Welcome to spring!
Last Friday, March 20, 2009, at precisely 7:44 A.M. EDT, the Sun crossed directly over the Earth’s equator. This moment is known as the vernal equinox in the Northern Hemisphere. If you lived in the Southern Hemisphere, this would be the autumnal equinox.
Translated literally, equinox means “equal night”. Because the sun is positioned above the equator, day and night are about equal in length all over the world.
Remember! you can always balance an egg any day!
