What is the nickname of winter solstice?

Winter solstice is called sub-year, winter festival, small solstice, big winter and small year.

The winter solstice is the 22nd solar term in the "24 solar terms", and the solar calendar reaches 270 degrees. Every year, the festival is held on 65438+February 2 1-23 in the Gregorian calendar. The solstice in winter is the extreme point of direct sunlight spreading to the south. From winter to the sun, the sun shines directly on the Tropic of Capricorn, and the sun is most inclined to the northern hemisphere, and the solar altitude angle is the smallest. In all parts of the northern hemisphere, the days are the shortest and the nights are the longest.

The solstice in winter is also the turning point of direct sunlight returning to the north. After this day, it went back, and the direct sunlight began to move northward from the Tropic of Capricorn (23 26' s), and the sunlight in the northern hemisphere (China is located in the northern hemisphere) increased day by day.

Phenological phenomena in winter from solstice;

Some ancient Chinese literary works divided the winter solstice into three stages: "First, earthworm knot;": Second, wait for the elk horn to solve; Waiting for the spring to gush out. " It means that the earthworm is still curled up in the soil, and the elk feels the yin gradually retreating and falling off its horns.

Since the direct point of the sun returns to the north from winter to the future, the sun moves back and forth into a new cycle, the height of the sun rises from now on, and the days get longer day by day, so the spring water in the mountain can flow and be warm at this time.

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.
