When does winter start and end?

Winter is from February 65438 to February of the following year.

In winter, the climate is cold, with yin flourishing and yang declining. There are actually many ways to divide winter time. The first thing to know is that the winter time in the northern hemisphere is opposite to that in the southern hemisphere. Secondly, winter can be divided into astronomy, temperature and even solar terms. China used to refer to the three months from beginning of winter to beginning of spring in winter, and also referred to the "October, November (winter) and December (wax) months" of the lunar calendar. The time in the northern and southern hemispheres is different.

According to the meteorological significance, in the temperate and cold regions of the southern hemisphere, the winters are in June, July and August (or from May 2/kloc-0 to August 22 according to the constellation standard), and in the temperate and cold regions of the northern hemisphere, the winters are in 12, 1 and February (or according to the constellation standard 16544)
