The meaning of winter solstice solar terms

The winter solstice is the 22nd of the 24 solar terms. The annual Gregorian calendar is 65438+February 2 1-23.

The solstice in winter is the limit of the sun's southward travel, and the sun shines directly on the tropic of Capricorn. On this day, the height of the sun in the northern hemisphere is the smallest, and the sun is most biased towards the northern hemisphere. The solstice in winter is the turning point of the sun. After this day, it will go back. The direct point of the sun will move northward from the Tropic of Capricorn (23 26' s), and the northern hemisphere (China is located in the northern hemisphere) will increase day by day. In all parts of the northern hemisphere, the winter solstice has the shortest day and the longest night. The winter solstice marks the beginning of the cold season, and people begin to count nine to calculate the cold days.
