According to the astronomical calendar, winter begins around December 21st. For meteorologists and climatologists, winter has already begun on December 1st, and the season lasts exactly three calendar months.

Solstice: the time or date (twice each year) at which the sun reaches its maximum or minimum declination, marked by the longest and shortest days (about 21 June and 21or22 December)
