March 20, 2010
Equinox Means "Equal Night," because the sun is positioned above the equator, day and night are about equal in length all over the world during the equinoxes. On March 20, 2010, at precisely 1:32 P.M. EDT, the Sun will cross directly over the Earth's equator. This moment is known as the vernal equinox in the Northern Hemisphere. For the Southern Hemisphere, this is the moment of the autumnal equinox.
