The northern spring begins at 6:45 a.m. today as the sun crosses the celestial equator into the northern hemisphere. Many still think the equinox occurs March 21, but the last time that happened in our time zone was in 1979. The next will be in 2103, says Geoff Chester of the U.S. Naval Observatory. Spring arrives on the 20th until 2020, when a March 19 equinox becomes possible.
