Equinox

Either of the two times each year when the sun crosses the equator and day and night are of equal length everywhere. It is said that an egg will stand on its end during the spring (vernal) equinox (about March 21). Depending on the shape of the egg, you may be able to stand it on its end other days of the year as well.
