1, no. Beginning of winter is not a winter solstice, but two different solar terms. The solar term in beginning of winter means the official entry into winter, which comes around165438+10.7 every year, and the sun revolves around the longitude of 225. The soul of the sun rises in winter, which is the beginning of the traditional calendar. Every year around 65438+February 22nd, the sun rotates 270 degrees around the yellow meridian.

2. The difference between beginning of winter and the winter solstice.

(1) beginning of winter time is different, and the time point is between the Gregorian calendar165438+1October 7-8, that is, the sun is located at 225. The winter solstice usually falls on February 2 1 or 65438+February 22.

(2) With different meanings, beginning of winter is also established, which means that winter has started from now on. Winter means the end, and some countries that want to collect crops after harvest take beginning of winter as the beginning of winter. The 46 days after beginning of winter is the winter solstice, which is not "arrival" but "extreme". As the saying goes, the day is over.

(3) The climate is different. In ancient China, beginning of winter was divided into three periods every five days: "Ice began with water; The second waiting place began to freeze; Waiting for the flood is a cockroach. " Winter not only represents the coming of winter, but completely speaking, beginning of winter means the beginning of winter, the gathering of all things, and the shelter from the cold. Astronomy regards the winter solstice as the beginning of winter, and the winter solstice is the shortest day in a year. During the winter solstice, the average temperature in Xiyuan is generally below 0℃, while it is only about 6℃ to 8℃ in the south. In ancient China, the winter solstice was divided into three stages: "Earthworm knot; Two-phase angular solution; Waiting for the spring to gush out. "
