The winter solstice, also known as the southern solstice, winter festival, sub-year, etc. It has both natural and humanistic connotations. It is not only an important solar term among the 24 solar terms, but also a traditional ancestor worship festival in China. The winter solstice is one of the four seasons and eight festivals, and it is considered as a big festival in winter. In ancient times, there was a saying that the winter solstice was as big as a year. Due to different regions, the customs of winter solstice are different in content or details. In southern China, customs are different. In northern China, it is a custom to eat jiaozi from winter to Sunday every year.

The winter solstice is the 22nd of the 24 solar terms. The solar calendar reaches 270 degrees, and it intersects on the 23rd day of the Gregorian calendar (65438+February, 2 1) every year. The solstice in winter is the southernmost point of direct sunlight.

Astronomical calendar

As an important node of the 24 solar terms in China, the winter solstice is the day with the shortest day and the longest night in the northern equator of the earth. The solstice in winter is the limit of the sun's southward travel. On this day, the height of the sun in the northern hemisphere is the smallest. 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.

From winter to around, the earth is located near the perihelion, and its running speed is slightly faster, resulting in that the time for the sun to shine directly into the southern hemisphere is about 8 days shorter than that in the northern hemisphere, so the winter in the northern hemisphere is slightly shorter than that in summer.
