In the northern hemisphere, it is about March 21, and in the Southern Hemisphere, the vernal (spring) equinox is about September 21. Those dates can fluctuate a day or two either way depending on the cycle of leap years.
You can look up the precise time of the equinoxes and solstices on the U.S. Naval Observatory's web site "Earth's Seasons" at the link below.
There is 1 day for each equinox: the vernal equinox in spring and the winter equinox in winter.
The "Vernal Equinox" is the beginning of "Spring" and the end of "Winter". The Autumnal Equinox is the beginning of "Autumn" or "Fall" and the end of "Summer". In the Northern Hemisphere, the Vernal Equinox is in March and the Autumnal Equinox in September each year.
It occurs in March, currently on March 20 each year. (the same date is the "vernal equinox" in the Northern Hemisphere)
The Vernal Equinox marks the beginning of spring in the Northern Hemisphere and occurs around March 20th each year. It is the point in Earth's orbit when the tilt of the Earth's axis is perpendicular to the Sun's rays, resulting in approximately equal lengths of day and night.
The date for the start of Spring each year is the Vernal Equinox, the day on which the overhead path of the Sun moves across the equator. The actual date depends on one's location north or south of the equator. The date will shift due to the 1/4 days by which the orbital year exceeds the calendar year.For the Northern Hemisphere, the Vernal Equinox is the "March equinox," which for most of the early 21st century (2001-2006 and 2008-2017) will be March 20. This is the Autumnal Equinox south of the equator.For the Southern Hemisphere, the Vernal Equinox is the "September equinox," which falls on September 23 (2010-2011) or September 22 (2012-2013).
3 Twice. On the Autumnal equinox and on the Vernal equinox.
It is called an equinox. In the spring it is known as the Vernal Equinox while in the autumn it is known as the Autumnal Equinox. Both take place around the 21st of March/September, but the date varies slightly each year.
Easter Sunday falls AFTER the first full moon AFTER the Vernal Equinox. While the date for the Vernal Equinox is the same every year, the phases of the moon do not fall on the same date. This is why Easter Sunday is a different date each year. The earliest possible date for Easter Sunday is March 22. The latest possible date is April 25. This year (2011) Easter Sunday falls on April 24.
Pisces typically ends and Aries usually begins around March 20 or 21 each year, marking the transition from Pisces to Aries with the arrival of the vernal equinox. The exact date can vary slightly each year due to the timing of the equinox, but generally, Aries season starts on March 21.
The ascending node (of the sun's path) and the Vernal Equinox are both the same point on the map of the stars. As seen from Earth, the sun appears to reach and pass that point on March 21.
There are two days each year when the day and night are of equal duration, known as the equinoxes. The vernal (spring) equinox occurs around March 21st, marking the beginning of spring in the Northern Hemisphere, while the autumnal equinox occurs around September 22nd, marking the beginning of autumn.
Easter Sunday in 2023 was celebrated on April 9th. The date of Easter varies each year, as it is determined by the first Sunday after the first full moon following the vernal equinox.
