Since the Celtic year was based on both lunar and solar cycles, it is most likely that the holiday would be celebrated on the full moon nearest the midpoint between the winter solstice and vernal equinox, or when the primroses, dandelions, or other spring flowers rise up through the snow, or when the sun aligned with the passage tombs in the pre-Celtic megaliths.

As a result, the calendar year gained about three days every four centuries compared to observed equinox times and the seasons.

The vernal equinox year is about days long, measured in ephemeris time.

But in 8, 000 years, the length of the vernal equinox year will have changed by an amount that cannot be accurately predicted.

There are some that believe the Thelemic New Year falls on either 19, 20 or 21 March, depending on the vernal equinox, this is The Feast for the Equinox of the Gods which is held on the vernal equinox of each year to commemorate the founding of Thelema in 1904.

The reason for the reform was that the average length of the year in the Julian calendar was too long – it treated each year as 365 days, 6 hours in length, whereas calculations showed that the actual mean length of a year is slightly less ( 365 days, 5 hours and 49 minutes ) As a result, the date of the actual vernal equinox had slowly ( over the course of 13 centuries ) slipped to 10 March, while the computus ( calculation ) of the date of Easter still followed the traditional date of 21 March.

The passage itself, in a number of notable instances, is aligned in such a way that the sun shines into the passage at a significant point in the year, for example at sunrise on the winter solstice or at sunset on the equinox.

The present vernal equinox year, however, is about 12 seconds longer, in terms of mean solar days.

In the pagan wheel of the year the spring equinox is the time of Ostara and the autumn equinox is that of Mabon.

In the USA ( and sometimes in Britain ) the season is regarded as beginning at the solstice and ending on the following equinox – in the Northern Hemisphere, depending on the year, this corresponds to the period between 21 or 22 December and 20 or 21 March.

The Gregorian calendar attempts to keep the vernal equinox on or soon before March 21, hence it follows the vernal equinox year.

It is estimated that, by the year 4000, the vernal equinox will fall back by one day in the Gregorian calendar, not because of this difference, but because of the slowing down of the Earth's rotation and the associated lengthening of the sidereal day.

The name " equinox " is derived from the Latin aequus ( equal ) and nox ( night ), because around the equinox, the night and day have approximately equal length.

Sunrise is just before the March equinox ( around March 19 ); the sun then takes three months to reach its highest point of near 23½ ° elevation at the summer solstice ( around June 21 ), after which time it begins to sink, reaching sunset just after the September equinox ( around September 24 ).

solstice and equinox, so the mid-summer festival would fall considerably later than summer solstice, around 1 August ( Lughnasadh ).

The Babylonian star catalogues name them MUL. MUL or " star of stars ", and they head the list of stars along the ecliptic, reflecting the fact that they were close to the point of vernal equinox around the 23rd century BC.

If the position of the earth in its orbit around the sun is reckoned with respect to the equinox, the point at which the orbit crosses the celestial equator, then its dates accurately indicate the seasons, that is, they are synchronized with the declination of the sun.

The majority of astrologers study tropical astrology, involving planetary positions referenced to the vernal ( spring ) equinox position along the ecliptic ( the equinox being the center of Earth's rotational plane and Earth's orbital plane around the Sun ).

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.

In particular, there is a short period around the autumnal equinox when most of the objects can be seen.
