Spring is one of the four seasons of temperate zones, the transition from winter into summer. Astronomically, some Western countries consider spring to begin with the spring 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). Such conventions are by no means universal, however. 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, it is (also by convention) instead counted as the whole months of March, April, and May in the Northern Hemisphere and September, October, and November in the Southern Hemisphere.

The Vernal equinox is the time at which the sun appears to cross the celestial equator, on its way from the southern to the northern celestial hemisphere.
On Earth's North hemisphere, in most western cultures, the day of the equinox (around March 21) marks the official calendar start of Spring.
On Earth's South hemisphere (e.g., in Australia), the day on which the Sun crosses the celestial equator going south is the day they consider the start of Spring (around September 21).
In many Asian cultures, the Start of Spring is (or used to be) halfway between the winter solstice (around December 21) and Vernal Equinox. The Asian months are based on the Moon, so they do not match the ones used by western cultures.
Spring finishes halfway between Vernal Equinox and the June solstice.
In this manner, the day of Vernal Equinox is roughly the middle of the Season.
