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.

When is the first day of spring?

The date for the start of the astronomical spring season each year is called the Vernal Equinox, one of two days 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, and 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).The first climatological day of spring, as mandated by the World Meteorological Organization, is March 1 every year in the northern hemisphere and September 1 every year in the southern hemisphere.Canada, the USA, and some European countries customarily observe the astronomical date (ca. March 20-21/ca. September 22-23) while Australia, New Zealand, and some other European countries follow the climatological date (March 1/September 1). Customary dates are often declared "official" by the mass media although no legal basis exists for this designation. Preferences for the astronomical or climatological dates vary in other countries. Lunar dates are used across much of east Asia to determine the beginning of spring.The ecological beginning of spring (vernal season) has no fixed dates but is marked locally by the beginning of the growing season for most plants when the local mean daily temperature reaches 6 degrees C/42 degrees F. Many ecologists also recognize a pre-spring (prevernal) season that precedes spring. Pre-spring is a transitional time at the end of winter when only the hardiest plants like the crocus begin to bloom.Tropical regions of the Earth do not have a spring season.

If there is a lunar eclipse on the vernal equinox is the moon above the ecliptic?

During a lunar eclipse, the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall on the Moon. The vernal equinox marks the time when the Sun crosses the celestial equator, and the ecliptic is the apparent path of the Sun across the sky. If a lunar eclipse occurs on the vernal equinox, the Moon would be aligned with the ecliptic, meaning it would not be above it, but rather in the same plane as the ecliptic.


Why was Easter early this year?

Easter was early this year because it is determined by the lunar calendar, which follows the cycles of the moon. The date of Easter is set as the first Sunday after the first full moon that occurs on or after the vernal equinox, which is why it can vary from year to year.

I do not go by the number of days but in a 360 degree year there are 60 degrees between the Autumnal Equinox and the Vernal Equinox. or you must count the days in each month in a sidereal calender instead of the lunar one that I go by for a few reasons/keeping track of my cycle for one reason and my sanity for another. > Just ME<
