Difference between Vernal Equinox and Tropical Year

VERNAL EQUINOX vs TROPICAL YEAR: NOUN

The point where the ecliptic intersects the celestial equator at that time
The moment when the sun appears to cross the celestial equator, heading northward
The moment at which the sun passes through this point on or about March 21, marking the beginning of spring in the Northern Hemisphere and autumn in the Southern Hemisphere.
One of two points at which the ecliptic intersects the celestial equator. At the vernal equinox, the sun is moving along the ecliptic in a northeasterly direction.
March 21
(astronomy) the equinoctial point that lies in the constellation of Pisces

A vernal equinox year, the time between two successive vernal equinoxes.
The time that it takes for the Sun to return to the same position along the ecliptic, as viewed from the Earth, especially:
The time for the earth to make one revolution around the sun, measured between two vernal equinoxes

On the vernal equinox, the sun rises directly over the central tower at Angkor Wat in Cambodia.
For people in the southern hemisphere, winter solstice occurs in June, vernal equinox in September, etc.
Easter day is, briefly, the first Sunday after the full moon following the vernal equinox.
Astronomically, this is the period between the winter solstice and the vernal equinox.
The year begins at the exact moment of the vernal equinox.
Thus, Easter is based on the vernal equinox even today by the Catholic church.
Passover, not the new moon of Abib, historically fell after the vernal equinox.
For their harvest was between Easterand Whitsunday, and began about a month after the vernal Equinox.

Autumn and Vernal Equinox calculates the time and date of the fall or spring equinox of the current year.

It did not properly reflect the actual time it takes the Earth to revolve once around the Sun, known as a tropical year.
Currently the time between two vernal equinoxes is slightly greater than the tropical year.
Our calendar year is linked to the tropical year as measured between two March equinoxes, as originally established by Caesar and Sosigenes.
The tropical year, also called the mean solar year, is dependent on the seasons.
