What day is the end of winter?

Answer 1

Astronomically, the winter solstice, being the day of the year which has fewest hours of daylight, ought to be the middle of the season, but temperature lag means that the coldest period normally follows the solstice, so the season is sometimes regarded (in the USA and England) as beginning at the solstice and ending on the following equinox. In theNorthern Hemisphere, depending on the year, this corresponds to the period between 21 or 22 December and 20 or 21 March. Meteorologists in the UK consider winter to be the three coldest months of December, January and February

Answer 2

March (in the northern hemisphere), September (in the southern hemisphere).
