Spring Equinox - March 20, 2007
Spring is here! Or Vernal Equinox, or "Equal Night". This means the days will start to get longer after this, and the nights shorter. Because the sun will pass directly over the equator, days and nights will be of equal length all over the world. There are many holidays and celebrations associated with equinoxes - Easter is designated as the first Sunday after the first full moon following the vernal equinox.
