria wrote: Various factors contributed to the selection of December 25 as a date of celebration: it was the date of the winter solstice on the Roman calendar and it was nine months after March 25, the date of the vernal equinox and a date linked to the conception of Jesus (now Annunciation). Christmas played a role in the Arian controversy of the fourth century. After this controversy ran its course, the prominence of the holiday declined for a few centuries.
Burning the Böögg around 1900 The roots of the festival go back to medieval times when the first day of summer working hours was celebrated in the guildhalls across the city. City ordinances strictly regulated the length of the working day in that era. During the winter semester the workday in all workshops lasted as long as there was daylight, but during the summer semester (i.e. starting on Monday following vernal equinox) the law proclaimed that work must cease when the church bells tolled at six o'clock.
In addition to the eclipse, 20 March 2015 was also the day of the March equinox (also known as the spring or vernal equinox in the Northern Hemisphere). In addition, six supermoons were expected for 2015. The supermoon on 20 March 2015 was the third of the year; however, it was a new moon (near side facing away from the sun), and only its shadow was visible. At greatest eclipse, the Sun was at its zenith less than 24 kilometers south of the Equator.
This motion, which is caused mostly by the Moon's gravity, gives rise to the precession of the equinoxes in which the Sun's position on the ecliptic at the time of the vernal equinox, measured against the background of fixed stars, gradually changes with time. In graphical terms, the Earth behaves like a spinning top, and tops tend to wobble as they spin. The spin of the Earth is its daily (diurnal) rotation. The spinning Earth slowly wobbles over a period slightly less than 26,000 years.
As seen from above the Earth's north pole, a star's local hour angle (LHA) for an observer near New York (red dot). Also depicted are the star's right ascension and Greenwich hour angle (GHA), the local mean sidereal time (LMST) and Greenwich mean sidereal time (GMST). The symbol ʏ identifies the vernal equinox direction. Assuming in this example the day of the year is the March equinox so the sun lies in the direction of the grey arrow then this star will rise about midnight.
He was accompanied by Yeou-kang, a constellation depicting an official in charge of pasture distribution. In a similar system to the Chinese, the first lunar mansion in Hindu astronomy was called "Aswini", after the traditional names for Beta and Gamma Arietis, the Aswins. Because the Hindu new year began with the vernal equinox, the Rig Veda contains over 50 new-year's related hymns to the twins, making them some of the most prominent characters in the work. Aries itself was known as "Aja" and "Mesha".
This, as well as observations of the changing positions of stars Sirius and Arcturus, led to the discovery of proper motion. Based on present day observations, the position of Aldebaran has shifted 7′ in the last 2000 years; roughly a quarter the diameter of the full moon. Due to precession of the equinoxes, 5,000 years ago the vernal equinox was close to Aldebaran. English astronomer William Herschel discovered a faint companion to Aldebaran in 1782; an 11th-magnitude star at an angular separation of 117″.
The word Agrahāyaṇa means the month of Ayana or Equinox (agra = first + ayana = travel of the sun, equinox). The aligning of this name with the Mṛgaśiras Nakṣatra (Lambda Orionis), gives rise to speculation that this name was given when the sun was near Orion at the time of the vernal equinox, i.e. around 7000 years ago. In lunar religious calendars, Agrahāyaṇa may begin on either the new moon or the full moon around the same time of year, and is usually the 9th month of the year.
The physical construction of the house required setting up four posts to represent the four cardinal directions, "aligned almost exactly with the north-south, east-west axis."Patricia J. O'Brien, "Prehistoric evidence of Pawnee Cosmology", American Anthropologist (New Series) Vol. 88, No. 4 (Dec 1986), pp 939–946 A Pawnee observatory-lodge also required an unobstructed view of the eastern sky. The lodge's axis would be oriented east-west in such a way that the sunrise of vernal equinox would cast light on the altar.
In Christendom, under which the Gregorian Calendar developed, New Year's Day traditionally marks the Feast of the Circumcision of Christ, which is still observed as such by the Anglican Church and the Lutheran Church. Mesopotamia (modern-day Iraq) instituted the concept of celebrating the new year in 2000BC and celebrated new year around the time of the vernal equinox, in mid-March. The early Roman calendar designated 1 March as the first day of the year. The calendar had just 10 months, beginning with March.
"Chyl-Pazhi" is the national holiday of the peoples of the Sayan-Altai (which include Shors and Teleuts, native residents of the Kuzbass), in Russian translation it is "the head of year". The first rays of "new sun" fall on this head in the days of the vernal equinox. In the past this holiday opened new life cycle and it was particularly significant for the peoples of the Sayan-Altai. Traditional Festival of bell ringers "Rings over Tom" takes place in the day of Whitsun.
The Baháʼí calendar is based upon the calendar established by the Báb. The year consists of 19 months, each having 19 days, with four or five intercalary days, to make a full solar year. The Baháʼí New Year corresponds to the traditional Iranian New Year, called Naw Rúz, and occurs on the vernal equinox, near 21 March, at the end of the month of fasting. Baháʼí communities gather at the beginning of each month at a meeting called a Feast for worship, consultation and socializing.
Eggs balanced on a flat surface Egg balancing is a traditional Chinese practice that has since been popularized in the United States. Although the irregular shape of eggs makes this somewhat difficult, eggshells typically have many imperfections such that the vast majority can be balanced with minimal effort. Despite folklore connecting this practice to the lunar new year in China, the Dragon Boat Festival in Taiwan and the vernal equinox in the United States, egg balancing can be done throughout the year and has no connection to the gravitational force of the moon or sun.
The meteoroids spread out along the entire orbit of the comet to form a meteoroid stream, also known as a "dust trail" (as opposed to a comet's "dust tail" caused by the very small particles that are quickly blown away by solar radiation pressure). The frequency of fireball sightings increases by about 10–30% during the weeks of vernal equinox. Even meteorite falls are more common during the northern hemisphere's spring season. Although this phenomenon has been known for quite some time, the reason behind the anomaly is not fully understood by scientists.
The SI second was made equal to the ephemeris second in 1967. Earth's rotation period relative to the fixed stars, called its stellar day by the International Earth Rotation and Reference Systems Service (IERS), is seconds of mean solar time (UT1) Earth's rotation period relative to the precessing or moving mean vernal equinox, its sidereal day, is seconds of mean solar time (UT1) Thus the sidereal day is shorter than the stellar day by about 8.4 ms.Explanatory Supplement to the Astronomical Almanac, ed. P. Kenneth Seidelmann, Mill Valley, Cal.
World Sleep Day (the Friday before the northern hemisphere vernal equinox) is an annual event organized by the World Sleep Day Committee of the World Sleep Society, formerly World Association of Sleep Medicine (WASM), since 2008.World Sleep Day World Association of Sleep Medicine, accessed 19 March 2011 The goal is to celebrate the benefits of good and healthy sleep and to draw society's attention to the burden of sleep problems and their medical, educational, and social aspects, and to promote the prevention and management of sleep disorders.
Nutation is the smaller amplitude shorter-period (< 18.6 years) wobble that is superposed on the precessional motion of the Celestial pole. It is due to shorter-period fluctuations in the strength of the torque exerted on Earth's equatorial bulge by the sun, moon, and planets. When the short-term periodic oscillations of this motion are averaged out, they are considered "mean" as opposed to "true" values. Thus, the vernal equinox, the equatorial plane of the Earth, and the ecliptic plane vary according to date and are specified for a particular epoch.
While the Nisan-years begin the year around the Vernal equinox (Spring equinox) (Gregorian March 20/21), the Tishri-years begin the years around the Autumn equinox (Gregorian September 22/23). The New Year's Day of the Tishri-years is called Rosh Hashanah ("Head of the Year"); it begins the Fall Feasts of Israel. Tishri 1, however, is not determined directly by its relationship to the Autumn Equinox. It depends on the determination of Nisan 1, which is the day after the new moon closest to the Spring Equinox (within fifteen days before or after).
Also note that the daily rotation of the Earth around its axis is opposite to the precessional rotation. When the polar axis precesses from one direction to another, then the equatorial plane of the Earth (indicated with the circular grid around the equator) and the associated celestial equator will move too. Where the celestial equator intersects the ecliptic (red line) there are the equinoxes. As seen from the drawing, the orange grid, 5000 years ago one intersection of equator and ecliptic, the vernal equinox was close to the star Aldebaran of Taurus.
