Spring is one of the four seasons temperate zones, the transition from winter into summer. Astronomically, Spring begins with the vernal equinox (around March 20 in the Northern Hemisphere, and September 23 in the Southern Hemisphere), and ends with the summer solstice (around June 21 in the Northern Hemisphere and December 21 in the Southern Hemisphere). However, the “notion” of Spring can differ among cultures. In Chinese astronomy, for example, the vernal equinox instead marks the middle of spring, which begins around the time of Lichun (around February 4). In the Irish Calendar it is counted as the whole months of February, March and April. In meteorology, Spring is, by convention, counted as the whole months of March, April, and May in the Northern Hemisphere and September, October, and November in the Southern Hemisphere.
