The date for the start of the Spring season each year is called the Vernal Equinox, one of two days on which the overhead path of the Sun moves across the equator. The actual date depends on one's location north or south of the equator, and will shift due to the 1/4 days by which the orbital year exceeds the calendar year.

2011 -

March equinox (spring begins in the northern hemisphere): March 20, 2011 (23:21 UTC)

September equinox (spring begins in the southern hemisphere): September 23, 2011 (09:04 UTC)

2012 -

March equinox (spring begins in the northern hemisphere): March 20, 2012 (05:14 UTC)

September equinox (spring begins in the southern hemisphere): September 22, 2012 (14:49 UTC)