A non-inclined orbit is an orbit coplanar with a plane of reference. The orbital inclination is 0° for prograde orbits, and π (180°) for retrograde ones. If the plane of reference is a massive spheroid body's equatorial plane, these orbits are called equatorial; if the plane of reference is the ecliptic plane, they are called ecliptic. As these orbits lack nodes, the ascending node is usually taken to lie in the reference direction (usually the vernal equinox), and thus the longitude of the ascending node is taken to be zero.
The City Dionysia (Dionysia ta en Astei – Διονύσια τὰ ἐν Ἄστει, also known as the Great Dionysia, Dionysia ta Megala – Διονύσια τὰ Μεγάλα) was the urban part of the festival, possibly established during the tyranny of Peisistratus in the 6th century BC. This festival was held probably from the 10th to the 16th of the month ElaphebolionMikalson, p. 137. (the lunar month straddling the vernal equinox, i.e., Mar.-Apr in the solar calendar), three months after the rural Dionysia, probably to celebrate the end of winter and the harvesting of the year's crops.
Gabriel told Mary to name her son Jesus, meaning "YHWH is salvation". According to , the Annunciation occurred "in the sixth month" of Elizabeth's pregnancy with John the Baptist. Many Christians observe this event with the Feast of the Annunciation on 25 March, an approximation of the northern vernal equinox nine full months before Christmas, the ceremonial birthday of Jesus. The Annunciation is a key topic in Christian art in general, as well as in Marian art in the Catholic Church, having been especially prominent during the Middle Ages and Renaissance.
Model of the main procession street (Aj-ibur-shapu) towards Ishtar Gate Once per year, the Ishtar Gate and connecting Processional Way were used for a New Year's procession, which was part of a religious festival celebrating the beginning of the agricultural year. In Babylon, the rituals surrounding this holiday lasted twelve days. The New Year's celebrations started immediately after the barley harvest, at the time of the vernal equinox. This was the first day of the ancient month of Nisan, equivalent to today's date of March 20 or 21.
The Quartodeciman controversy arose because Christians in the churches of Jerusalem and Asia Minor observed Passover on the 14th of the first month (Nisan), no matter the day of the week on which it occurred, while the churches in and around Rome changed to the practice of celebrating Easter always on the Sunday following first Full Moon following the vernal equinox, calling it "the day of the resurrection of our Saviour". The difference was turned into an ecclesiastical controversy when the practice was condemned by synods of bishops.
Close to the equator they tend to happen around the autumnal equinox and the vernal equinox; farther from the equator they tend to happen closer to the winter solstice. In either case, the two intervals when transits can take place occur more or less symmetrically before and after the winter solstice (however, the large eccentricity of Mars's orbit prevents true symmetry). MER Spirit Observers on Mars can also view lunar eclipses of Phobos and Deimos. Phobos spends about an hour in Mars's shadow; for Deimos it is about two hours.
The Julian calendar reform lengthened seven months and replaced the intercalary month with an intercalary day to be added every four years to February. It was based on a length for the year of 365 days and 6 hours (365.25 d), while the mean tropical year is about 11 minutes and 15 seconds less than that. This had the effect of adding about three quarters of an hour every four years. The effect accumulated from inception in 45 BC until the 16th century, when the northern vernal equinox fell on 10 or 11 March.
Painting huge eggs for Nowruz at Milad Tower Iran's official New Year begins with Nowruz, an ancient Iranian tradition celebrated annually on the vernal equinox. It is enjoyed by people adhering to different religions, but is considered a holiday for the Zoroastrians. It was registered on the UNESCO's list of Masterpieces of the Oral and Intangible Heritage of Humanity in 2009, described as the Persian New Year, Tehran Municipality organizes festivals during Nowruz. During Nowruz, many tourists visit the city and Nowruz is one of the best times for visiting Tehran.
As most countries and cultures of South and Southeast Asia lie within the Indian cultural sphere, the development of their traditional calendars have been strongly influenced by some form of the Hindu calendar. As in many other calendars, the New Year was based on the northern hemisphere vernal equinox (the beginning of spring). However, the Hindu calendar year was based on the sidereal year (i.e. the movement of the sun relative to the stars), while the Western Gregorian calendar is based on the tropical year (the cycle of seasons).
Historically, lunisolar calendars intercalated entire leap months on an observational basis. Lunisolar calendars have mostly fallen out of use except for liturgical reasons (Hebrew calendar, various Hindu calendars). A modern adaptation of the historical Jalali calendar, known as the Solar Hijri calendar (1925), is a purely solar calendar with an irregular pattern of leap days based on observation (or astronomical computation), aiming to place new year (Nowruz) on the day of vernal equinox (for the time zone of Tehran), as opposed to using an algorithmic system of leap years.
This varies year to year between March 19–22, though it usually falls on March 20 or March 21. The date of the holiday occurs at the same time of the Iranian new year (Norouz), which is celebrated in many places throughout the Middle East and Central Asia. It also corresponds with the beginning of the Baháʼí calendar, which is celebrated as Baháʼí Naw-Rúz. Other holidays occurring around this time include Ostara (amongst neopagans), Chunfen in China, and Vernal Equinox Day (a public holiday in Japan), among others.
Moreover, Neugebauer not only ignored the difference between the classical Alexandrian and the Festal Index 19-year lunar cycle, but also kept us guessing about, at least refrained from showing, the (crucial) position of the saltus in the particular Metonic 19-year lunar cycle in question.Neugebauer (1979) 98-100 Anatolius describes the vernal equinox as a section of the first zodiacal sign from March 22 to 25. Although he defines March 22 as the Sun's entry into the first sign, he never defines it as his equinox, but as Ptolemy's equinox.
For nine days feasts and sacrifices of this kind are celebrated. > Every day they sacrifice one human being in addition to other animals, so > that in nine days there are 72 victims which are sacrificed. This sacrifice > takes place about the time of the vernal equinox. It was a symbolic moment when Pope John Paul II visited Scandinavia in 1989 and held an open-air mass at the royal mounds in Gamla Uppsala, as this was a Norse religion cultic centre, which became Sweden's first archbishopric in 1164.
The purpose of the instrument was to standardise the measurement of time and the calendar. The convention in Sicily had been that the (24-hour) day was measured from the moment of sun-rise, which of course meant that no two locations had the same time and, more importantly, did not have the same time as in St. Peter's Basilica in Rome. It was also important to know when the Vernal equinox occurred, to provide the correct date for Easter. On the belltowers there were six medieval bells.
As the number of recognised species increased, various attempts were made to divide the species into subgroups, usually on the basis of the pattern of the emerging leaves (vernation). In the era of molecular phylogenetics this characteristic has been shown to be unreliable and now seven molecularly defined clades are recognised that correspond to the biogeographical distribution of species. New species continue to be discovered. Most species flower in winter, before the vernal equinox (20 or 21 March in the Northern Hemisphere), but some flower in early spring and late autumn.
Baháʼís interpret this formula as a specification of the vernal equinox, though where that should be determined was not defined. The calendar was first implemented in the West in 1907. The Baháʼí scriptures left some issues regarding the implementation of the Badíʿ calendar to be resolved by the Universal House of Justice before the calendar can be observed uniformly worldwide. On 10 July 2014 the Universal House of Justice announced provisions that will enable the common implementation of the Badíʿ calendar worldwide, beginning at sunset 20 March 2015, coinciding with the completion of the ninth cycle of the calendar (see below).
According to Sallustius, the cutting of the tree was accompanied by fasting, "as though we were cutting off the further progress of generation; after this we are fed on milk as though being reborn; that is followed by rejoicings and garlands and as it were a new ascent to the gods."Sallustius, Peri Theōn 4.10, as cited by Alvar, Romanising Oriental Gods, p. 277. The garlands and rejoicing (Hilaria) occurred on March 25, the vernal equinox on the Julian calendar, when Attis was in some sense "reborn" or renewed.Macrobius, Saturnalia 1.21.10; Forsythe, Time in Roman Religion, p. 88.

