Is the solstice long in summer or short in winter?

The solstice in winter is the shortest day.

According to China Military Network, the solar term from winter solstice originated in the Spring and Autumn Period, flourished in the Tang and Song Dynasties, and has been in use ever since. In ancient China, the earth was used to observe the sun, and the time of winter solstice was generally between 65438+February 2 1 ~ 23 in Gregorian calendar every year. The winter solstice is the year with the shortest day and the longest night in the northern hemisphere. After the winter solstice, the days will gradually become longer, and the climate in various places will enter the coldest stage, which is often called "entering the ninth".

The time point in beginning of winter is between July and August of Gregorian calendar165438+1October, that is, the sun is located at 225. At this time, the earth is located at declination-16 19'. Before and after winter, the precipitation in most areas of China decreased obviously, the land in the north froze, agricultural and forestry crops entered the wintering period, and the "Sanqiu" in Jianghuai area was coming to an end. It is necessary to plant late winter wheat and transplant rape in the south of the Yangtze River, and the southern region is the best time to plant wheat. In addition, after winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon. At this time, the air is dry and the soil moisture is low, so pay attention to fire prevention.

In China, especially in the north, many festivals and solar terms will eat jiaozi, such as Fu Tou, beginning of winter and New Year's Eve in dog days. Beginning of winter's eating of jiaozi originated from the saying that it is the time of copulation, because people think that beginning of winter is the turn of autumn and winter, and copulation is homophonic with jiaozi, so beginning of winter should eat jiaozi on this day. Beginning of winter is a tonic solar term, as the saying goes, "beginning of winter fills the winter, but its mouth is empty". Therefore, the diet after beginning of winter should focus on keeping warm, which can warm the body, dispel cold, enhance resistance and reduce diseases.

There is also the custom of eating jiaozi on the solstice in winter. According to Zhengzhou Evening News, there has always been a saying in northern China, "When winter solstice comes, you will eat jiaozi", so the custom of winter solstice in northern China is to eat jiaozi. Most southern regions eat glutinous rice balls in winter solstice, and some southern regions drink mutton soup in winter solstice to drive away the cold. In some areas of Jiangnan water town, the whole family will get together to eat red beans and glutinous rice on the night of winter solstice.
