Is the winter solstice the shortest day and the longest night in a year?

Yes, the winter solstice is the shortest day in a year. The winter solstice in the northern hemisphere is generally between 65438+February 2 1 and 65438+February 23. In the lunar calendar, 1 1 month is the month of winter solstice.

The winter solstice is the first day of nine cold days. As the saying goes, "winter solstice is nine years old", it begins to count nine days, and the ninth day is regarded as nine days. After 998 1 year, winter has passed, which is called number nine. Therefore, there is a folk "Nine-Nine Cold Relieving Map" to record the process of counting nine. In ancient times, the solar terms from the winter solstice were the starting point for calculating the 24 solar terms, as well as the starting point and end point for calculating the year.

According to Xiongxian Annals in the early years of the Republic of China, traditional China people would erect eight-foot table trees in winter solstice to test the flood and drought in the coming year. There was also a criterion for judging flood and drought in the Han Dynasty, that is, "water comes when you enter, and drought comes when you retreat."

In addition, China people will observe the changes of clouds and gases at sunrise and sunset from winter to day, and judge the weather during the Spring Festival by predicting the wind, rain and sunshine. Zhejiang agricultural proverb says, "The winter solstice is sunny and the year is rotten, and the winter solstice is sunny and the New Year is sloppy." It means that there will be no rain and snow on the solstice in winter, but it will rain and snow in the Spring Festival, making the road slippery and muddy; or vice versa, Dallas to the auditorium