The twelve signs of the zodiac, miniatures from a book of hours. (The Sky: Order and Chaos by Jean-Pierre Verdet, from the 'New Horizons' series) In Western astrology, astrological signs are the twelve 30° sectors of the ecliptic, starting at the vernal equinox (one of the intersections of the ecliptic with the celestial equator), also known as the First Point of Aries. The order of the astrological signs is Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Each sector was named for a constellation within it in the time of naming.
This was the same discovery made earlier by the ancient Greek astronomer Hipparchus (c. 190-120 BC), who found that the measurements for either the sun's path around the ecliptic to the vernal equinox or the sun's relative position to the stars were not equal in length. Yu Xi wrote a critical analysis of the huntian (渾天) theory of the celestial sphere, arguing that the heavens surrounding the earth were infinite and motionless. He advanced the idea that the shape of the earth was either square or round, but that it had to correspond to the shape of the heavens enveloping it.
In 46 BC Julius Caesar decreed that the year would be made up of twelve months of approximately 30 days each to make a year of 365 days and a leap year of 366 days. The civil year had 365.25 days. This is the Julian calendar. The solar year has 365.2422 days and by 1582 there was an appreciable discrepancy between the winter solstice and Christmas and the Vernal equinox and Easter. Pope Gregory XIII, with the help of Italian astronomer Aloysius Lilius (Luigi Lilio), reformed this system by abolishing the days October 5 through October 14, 1582.
Nowruz (, ; ) is the Iranian New Year, also known as the Persian New Year, which is celebrated worldwide by various ethno-linguistic groups. Nowruz has Iranian and Zoroastrian origins; however, it has been celebrated by diverse communities for over 7,000 years in Western Asia, Central Asia, the Caucasus, the Black Sea Basin, the Balkans, and South Asia. It is a secular holiday for most celebrants that is enjoyed by people of several different faiths, but remains a holy day for Zoroastrians, Baháʼís, and some Muslim communities. Nowruz is the day of the vernal equinox, and marks the beginning of spring in the Northern Hemisphere.
However, there remained a small residual variation in the date and time of the vernal equinox of about ±27 hours from its mean position, virtually all because the distribution of 24 hour centurial leap-days causes large jumps (see Gregorian calendar leap solstice). This in turn raised the possibility that it could fall on 22 March, and thus Easter Day might theoretically commence before the equinox. The consulting astronomers chose the appropriate number of days to omit so that the equinox would swing from 19 to 21 March but never fall on 22 March (within Europe).
The zodiac is the belt or band of constellations through which the Sun, Moon, and planets move on their journey across the sky. Astrologers noted these constellations and so attached a particular significance to them. Over time they developed the system of twelve signs of the zodiac, based on twelve of the constellations through which the sun passes throughout the year, those constellations that are "Enlightened by the mind". Most western astrologers use the tropical zodiac beginning with the sign of Aries at the Northern hemisphere Vernal equinox always on or around March 21 of each year.
The Iranian calendars or Iranian chronology (, Gāh-Šomāri-ye Irāni) are a succession of calendars invented or used for over two millennia in Iran, also known as Persia. One of the longest chronological records in human history, the Iranian calendar has been modified time and again during its history to suit administrative, climatic, and religious purposes. The modern Iranian calendar is currently the official calendar in Iran. It begins at the midnight nearest to the instant of the vernal equinox as determined by astronomical calculations for the Iran Standard Time meridian (52.5°E or UTC+03:30).
APIN tablets indicate that the vernal equinox was marked by the Babylonian constellation known as "the hired man" (the modern Aries). In the Old Babylonian Epic of Gilgamesh, the goddess Ishtar sends Taurus, the Bull of Heaven, to kill Gilgamesh for spurning her advances. Enkidu tears off the bull's hind part and hurls the quarters into the sky where they become the stars we know as Ursa Major and Ursa Minor. Some locate Gilgamesh as the neighboring constellation of Orion, facing Taurus as if in combat, while others identify him with the sun whose rising on the equinox vanquishes the constellation.
The PLS was originally intended as an extension of the Yerkes–McDonald asteroid survey (1950–1952), which was initiated by Dutch–American astronomer Gerard Kuiper. While this survey was limited to a magnitude of up to 16, PLS could study minor planets up to a visual magnitudes of 20. However, it only covered a portion of the ecliptic about the vernal equinox, with the target areas selected to minimize the number of background stars. Photographic plates taken by Tom Gehrls at the Lunar and Planetary Laboratory in Arizona using the 48-inch Schmidt camera at Palomar Observatory.
Early names refer to the association with the religious feast of Candlemas (February 2) the optimum flowering time in which white-robed young women proceeded in the procession associated with the Purification of the Virgin, an alternative name for the feast day. The French name of refers to Candlemas, while an Italian name, , refers to purification. The German name of (little snow bells) also invokes the symbol of bells. In the language of flowers, the snowdrop is synonymous with 'hope', as it blooms in early springtime, just before the vernal equinox, and so, is seen as 'heralding' the new spring and new year.
The most famous structure is the Temple of the Seven Dolls, so named because of seven small effigies found at the site when the temple was discovered under the ruins of a later temple pyramid by archaeologists in the 1950s. On the vernal equinox, the site is crowded by visitors observing the sunrise through the temple's doorways, but there is no archaeological feature marking the observation spot; the relationship of the orientation with the equinoxes is thus highly unlikely. The temple is connected to the rest of the site by a sacbe, or "white road," so-called because they were originally coated with white limestone, built over stone- and-rubble fill.
Hipparchus's solution was to place the Earth not at the center of the Sun's motion, but at some distance from the center. This model described the apparent motion of the Sun fairly well. It is known today that the planets, including the Earth, move in approximate ellipses around the Sun, but this was not discovered until Johannes Kepler published his first two laws of planetary motion in 1609. The value for the eccentricity attributed to Hipparchus by Ptolemy is that the offset is of the radius of the orbit (which is a little too large), and the direction of the apogee would be at longitude 65.5° from the vernal equinox.
The granite coastline off Ocean View Boulevard in Pacific Grove Pacific Grove contains several habitat types including marine, littoral, pine forest and mixed oak woodland. The famed breeding habitat for the monarch butterfly is situated in the northwest part of town imbedded in residential neighborhoods in mixed oak forests. These monarchs migrate to reach Pacific Grove after their summer in the Rocky Mountains, often soaring as high as . South African Drosanthemum floribundum bloom late spring between Lovers Point and the Point Pinos Lighthouse The black-and-orange monarch butterflies spend much of the fall and winter in Monterey pine and eucalyptus trees, roughly from the vernal equinox through the spring equinox.
Naw-Rúz () is the first day of the Baháʼí calendar year and one of nine holy days for adherents of the Baháʼí Faith. It occurs on the vernal equinox, on or near March 21,which is the traditional Iranian New Year. The traditional Nowruz holiday, from which the Baha'i holiday derives, has been celebrated since ancient times in Iran, and is observed by culturally-adjacent peoples in Azerbaijan, Turkey, Iraq, Armenia, Georgia, Russia, Afghanistan, Pakistan, Syria, and Tajikistan. The Báb, the founder of Bábism, and then Baháʼu'lláh, the founder of the Baháʼí Faith, adopted the day as a holy day and associated it with the Most Great Name of God.
Krupp and Fairall find other problems with their arguments, including noting that if the Sphinx is meant to represent the constellation of Leo, then it should be on the opposite side of the Nile (the "Milky Way") from the pyramids ("Orion"), that the vernal equinox c. 10,500 BC was in Virgo and not Leo, and that in any case the constellations of the Zodiac originate from Mesopotamia and were completely unknown in Egypt until the much later Graeco-Roman era. Ed Krupp repeated this "upside down" statement in the BBC documentary Atlantis Reborn (1999). Bauval stated that some astronomers including Archie Roy of the University of Glasgow have rejected Krupp's argument.
The sidereal hour angle (SHA) of a body on the celestial sphere is its angular distance west of the vernal equinox generally measured in degrees. An alternate definition is that SHA of a celestial body is the arc of the Equinoctial or the angle at the celestial pole contained between the celestial meridian of the First point of Aries and that through the body, measured westward from Aries. The SHA of a star changes slowly, and the SHA of a planet doesn't change very quickly, so SHA is a convenient way to list their positions in an almanac. SHA is often used in celestial navigation and navigational astronomy.
