Meteorologists and climatologists use a simpler system based on and full months for record-keeping:
Starts with the Vernal Equinox (March 20/21)Spring is defined by thawing ice, blooming flowers, and increasing daylight. In many cultures, March is seen as the "bridge" month where winter’s grip finally loosens. Summer: June, July, August Meteorological: June 1 – August 31
These are based on the annual temperature cycle and the Gregorian calendar. They divide the year into four consistent three-month periods, making it easier for scientists to track climate data.
