The date for the start of Spring each year is the Vernal Equinox, the day 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. The date will shift due to the 1/4 days by which the orbital year exceeds the calendar year.For the Northern Hemisphere, the Vernal Equinox is the "March equinox," which for most of the early 21st century (2001-2006 and 2008-2017) will be March 20. This is the Autumnal Equinox south of the equator.For the Southern Hemisphere, the Vernal Equinox is the "September equinox," which falls on September 23 (2010-2011) or September 22 (2012-2013).
