Vernal Equinox Facts
The term equinox has been derived from the Latin word Equinoxium. It means ‘equality between day and night’. There are two equinoxes, March Equinox and September Equinox. The Equinox that occurs in March is known as Vernal Equinox in Northern Hemisphere and the Autumnal Equinox in Southern Hemisphere. The Equinox that occurs in September is Vernal (spring) equinox of Southern Hemisphere and Autumnal (fall) Equinox of Northern Hemisphere.
