Spring is one of the four conventional temperate seasons, following winter and preceding summer. 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. Spring and "springtime" refer to the season, and also to ideas of rebirth, rejuvenation, renewal, resurrection, and regrowth.

According to my wall calendar, today is the first day of Spring.
