When does Autmn end and Winter begin?

Answer 2

Astronomically, some Western countries consider autumn to begin with the autumnal equinox (around September 23) in the Northern hemisphere, and the vernal equinox (March 21) in the southern hemisphere), ending with the winter solstice (around December 21 in the Northern hemisphere) and the summer solstice (June 21) in the Southern hemisphere). Such conventions are by no means universal, however. An exception to these definitions is found in the Irish Calendar which still follows the Celtic cycle, where Autumn is counted as the whole months of August, September and October. In Chinese astronomy, the autumnal equinox marks the middle of autumn, which is deemed to have begun around the time of Liqiu (around August 7).

On the other hand, meteorologists count the entire months of March, April and May in the Southern hemisphere, and September, October and November in the Northern hemisphere as autumn.

Albeit the days begin to shorten after the summer solstice, it is usually in September (Northern Hemisphere) or March (Southern Hemisphere) when twilight becomes noticeably shorter and the change more abrupt in comparison with the more lingering ones of summer.

Answer 3

The first day of winter begins Dec. 22. For future reference, check a calendar.

Answer 4

Winter begins on the Winter Solstice, which is on the 21st or 22nd of December, depending on the year. I don't know which it is this year.
