Who heralds the beginning of winter, the solstice of winter or the beginning of winter?

There are two solar terms in winter, one is beginning of winter, and the other is the winter solstice. Many friends will confuse the winter solstice with the solar terms in beginning of winter. Generally speaking, beginning of winter is in 165438+ 10, and the winter solstice is in 65438+February.

As the first solar term in winter, it starts around165438+1October 8 every year, when the sun reaches 225. Because of the latitude difference between north and south in China, the real winter is not always based on "beginning of winter", but on the continuous temperature below 10℃. But in the traditional concept, "winter" means "end", which means ending. After beginning of winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon. China regards beginning of winter as the beginning of winter.

China is an important solar term in the lunar calendar. The winter solstice is commonly known as "winter festival", "long festival" and "year-divided". It is the earliest of the 24 solar terms. On the winter solstice, the direct position of the sun on the ground reaches the southernmost point of the year and almost directly reaches the Tropic of Capricorn (23 26' south latitude). During the winter solstice, the northern hemisphere gets the least sunshine, 50% less than the southern hemisphere. The days in the northern hemisphere are the shortest, and the farther north they are, the shorter they are.

China has a vast territory, and the north and south span dozens of latitudes, so there is a temperature difference between the north and the south. However, after winter, the temperature difference between the north and the south widened. Many places in the north have been dry, everything is withered, and the cold is pressing; South China is still green mountains and green waters, birds and flowers, warm and pleasant.

The solstice in winter is the shortest day in a year. Climatically, during the winter solstice, the average temperature in the northwest plateau is generally below 0℃, and the southern region is only about 6℃ to 8℃. In addition, the winter solstice begins to count to nine, and the winter solstice becomes the first day to count to nine.