Every year when the sun regains its strength and the vernal equinox promises that spring is coming, the pageant Carrus Navalis moves through the streets of Aalborg keeping an ancient tradition alive. The Carrus Navalis (Car-naval) parade in Aalborg is inspired by ancient pagan traditions and serves as a proclamation of spring, fantasy and fertility - and the start of a new carnival season. The pageant is composed of symbols and represents a part of an extensive carnival tradition that praises light’s triumph over darkness. The pageant is led by mask dancers and men with bells who chase away darkness, winter and evil spirits.
Naw-Rúz is one of nine holy days for adherents of the Baháʼí Faith worldwide. It is the first day of the Baháʼí calendar, occurring on the vernal equinox around March 21. The Baháʼí calendar is composed of 19 months, each of 19 days, and each of the months is named after an attribute of God; similarly each of the nineteen days in the month also are named after an attribute of God. The first day and the first month were given the attribute of Bahá, an Arabic word meaning splendour or glory, and thus the first day of the year was the day of Bahá in the month of Bahá.
The approximate 2,150 years for each age corresponds to the average time it takes for the vernal equinox to move from one constellation of the zodiac into the next. This average can be computed by dividing the earth's 25,800 year gyroscopic precession period by twelve, the number of zodiacal ‘signs’. According to various astrologers' calculations, approximate dates for entering the Age of Aquarius range from 1447 CE (Terry MacKinnell) to 3597 CE (John Addey). Astrologers do not agree on when the Aquarian age will start or even if it has already started. Campion (1999) lists various references from mainly astrological sources for the start of the Age of Aquarius.
If the astronomical calculation gives a Saturday for the first vernal full moon and Easter is not celebrated on the directly following Sunday but one week later, Easter is celebrated according to the computus one week too late in comparison to the astronomical result. He classified such cases a positive weekly (hebdomadal) paradox\ (H+ paradox). The discrepancies are even larger if there is a difference according to the vernal equinox with respect to astronomical theory and the approximation of the Computus. If the astronomical equinoctial full moon falls before the computistical equinoctial full moon, Easter will be celebrated four or even five weeks too late.
The southern stars are identified by CD and CPD numbers in a manner similar to the BD numbering system. A few decades later, the positional accuracy of the Durchmusterung catalogues began to be insufficient for many projects. To establish a more exact reference system for the Bonner Durchmusterung, astronomers and geodesists began to work on a fundamental celestial coordinate system based on the Earth's rotation axis, the vernal equinox and the ecliptic plane in the late 19th century. This astrometric project led to the Catalogues of Fundamental Stars of the Berlin observatory, and was used as an exact coordinate frame for the BD and AGK.
Thus why the Romans put so much trust in the "balanced sign". Going back to ancient Greek times, Libra the constellation between Virgo and Scorpio used to be ruled over by the constellation of Scorpio. They called the area the Latin word "chelae", which translated to "the claws" which can help identify the individual stars that make up the full constellation of Libra, since it was so closely identified with the Scorpion constellation in the sky. According to the tropical system of astrology, the Sun enters the sign of Libra when it reaches the northern autumnal equinox and the southern vernal equinox, which occurs around September 22.
15 (miscited as VI:15). Socrates Scholasticus unequivocally condemns the actions of the mob, declaring, "Surely nothing can be farther from the spirit of Christianity than the allowance of massacres, fights, and transactions of that sort." The Canadian mathematician Ari Belenkiy has argued that Hypatia may have been involved in a controversy over the date of the Christian holiday of Easter 417 and that she was killed on the vernal equinox while making astronomical observations. Classical scholars Alan Cameron and Edward J. Watts both dismiss this hypothesis, noting that there is absolutely no evidence in any ancient text to support any part of the hypothesis.
Soon Over Babaluma from 1974 continued in the ambient style of Future Days, yet it regained some of the abrasive edge of Tago Mago and Ege Bamyasi. In 1975, Can signed to Virgin Records in the UK and EMI/Harvest in Germany, appearing the same year on BBC's Old Grey Whistle Test where a memorable performance of Vernal Equinox involved Schmidt playing one keyboard section with a series of rapid karate chops. Shortly after the appearance Schmidt suffered a broken leg which led to cancellation of the band's UK tour. The later albums Landed (1975) and Flow Motion (1976) saw Can moving towards a somewhat more conventional style as their recording technology improved.
The calendars still had the same name, Shahenshahi (imperial), presumably because none were aware that the calendars were no longer the same. In 1745 the Parsis in and around Surat switched to the Kadmi or Kadimi calendar on the recommendation of their priests who were convinced that the calendar in use in the ancient homeland must be correct. Moreover, they denigrated the Shahenshahi calendar as being "royalist". In 1906 attempts to bring the two factions together resulted in the introduction of a third calendar based on an 11th-century Seljuk model: the Fasili, or Fasli, calendar had leap days intercalated every four years and it had a New Year's day that fell on the day of the vernal equinox.
The amount of Sun energy reaching a location on Earth ("insolation", shown in blue) varies through the seasons. As it takes time for the seas and lands to heat or cool, the surface temperatures will lag the primary cycle by roughly a month, although this will vary from location to location, and the lag is not necessarily symmetric between summer and winter. The diagram uses neopagan labelling; Litha is the summer solstice, Yule is the winter solstice, Ostara is the vernal equinox, and Mabon is the autumnal equinox. Earth's seasonal lag is largely caused by the presence of large amounts of water, which has a high latent heat of freezing and of condensation.
Sechseläuten is a Swiss German word that literally translates into "The six o'clock ringing of the bells". Changing to summer working hours traditionally was a joyous occasion because it marked the beginning of the season where people had some non-working daylight hours. Burnings of Böögg figures (the Swiss German term for "bogey", in origin scary- looking ragdolls) in spring are attested in various places of the city from the late 18th and early 19th century, without direct connection to the Sechseläuten. The combination of the Sechseläuten parade and the burning of an official Böögg was introduced in 1902. From 1902 until 1951, the holiday used to be held on the first Monday following vernal equinox.
Directly above the 24-hour dial is the dial of the Primum Mobile, so called because it reproduces the diurnal motion of the stars and the annual motion of the sun against the background of stars. It is basically an astrolabe drawn using a south polar projection, with a fixed tablet and a rete of special design that rotated once in a sidereal day. The rete was provided with 365 teeth, but was driven by a wheel with 61 teeth which made 6 turns in 24 hours. Thus the rete rotated once in 365/366 of a mean solar day, which equated 366 successive meridian transits of the vernal equinox with 365 similar transits of the sun.
By now (the yellow grid) it has shifted (red arrow) to somewhere in the constellation of Pisces. Note that this is an astronomical description of the precessional movement and the vernal equinox position in a given constellation may not imply the astrological meaning of an Age carrying the same name, as they (ages and constellations) only have an exact alignment in the "first point of Aries", meaning once in each c. 25800 (Great Sidereal Year). The Earth, in addition to its diurnal (daily) rotation upon its axis and annual rotation around the Sun, incurs a precessional motion involving a slow periodic shift of the axis itself: approximately one degree every 72 years.
Furthermore, some astrologers divide the ages in different ways. For example, Lcdr David Williams employs a decanate sub- division whereby each age is divided into three equal sections.Lcdr David Williams, Simplified Astronomy for Astrologers, 1980, American Federation of Astrologers, Tempe Arizona Robert Hand developed another approach entirely whereby the conjunction of the moving vernal point with specific stars within the zodiacal constellations provides an extra flavour to the corresponding historical events based on the nature of the star involved.Robert Hand, Cardinal Points, 1997 However Robert Hand believes that the moving Capricorn solstice point (around 20 December) near the modern New Year provides greater correlation to historical events compared to the vernal equinox.
The 1971 England rugby union tour of Far East was a series of matches played between September and October by an English national selection in Asia, as part of the RFU’s centenary celebrations. None of the six international matches on this tour were given official Test status, with England playing as England XV, No 'caps' were awarded to the English players who took part on the tour. The first match against Japan was played at the Kintetsu Hanazono Rugby Stadium, in Osaka, on the Friday, 24 September 1971, (Vernal Equinox Day, a public holiday in Japan), in front of a crowd of 13,000. The Japanese side was captained by 30 year old Akira Yokoi and coached by Tetsunosuke Onishi.
