What is special about March 20th?

Its a Spring Equinox of course!!  (the first day of spring)
Equinox means equal and a spring equinox means that the hours of day time and hours of night time are close to equal. (not exactly equal but close)
We should enjoy around 12 hours of sunlight and 12 hours of darkness on March 20th.
