What is Equinox?

March equinox is the time span when the Sun seems to move from the Southern hemisphere of the Earth to the Northern hemisphere. March equinox is known as the Vernal equinox while in the Northern hemisphere while it is known as Autumnal equinox in the Southern hemisphere.

According to the Gregorian calendar, the Equinox can happen in between 19 March to 21 March. The time when the equinox happens postpones every year by 5 hours and 49 minutes in a non-leap year, while in a leap year, the time “resets” by 18 hours and 11 minutes. The following table shows the date and time  when the Equinox happened in March from 2010 and will do so until 2020.