APIN reflects a tradition which marks the Pleiades as the vernal equinox, which was the case with some precision at the beginning of the Middle Bronze Age. The earliest identifiable reference to Aries as a distinct constellation comes from the boundary stones that date from 1350 to 1000 BC. On several boundary stones, a zodiacal ram figure is distinct from the other characters present. The shift in identification from the constellation as the Agrarian Worker to the Ram likely occurred in later Babylonian tradition because of its growing association with Dumuzi the Shepherd. By the time the MUL.APIN was created—by 1000 BC—modern Aries was identified with both Dumuzi's ram and a hired laborer.
From 1942 onwards, Nash often visited the artist Hilda Harrisson at her home, Sandlands on Boars Hill near Oxford, to convalesce after bouts of illness. From the garden at Sandlands, Nash had a view of the Wittenham Clumps, which he had first visited as a child and had painted both before World War I and again, as a background, in 1934 and 1935. He now painted a series of imaginative works of the Clumps under different aspects of the Moon. Paintings such as Landscape of the Vernal Equinox (1943) and Landscape of the Moon's Last Phase (1944) show a mystical landscape rich in the symbolism of the changing seasons and of death and rebirth.
The Babylonian calendar began with the first new moon after the March equinox, the day after the Sumerian goddess Inanna's return from the underworld (later known as Ishtar), in the Akitu ceremony, with parades through the Ishtar Gate to the Eanna temple, and the ritual re- enactment of the marriage to Tammuz, or Sumerian Dummuzi. The Persian calendar begins each year at the northward equinox, observationally determined at Tehran. The Indian national calendar starts the year on the day next to the vernal equinox on 22 March (21 March in leap years) with a 30-day month (31 days in leap years), then has 5 months of 31 days followed by 6 months of 30 days.
" Lovesphere 21 (and subsequent festivals) took place in Greensboro, North Carolina and featured Lawrence "Lipbone" Redding, Mark Engebretson, and guitar virtuoso Eugene Chadbourne. Of Lovesphere 23, critic Lauren Barber wrote, "the 23rd annual Lovesphere (is a) creative-arts performance project devised to usher in the vernal equinox... one of the festival’s core values (is) deep listening." Heidt wrote three librettos for composer Evan Hause's Defenstration Trilogy. Heidt's "engrossing " script for the second opera, Nightingale: The Last Days of James Forrestal "reflects, in accurate historical detail, on the political backstage manoeuvres that led to Forrestal's fall and on the dark side of his death....and can be considered a new chapter of its reception.
The Earth's apsidal precession slowly increases its argument of periapsis; it takes about years for the ellipse to revolve once relative to the fixed stars. The Earth's polar axis, and hence the solstices and equinoxes, precess with a period of about years in relation to the fixed stars. These two forms of 'precession' combine so that it takes between and years (and on average years) for the ellipse to revolve once relative to the vernal equinox, that is, for the perihelion to return to the same date (given a calendar that tracks the seasons perfectly). This interaction between the anomalistic and tropical cycle is important in the long-term climate variations on Earth, called the Milankovitch cycles.
Astronomically, the zodiac defines a belt of space extending 9° either side of the ecliptic, within which the orbits of the Moon and the principal planets remain. It is a feature of a celestial coordinate system centered upon the ecliptic, (the plane of the Earth's orbit and the Sun's apparent path), by which celestial longitude is measured in degrees east of the vernal equinox (the ascending intersection of the ecliptic and equator). Stars within the zodiac are subject to occultations by the Moon and other solar system bodies. These events can be useful, for example, to estimate the cross-sectional dimensions of a minor planet, or check a star for a close companion.
The Nineteen-Day Fast is a nineteen-day period of the year during which members of the Baháʼí Faith adhere to a sunrise-to-sunset fast. Along with obligatory prayer, it is one of the greatest obligations of a Baháʼí, and its chief purpose is spiritual: to reinvigorate the soul and bring the person closer to God. The fast was instituted by the Báb, and accepted by Baháʼu'lláh, the founder of the Baháʼí Faith, who stated its rules in his book of laws, the Kitáb-i-Aqdas. The nineteen days of fasting occur immediately before the beginning of the Baháʼí New Year, on the vernal equinox (19–21 March, depending on the year).
A 1945 Life article reported on "an egg-balancing craze" among the population of Chungking (the interim capital of China during World War II) on that year's Lichun. That article and subsequent followings-up started a similar egg-balancing craze in the United States, but transposed to the vernal equinox beginning Western spring on March 20 or 21 when the sun is at the celestial longitude of 0°. The idea that an egg is easier to balance on the spring equinox has since become an American urban legend, and egg-balancing events are sometimes held on that date. In 1976, New York artist Donna Henes started organizing egg-balancing ceremonies with the stated goal of bringing about world peace and international harmony.
North of the Tropic of Cancer, the noon shadow will always point north, and conversely, south of the Tropic of Capricorn, the noon shadow will always point south. The solar noon shadows of objects on points beyond and below subsolar points will point towards true north and true south respectively only when the solar declination has its maximum positive (δ☉ = +23.44°) or maximum negative (δ☉ = −23.44°) value. On the other hand, on the equinoxes when the sun is neither declined north nor south (δ☉ = 0°) and solar time noon shadows point NNW north of the equator and SSE south of the equator on the vernal equinox (and point NNE north of the equator and SSW south of the equator on the autumnal equinox).
Under the proposal, Easter would be defined as the first Sunday following the first astronomical full moon following the astronomical vernal equinox, as determined from the meridian of Jerusalem. The phrase "the first full moon after the equinox" is taken exactly: they each are instantaneous astronomical events; if the full moon occurs after the equinox, it is the Paschal full moon, even if they occur on the same day. An example would be the full moon at 04:05 Jerusalem time on 21 March 2019, after the equinox at 00:20 Jerusalem time the same day. The reform would have been implemented starting in 2001, the first year in which the Eastern and Western dates of Easter would coincide after this method was proposed in 1997.
However, because of the precession of the equinoxes, which is not constant, and the movement of the perihelion (which affects the Earth's orbital speed) the error with respect to the astronomical vernal equinox is variable; using the average interval between vernal equinoxes near 2000 of 365.24237 daysMeeus and Savoie (1992), p. 42 implies an error closer to 1 day every 7,700 years. By any criterion, the Gregorian calendar is substantially more accurate than the 1 day in 128 years error of the Julian calendar (average year 365.25 days). In the 19th century, Sir John Herschel proposed a modification to the Gregorian calendar with 969 leap days every 4000 years, instead of 970 leap days that the Gregorian calendar would insert over the same period.
Haft Mewa (Seven Fruit Syrup) is popularly consumed during Nowruz in Afghanistan Afghanistan's official New Year starts with Nowruz, an ancient tradition that started as a Zoroastrian celebration in present-day Iran, and with which it shares the annual celebration along with several other countries. It occurs every year at the vernal equinox. In Afghanistan, Nowruz is typically celebrated with music and dance, as well as holding buzkashi tournaments. Yaldā, another nationally celebrated ancient tradition, commemorates the ancient goddess Mithra and marks the longest night of the year on the eve of the winter solstice (; usually falling on 20 or 21 December), during which families gather together to recite poetry and eat fruits—particularly the red fruits watermelon and pomegranate, as well as mixed nuts.
The Iranian New Year's Day, Nowruz, which translates to "new day", is celebrated by Persians and other peoples of Iran to mark the beginning of spring on the vernal equinox on the first day of Farvardin, the first month of the Iranian calendar, which corresponds to around March 21 in the Gregorian calendar. An ancient tradition that has been preserved in Iran and several other countries that were under the influence of the ancient empires of Iran, Nowruz has been registered on UNESCO's Intangible Cultural Heritage Lists. In Iran, the Nowruz celebrations (incl. Charshanbe Suri and Sizdebedar) begin on the eve of the last Wednesday of the preceding year in the Iranian calendar and last on the 13th day of the new year.
Illumination of Earth by Sun on the day of an equinox The March equinox or Northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox (spring equinox) in the Northern Hemisphere and as the autumnal equinox in the Southern. On the Gregorian calendar, the Northward equinox can occur as early as 19 March or as late as 21 March at Greenwich. For a common year the computed time slippage is about 5 hours 49 minutes later than the previous year, and for a leap year about 18 hours 11 minutes earlier than the previous year.
