Countdown to astronomical* Spring
 Vernal Equinox begins March 20th at 2:46pm   GMT  
 
* Astronomers base the seasons around the equinox when day and night are of approximately equal length (about 22 September and 20 March). Meteorologists use a temperature-based system to determine the season, with the warmest months of the year (June to August) as summer and all other seasons in 3 month blocks around that date. A pagan based tradition has spring starting on the 1st February, and all other seasons in 3 month blocks before or after that.
