Which of the 24 solar terms is the winter solstice?

The winter solstice is the 22nd solar term in the "24 solar terms", and the solar calendar reaches 270 degrees. Every year, the festival is held on 65438+February 2 1-23 in the Gregorian calendar. The winter solstice is the limit of the sun's southward travel, and the height of the sun in the northern hemisphere is the smallest on this day.

On the solstice of winter, the sun shines directly on the tropic of Capricorn, and the sun is most inclined to the northern hemisphere. The solstice in winter is the turning point of the sun's southward movement. After this day, I went back, and the direct point of the sun began to move northward from the Tropic of Capricorn (23 26' s), and the daytime in the northern hemisphere (China is located in the northern hemisphere) increased day by day.

In all parts of the northern hemisphere, the winter solstice has the shortest day and the longest night. The farther north, the shorter the day. Although the days from winter solstice are short, the temperature from winter solstice is not the lowest; It won't be very cold before the winter solstice, because there is still "accumulated heat" on the surface, and the real winter is after the winter solstice;

Due to the great differences in climate in different parts of China, the climatic characteristics of this day are obviously late for most parts of China. The winter solstice marks the beginning of the cold season, and people begin to count to nine to calculate the cold weather (folk proverb: "The summer solstice is the third watch, and the winter solstice is the ninth watch").
