Tuesday, March 20, 2018: Vernal Equinox

The Vernal Equinox falls on Tuesday, March 20, 2018 at 12:15 P.M. EDT.

The word equinox is derived from the Latin words meaning “equal night.” The vernal, or spring, equinox is the point at which the Sun appears to cross the celestial equator from south to north, signaling the beginning of nature’s renewal in the Northern Hemisphere.