This astronomical Easter was the Sunday after the full moon instant that was after the vernal equinox instant using Uraniborg time . However, it was delayed one week if that Sunday was the Jewish date Nisan15, the first day of Passover week, calculated according to modern Jewish methods. This Nisan15 rule affected two Swedish years, 1778 and 1798, that instead of being one week before the Gregorian Easter were delayed one week so they were on the same Sunday as the Gregorian Easter. Germany's astronomical Easter was one week before the Gregorian Easter in 1724 and 1744. Sweden's astronomical Easter was one week before the Gregorian Easter in 1744, but one week after it in 1805, 1811, 1818, 1825, and 1829.
Due to the discrepancies between the approximations of Computistical calculations of the time of the mean vernal equinox and the lunar phases, and the true values computed according to astronomical principles, differences occasionally arise between the date of Easter according to computistical reckoning and the hypothetical date of Easter calculated by astronomical methods using the principles attributed to the Church fathers. These discrepancies are called "paradoxical" Easter dates. In his Kalendarium of 1474, Regiomontanus computed the exact time of all conjunctions of the Sun and Moon for the longitude of Nuremberg according to the Alfonsine Tables for the period from 1475 to 1531. In his work he tabulated 30 instances where the Easter of the Julian computus disagreed with Easter computed using astronomical New Moon.
This new calendar was astronomically calculated, so that it did not have epagemonai – the months began when the sun entered a new sign of the zodiac. About 120 years after the reform of AD 1006, when the vernal equinox was starting to fall in Ardawahisht, Zoroastrians made it again coincide with nowruz by adding a second Spandarmad. This Shensai calendar was a month behind the qadimi still used in Persia, being used only by the Zoroastrians in India, the Parsees. On 6 June 1745 (Old Style) some Parsees re-adopted the qadimi calendar, and in 1906 some adopted the Fasli calendar in which 1 Frawardin was equated with 21 March, so that there was a sixth epagomenal day every four years.
The annual cycle of insolation for the northern hemisphere (Sun energy, shown in blue) with key points for seasons (middle), quarter days (top) and cross-quarter days (bottom) along with months (lower) and Zodiac houses (upper). The cycle of temperature (shown in pink) is delayed by seasonal lag. Derived from a reconstruction produced by linguist Jacob Grimm of an Old High German form of the Old English goddess name Ēostre, Ostara marks the vernal equinox in some modern Pagan traditions. Known as Alban Eilir, meaning Light of the Earth, to modern Druid traditions, this holiday is the second of three spring celebrations (the midpoint between Imbolc and Beltane), during which light and darkness are again in balance, with light on the rise.
To create a horoscope, an astrologer first has to ascertain the exact time and place of the subject's birth, or the initiation of an event. The local standard time (adjusting for any daylight saving time or war time) is then converted into Greenwich Mean Time or Universal Time at that same instant. The astrologer then has to convert this into the local sidereal time at birth in order to be able to calculate the ascendant and midheaven. The astrologer will next consult a set of tables called an ephemeris, which lists the location of the Sun, Moon and planets for a particular year, date and sidereal time, with respect to the northern hemisphere vernal equinox or the fixed stars (depending on which astrological system is being used).
Haft-Seen, a customary of Nowruz, the Iranian New Year Iran's official New Year begins with Nowruz, an ancient Iranian tradition celebrated annually on the vernal equinox. It is enjoyed by people adhering to different religions, but is considered a holiday for the Zoroastrians. It was registered on the UNESCO's list of Masterpieces of the Oral and Intangible Heritage of Humanity in 2009, described as the Persian New Year, shared with a number of other countries in which it has historically been celebrated. On the eve of the last Wednesday of the preceding year, as a prelude to Nowruz, the ancient festival of Čāršanbe Suri celebrates Ātar ("fire") by performing rituals such as jumping over bonfires and lighting off firecrackers and fireworks.
According to Ulansey, the tauroctony is a schematic star chart. The bull is Taurus, a constellation of the zodiac. In the astrological age that preceded the time of Hipparchus, the vernal equinox had taken place when the Sun was in the constellation of Taurus, and during that previous epoch the constellations of Canis Minor (The Dog), Hydra (The Snake), Corvus (The Raven), and Scorpius (The Scorpion) – that is, the constellations that correspond to the animals depicted in the tauroctony – all lay on the celestial equator (the location of which is shifted by the precession) and thus had privileged positions in the sky during that epoch. Mithras himself represents the constellation Perseus, which is located directly above Taurus the Bull: The same location occupied by Mithras in the tauroctony image.
The Catskill Mountain 3500 Club, incorporated as the Catskill 3500 Club and often just referred to as the 3500 Club, is a peakbagging organization for hikers in the Catskill Mountains of New York. Those wishing to become members must climb all 35 Catskill High Peaks and, in a departure from the requirements of most other such clubs, climb Slide, Blackhead, Balsam and Panther mountains again in winter, which is defined by the Club's by-laws as the period from December 21 to March 21 regardless of the actual occurrences of the winter solstice and vernal equinox in particular years. The Club also awards a separate patch for those who go on to climb all 35 peaks during winter. Until fairly recently it was the only hiking organization with a specific Catskill focus.
Representation of the intercalation scheme of the Jalali calendar In 1074–5, Omar Khayyam was commissioned by Sultan Malik-Shah to build an observatory at Isfahan and reform the Persian calendar. There was a panel of eight scholars working under the direction of Khayyam to make large-scale astronomical observations and revise the astronomical tables. Recalibrating the calendar fixed the first day of the year at the exact moment of the passing of the Sun's center across vernal equinox. This marks the beginning of spring or Nowrūz, a day in which the Sun enters the first degree of Aries before noon. The resulted calendar was named in Malik-Shah's honor as the Jalālī calendar, and was inaugurated on 15 March, 1079.. The observatory itself was disused after the death of Malik- Shah in 1092.
The 1st of Makaram marks the Winter Solstice (Uttarayanam) and the 1st of Karkaṭakam marks the summer solstice (Dakshinayanam) according to the Malayalam calendar. (According to the astronomical calendar the summer solstice is on June 21, and the winter solstice on December 21.) Chaitram 1 (usually coinciding with March 20) or Metam 1 (mostly coinciding with April 14, for 2019 it was on April 15th), both in the proximity of the date of the vernal equinox (March 21), mark the beginning of the new year in many traditional Indian calendars such as the Indian National calendar and the Tamil calendar. When the Government of Kerala adopted Kolla Varsham as the regional calendar, the 1st of Chingam, the month of the festival of Onam, was accepted as the Malayalam New Year instead.
The change arose from the realisation that the correct figure for the number of days in a year is not 365.25 (365 days 6 hours) as assumed by the Julian calendar but slightly less (c. 365.242 days): the Julian calendar has too many leap years. The consequence was that the basis for calculation of the date of Easter as decided in the 4th century had drifted from reality. The Gregorian calendar reform also dealt with the accumulated difference between these figures, between the years 325 and 1582 (1752 in the British Empire), by skipping 10 days (11 in the case of Great Britain, including its colonies and Ireland) to restore the date of the vernal equinox to approximately 21 March, the approximate date it occurred at the time of the First Council of Nicea in 325.
Each climate has different composition of these daylights and different cloud coverage, so daylighting strategies vary with site locations and climates. There is no direct sunlight on the polar- side wall (north-facing wall in the Northern Hemisphere and south-facing wall in the Southern Hemisphere) of a building from the autumnal equinox to the vernal equinox at latitudes north of the Tropic of Cancer and south of the Tropic of Capricorn. Traditionally, houses were designed with minimal windows on the polar side, but more and larger windows on the equatorial side (south- facing wall in the Northern Hemisphere and north-facing wall in the Southern Hemisphere). Equatorial-side windows receive at least some direct sunlight on any sunny day of the year (except in the tropics in summertime), so they are effective at daylighting areas of the house adjacent to the windows.
