Spring is one of the four temperate seasons, the transition period between winter and summer. Spring and "springtime" refer to the season, and broadly to ideas of rebirth, renewal and regrowth. The specific definition of the exact timing of "spring" varies according to local climate, cultures and customs. At the spring equinox, days are close to 12 hours long with day length increasing as the season progresses. Sunday, March 20, 2011 marks the vernal equinox, and what many people in the Northern Hemisphere -- particularly the U.S. -- refer to as the first day of spring. At 7:21 p.m. EST astronomical spring begins in the Northern Hemisphere as defined by International Astronomical Union, though it will be the beginning of fall for those in the Southern Hemisphere. On the vernal equinox, day and night will be nearly identical in length -- 12 hours each -- at the equatorial plane.
