Is 65438+February 22nd the winter solstice?

65438+February 22nd is the "winter solstice", which is the longest night and the shortest day in the northern hemisphere. This sentence is correct.

In winter solstice, although the sun is low and the days are short, the temperature in winter solstice is not the lowest in meteorology. In fact, because there is still "accumulated heat" on the surface, it is usually not very cold before the winter solstice, and the real cold is after the winter solstice.

Because of the huge climate difference in China, this climatic winter is obviously late for most parts of China. The winter solstice marks the beginning of the cold season, and people begin to count nine to calculate the cold days.

From winter to around, the earth is located near the perihelion, and its running speed is slightly faster, resulting in that the time of direct sunlight in the southern hemisphere is about 8 days shorter than that in the northern hemisphere in a year, so the winter in the northern hemisphere is slightly shorter than that in summer.

Extended data:

Every winter solstice, no matter the rich or the poor in northern China, jiaozi is indispensable. Jiaozi eaten in the winter solstice and jiaozi eaten in the Spring Festival have different meanings. Jiaozi eaten during the Spring Festival is at the junction of the new year and the old year, and jiaozi means "making friends" when you are old. Eating jiaozi during the Spring Festival is considered lucky.

Jiaozi, which is eaten from the winter solstice, means to drive away the cold. According to legend, Zhang Zhongjing, a medical sage, saw the frozen people when he retired in his later years, so he wrapped mutton, some cold-dispelling herbs and dough in his ears and made the medicine of "Joule Decoction for Eliminating Cold" for the people to eat. Later, every winter solstice, people imitate it and eat it.