The Parsi community of India observe the new year using the Shahenshahi calendar which does not account for leap years, meaning this holiday has now moved by 200 days from its original day of the vernal equinox. In India the Parsi New Year is celebrated around 16-17 August. Tradition of Nowruz in Northern India dates back to the Mughal Empire; the festival was celebrated for 19 days with pomp and gaiety in the realm. However, it further goes back to the Parsi Zoroastrian community in Western India, who migrated to the Indian subcontinent from Persia during the Muslim conquest of Persia of 636–651 CE. In the Princely State of Hyderabad, Nowruz (Nauroz) was one of the four holidays where the Nizam would hold a public Darbar, along with the two official Islamic holidays and the sovereign's birthday.
Among the former, he thinks it the day on which a person married, and on which a son was born; among the latter, those days of public rejoicings appointed by a new emperor. Such days were devoted to general rejoicings and public sacrifices, and no one was allowed to show any symptoms of grief or sorrow. The Romans also celebrated hilaria as a feria stativa, on March 25, the seventh day before the Calends of April, in honor of Cybele, the mother of the gods; and it is probably to distinguish these hilaria from those mentioned above, that the Augustan HistoryAugustan History, "The Life of Severus Alexander", c37.6 calls them Hilaria Matris Deûm. The day of its celebration was the first after the vernal equinox, or the first day of the year which was longer than the night.
The discovery of precession is attributed to Hipparchus around 130 BC. Ptolemy quotes from Hipparchus' now lost work entitled "On the Displacement of the Solstitial and Equinoctial Points" in the seventh book of his 2nd century astronomical text, Almagest, where he describes the phenomenon of precession and estimates its value. Ptolemy clarified that the convention of Greek mathematical astronomy was to commence the zodiac from the point of the vernal equinox and to always refer to this point as "the first degree" of Aries. This is known as the "tropical zodiac" (from the Greek word trópos, turn) because its starting point revolves through the circle of background constellations over time. The principle of the vernal point acting as the first degree of the zodiac for Greek astronomers is also described in the 1st century BC astronomical text of Geminus of Rhodes.
Painted Wheel of the Year from the Museum of Witchcraft, Boscastle. In Wicca, the narrative of the Wheel of the Year traditionally centres on the sacred marriage of the God and the Goddess and the god/goddess duality. In this cycle, the God is perpetually born from the Goddess at Yule, grows in power at the vernal equinox (as does the Goddess, now in her maiden aspect), courts and impregnates the Goddess at Beltane, reaches his peak at the summer solstice, wanes in power at Lammas, passes into the underworld at Samhain (taking with him the fertility of the Goddess/Earth, who is now in her crone aspect) until he is once again born from Her mother/crone aspect at Yule. The Goddess, in turn, ages and rejuvenates endlessly with the seasons, being courted by and giving birth to the Horned God.
One of the sunset dates corresponding to the east–west axis of the late stages, including the last, is 4 April, which in the Julian calendar of the 16th century was equivalent to 25 March. In 1519, this was the last day of Tlacaxipehualiztli, that is, precisely the day of the feast of the month. Furthermore, 25 March, the Feast of the Annunciation, was in the Middle Ages commonly identified with the vernal equinox. Consequently, Motolinía did not refer to the astronomical equinox (the date of which would have hardly been known to a non-astronomer at that time), but rather only pointed out the correlation between the day of the Mexica festival, which in the last years before the invasion coincided with the solar phenomenon in the Templo Mayor, and the date in the Christian calendar that corresponded to the traditional day of spring equinox.
The Iranian calendar is an observational calendar that starts on the spring equinox and adds a single intercalated day to the last month (Esfand) once every four or five years; the first leap year occurs as the fifth year of the typical 33-year cycle and the remaining leap years occur every four years through the remainder of the 33-year cycle. This system has less periodic deviation or jitter from its mean year than the Gregorian calendar, and operates on the simple rule that the vernal equinox always falls in the 24-hour period ending at noon on New Year's Day. The 33-year period is not completely regular; every so often the 33-year cycle will be broken by a cycle of 29 years. A similar rule has been proposed to simplify the Gregorian calendar.Dr Jeremy Shears, President, British Astronomical Association, personal communication (JBAA 2015/022), 3 September 2015.
Jayasimha's Nasik plates are dated in the Abhira year 436 (685 AD) and record his grant of the village Dhondhaka on the occasion of the Vishuva or vernal equinox. Dhondhaka is identical with Dhondegaon, 12 miles north by west of Nasik. From two land-grants recently discovered at Anjaneri, a village near Trimbak in the Nasik district, we have come to know of a feudatory family which ruled over Northern Konkan and the Nasik district in the 7th and 8th centuries AD. This family claimed descent from Harishchandra, the famous legendary king of the Solar race. Svamichandra, who rose to power in the reign of Vikramaditya I, was the founder of this family, and flourished in circa 660 AD. Three generations of this family are known from the two sets of Anjaneri plates-Svamichandra, his son Simhavarman and the latter's son Bhogashakti alias Prithivichandra, who made the two grants.
The council decided in favour of celebrating the resurrection on the first Sunday after the first full moon following the vernal equinox, independently of the Bible's Hebrew Calendar, and authorized the Bishop of Alexandria (presumably using the Alexandrian calendar) to announce annually the exact date to his fellow bishops. The council was historically significant because it was the first effort to attain consensus in the church through an assembly representing all of Christendom. With the creation of the Nicene Creed, a precedent was established for subsequent general councils to create a statement of belief and canons which were intended to become guidelines for doctrinal orthodoxy and a source of unity for the whole of Christendom – a momentous event in the history of the Church and subsequent history of Europe. The council was opposed by the Arians, and Constantine tried to reconcile Arius with the Church.
It may have been adopted by Charlemagne for the Frankish Church as early as 782 from Alcuin, a follower of Bede. The Dionysian/Bedan computus remained in use in western Europe until the Gregorian calendar reform, and remains in use in most Eastern Churches, including the vast majority of Eastern Orthodox Churches and Non- Chalcedonian Churches. Having deviated from the Alexandrians during the 6th century, churches beyond the eastern frontier of the former Byzantine Empire, including the Assyrian Church of the East, now celebrate Easter on different dates from Eastern Orthodox Churches four times every 532 years. Apart from these churches on the eastern fringes of the Roman empire, by the tenth century all had adopted the Alexandrian Easter, which still placed the vernal equinox on 21 March, although Bede had already noted its drift in 725 it had drifted even further by the 16th century.
Working from the premise that the Giza complex encodes a message, the book begins with the fringe Sphinx water erosion hypothesis, evidence that the authors believe suggests that deep erosion patterns on the flanks of the Sphinx were caused by 1000 years of heavy rain. The authors go on to suggest, using computer simulations of the sky, that the pyramids, representing the three stars of Orion's Belt, along with associated causeways and alignments, constitute a record in stone of the celestial array at the vernal equinox in 10,500 BC. This moment, they contend, represents Zep Tepi, the "First Time," often referred to in the hieroglyphic record. They state that the initiation rituals of the Egyptian pharaohs replicate on Earth the sun's journey through the stars in this remote era, and they suggest that the "Hall of Records" of a lost civilisation may be located by treating the Giza Plateau as a template of these same ancient skies.
The primary source for the institution of Birkat Hachama is a Beraita mentioned in the Talmud:Bavli Berachot 59b The middle of this clause in the beraita (elided here) speaks of other astronomical phenomena, the interpretation of which is ambiguous. The Gemara clarifies when the 'turning point' (תקופה) mentioned in the beraita occurs: Next, the gemara explains the basis of the 28 years: This explanation provided by Abaye is based on a ruling of Shmuel also mentioned in the Talmud:Bavli Eruvin 56a > Shmuel stated: The vernal equinox occurs only at the beginning of one of the > four quarters of the day, either at the beginning of the day or at the > beginning of the night, or midday or midnight. The summer solstice only > occurs at either at the end of 1.5 or at the end of 7.5 hours of the day or > the night. The autumnal equinox only occurs at the end of 3 or 9 hours of > the day or the night.
Dionysius of Alexandria emphatically quoted mystical justifications for this very choice. 25 March was considered to be the anniversary of Creation itself. It was the first day of the year in the medieval Julian calendar and the nominal vernal equinox (it had been the actual equinox at the time when the Julian calendar was originally designed). Considering that Jesus was thought to have been conceived on that date, 25 March was recognized as the Feast of the Annunciation which had to be followed, nine months later, by the celebration of the birth of Christ, Christmas, on 25 December. There may have been more practical considerations for choosing 25 December. The choice would help substitute a major Christian holiday for the popular Pagan celebrations surrounding the Winter Solstice (Roman Sol Sticia, the three-day stasis when the sun would rise consecutively in its southernmost point before heading north, 21, 22 and 23 December.
