The seasons are considered to start at the equinoxes and solstices in an "astronomical" sense. However, because the seasonal lag is less than 1/8 of a year (except near large bodies of water), the "meteorological" start of the season precedes, by about three weeks, the start of the "astronomical" season. This time differential keeps the "meteorological" definition more symmetrically centered around the warmest part of the year than the "astronomical one" is. Today, the "meteorological" definition is gaining momentum, but the "astronomical" definition is more frequent, and most people today still regard it as "official". In fact, the equinoxes and solstices of the astronomical seasons are considered to be the naturally official beginnings of seasons.
