Which dynasty is the origin and custom of the winter solstice?

The winter solstice originated in the Han Dynasty. This was the first dynasty to regard the winter solstice as a festival. During the Tang and Song Dynasties, winter solstice prevailed and has been passed down to this day. According to the records in the Book of the Later Han Dynasty, the whole court should have a holiday from winter to around, and shops and hotels should be closed for rest.

The winter solstice is an important node in the 24 solar terms. After the solstice in winter, it entered the "cold weather". The ancients believed that the winter solstice was a day of transformation between Yin and Yang, a blessing from God, and a festive day, so the winter solstice was as big as a year.

In the past, the winter solstice was still a day of sacrifice. It is said that after the Song Dynasty, the solstice in winter gradually became a day to worship ancestors and gods. In the Tang and Song Dynasties, the solstice in winter was a day to worship heaven and earth and ancestors. During the Ming and Qing Dynasties, emperors held sacrificial ceremonies on the solstice of winter.

Calendar phenomenon

The date of winter solstice in 2020 is 65438+February 2 1, and the date of winter solstice in 2026 is also 65438+February 2 1. The date of winter solstice for two consecutive years is 65438+February 2 1, which is a very rare calendar phenomenon. According to statistics, this strange calendar phenomenon last appeared in 1896 and 1897, that is, 124 years ago.

The main reason for this calendar phenomenon is that the length of the current solar calendar is inconsistent with the length of the tropic year.

According to statistics, from 2056, for three consecutive years (2056-2058), the date of winter solstice is 65438+February 2 1. Stranger still, since 2088, the date of winter solstice has been 12 (2088- 1999), and now it is 12,21. This calendar phenomenon has never been experienced by anyone in the world today.