Defeated centuries before by the first Librarian, Judson (Bob Newhart) and his Guardian, Charlene (Jane Curtin), he is resurrected when his sarcophagus is opened and embarks on a mission to release pure evil into the world, possessing many different people along the way. While they are trying to stop Apep, the Librarians' actions are closely monitored by General Cynthia Rockwell (Vanessa Williams) from a new secret government agency, called D.O.S.A. (Department of Statistical Anomalies). The fourth season does away with season-long story arcs in favor of stand-alone episodes, with three ongoing issues: Before the vernal equinox, Flynn and Eve must undertake a ceremony that will bind them to each other and to the Library, as Charlene and Judson did before them. They will become immortal and bind the Library to Earth, giving it a human connection and a human heart rather than the cold, implacable and dangerously self-centered attitude that would characterize it without that bond.
Right ascension (blue) and declination (green) as seen from outside the celestial sphere Various hour angles are depicted here. The symbol ♈ is the vernal equinox direction. Assuming the day of the year is the March equinox: the Sun lies toward the grey arrow, the star marked by a green arrow will appear to rise somewhere in the east about midnight (the Earth drawn from "above" turns anticlockwise). After the observer reaches the green arrow dawn comes over-powering (see blue sky Rayleigh scattering) the star's light about six hours before it sets on the western horizon. The Right ascension of the star is about 18h. 18h means it is a March early-hours star and in blue sky in the morning. If 12h RA, the star would be a March all-night star as opposite the March equinox. If 6h RA the star would be a March late-hours star, at its high (meridian) at dusk.
The Sun's placement upon the vernal equinox, which occurs annually around 21 March, defines the starting point for measurement, the first degree of which is historically known as the "first point of Aries". The first 30° along the ecliptic is nominally designated as the zodiac sign Aries, which no longer falls within the proximity of the constellation Aries since the effect of precession is to move the vernal point through the backdrop of visible constellations (it is currently located near the end of the constellation Pisces, having been within that constellation since the 2nd century AD). The subsequent 30° of the ecliptic is nominally designated the zodiac sign Taurus, and so on through the twelve signs of the zodiac so that each occupies 1/12th (30°) of the zodiac's great circle. Zodiac signs have never been used to determine the boundaries of astronomical constellations that lie in the vicinity of the zodiac, which are, and always have been, irregular in their size and shape.
Officially, Japan has 16 national, government-recognized holidays. Public holidays in Japan are regulated by the of 1948. Beginning in 2000, Japan implemented the Happy Monday System, which moved a number of national holidays to Monday in order to obtain a long weekend.

Modern scholar S. E. Hijmans, however, states that "While they were aware that pagans called this day the 'birthday' of Sol Invictus, this did not concern them and it did not play any role in their choice of date for Christmas." Moreover, Thomas J. Talley holds that the Roman Emperor Aurelian placed a festival of Sol Invictus on December 25 in order to compete with the growing rate of the Christian Church, which had already been celebrating Christmas on that date first. In the judgement of the Church of England Liturgical Commission, the History of Religions hypothesis has been challenged"Although this view is still very common, it has been seriously challenged" – Church of England Liturgical Commission, The Promise of His Glory: Services and Prayers for the Season from All Saints to Candlemas (Church House Publishing 1991 ) quoted in "The Date of Christmas and Epiphany" . by a view based on an old tradition, according to which the date of Christmas was fixed at nine months after March 25, the date of the vernal equinox, on which the Annunciation was celebrated.
The bull is Taurus, a constellation of the zodiac. In the astrological age that preceded the time of Hipparchus, the vernal equinox had taken place when the Sun was in the constellation of Taurus, and during that previous epoch the constellations of Canis Minor (The Dog), Hydra (The Snake), Corvus (The Raven), and Scorpius (The Scorpion)—that is, the constellations that correspond to the animals depicted in the tauroctony—all lay on the celestial equator (the location of which is shifted by the precession) and thus had privileged positions in the sky during that epoch. Mithras himself represents the constellation Perseus, which is located directly above Taurus the Bull: the same location occupied by Mithras in the tauroctony image. Mithras' killing of the Bull, by this reasoning, represented the power possessed by this new god to shift the entire cosmic structure, turning the cosmic sphere so that the location of the spring equinox left the constellation of Taurus (a transition symbolized by the killing of the Bull), and the Dog, Snake, Raven, and Scorpion likewise lost their privileged positions on the celestial equator.
Margaret Mead added her support for the equinox Earth Day, and in 1978 declared: > Earth Day is the first holy day which transcends all national borders, yet > preserves all geographical integrities, spans mountains and oceans and time > belts, and yet brings people all over the world into one resonating accord, > is devoted to the preservation of the harmony in nature and yet draws upon > the triumphs of technology, the measurement of time, and instantaneous > communication through space. > Earth Day draws on astronomical phenomena in a new way – which is also the > most ancient way – by using the Vernal Equinox, the time when the Sun > crosses the equator making the length of night and day equal in all parts of > the Earth. To this point in the annual calendar, EARTH DAY attaches no local > or divisive set of symbols, no statement of the truth or superiority of one > way of life over another.

They headed first to the Florida Everglades, then zigzagged northward following the advance of spring. Teale wrote about the adventure in North with the Spring. The book was followed by three others on the North American seasons: Journey Into Summer, Autumn Across America, and Wandering Through Winter, which won the Pulitzer Prize for General Non-Fiction in 1966.The Pulitzer Board, The Pulitzer Prize Winners 1966, accessed 3/2/2008 Teale served as president of the New York Entomological Society Official Website from 1944–1949 and the Brooklyn Entomological Society (later incorporated into the New York Entomological Society Official Website of the New York Entomological Society ) from 1949–1953. Teale worked as a co-writer for a segment titled "Vernal Equinox" on the March 20, 1955 episode of Omnibus, a TV-Radio Workshop of the Ford Foundation produced by Robert Saudek and hosted by Alistair Cooke on the CBS Television Network.United States Library of Congress Online Catalog, Author Search for Edwin Way Teale, accessed 3/2/2008 Teale became president of the Thoreau Society in 1958, the same year that Autumn Across America was presented to the White House Library.
The early Christian concepts of millenialism had ramifications far beyond strictly religious concerns during the centuries to come, as various theorists blended and enhanced them with ideas of utopia. In the wake of early millennial thinking, the Three Ages philosophy developed. The Italian monk and theologian Joachim of Fiore (died 1202) saw all of human history as a succession of three ages: # the Age of the Father (the Old Testament) # the Age of the Son (the New Testament) # the Age of the Holy Spirit (the age begun when Christ ascended into heaven, leaving the Paraclete, the third person of the Holy Trinity, to guide the faithful) It was believed that the Age of the Holy Spirit would begin at around 1260, and that from then on all believers would live as monks, mystically transfigured and full of praise for God, for a thousand years until Judgment Day would put an end to the history of our planet. Joachim of Fiore's divisions of historical time also highly influenced the New Age movement, which transformed the Three Ages philosophy into astrological terminology, relating the Northern-hemisphere vernal equinox to different constellations of the zodiac.
When Julius Caesar established the Julian calendar in 45 BC, he set 25 March as the date of the spring equinox; this was already the starting day of the year in the Persian and Indian calendars. Because the Julian year is longer than the tropical year by about 11.3 minutes on average (or 1 day in 128 years), the calendar "drifted" with respect to the two equinoxes – so that in 300 AD the spring equinox occurred on about 21 March, and by 1500 AD it had drifted backwards to 11 March. This drift induced Pope Gregory XIII to establish the modern Gregorian calendar. The Pope wanted to continue to conform with the edicts of the Council of Nicaea in 325 AD concerning the date of Easter, which means he wanted to move the vernal equinox to the date on which it fell at that time (21 March is the day allocated to it in the Easter table of the Julian calendar), and to maintain it at around that date in the future, which he achieved by reducing the number of leap years from 100 to 97 every 400 years.
