An equinox is an astronomical event in which the plane of the Earth's equator passes through the center of the Sun. This occurs twice a year, once in the spring and then again in the fall.
On an equinox, day and night are of approximately equal duration all over the planet. They are not exactly equal, however, due to the angular size of the sun and atmospheric refraction.
3. Why is this year's Vernal Equinox so early?

Our calendar, on the other hand, has an even 365 days in a common year and 366 days in a leap year.
