| | On Spring Equinox, Day and Night Equal in Name Only (Site not responding. Last check: 2007-10-07) |
 | | In the Northern Hemisphere spring officially begins on this Saturday, the vernal equinox, at 1:49 a.m. |
 | | The day of light and dark equality always happens before the spring and after the fall equinoxes, according Geoff Chester, a public affairs specialist with the U.S. Naval Observatory in Washington, D.C. "Exactly when it happens depends on where you are located on the surface of the Earth," he said. |
 | | The equinox, however, is when the center of the sun crosses the Equator. |
