The Vernal Equinox – March 20, 2015
The word equinox is derived from the Latin words meaning “equal night.” All over the world, days and nights are approximately equal. Today, the Sun rises exactly in the east and sets exactly in the west.
At the equinoxes, the tilt of Earth relative to the Sun is zero, which means that Earth’s axis neither points toward nor away from the Sun. (However, the tilt of Earth relative to its plane of orbit, called the ecliptic plane, is always about 23.5 degrees.)
