Winter solstice (English: winter? Solstice), also known as "Winter Festival" and "Happy Winter", is one of the twenty-four solar terms in China and one of the eight astronomical solar terms, which is opposite to summer solstice. The winter solstice begins when the sun reaches 270 degrees of the yellow meridian, which is about 65438+February 22 of the Gregorian calendar every year. According to legend, the solstice in winter is the New Year's Day of the Zhou Dynasty in history, and it was once a very lively day.

On the winter solstice, the direct position of the sun on the ground reaches the southernmost point of the year and almost directly reaches the Tropic of Capricorn (23 26' south latitude). On this day, the northern hemisphere gets the least sunshine, 50% less than the southern hemisphere. The days in the northern hemisphere are the shortest, and the farther north they are, the shorter they are.

The specific date of the dog days is determined by the solar term date and the dry branch date. According to the traditional calculation method in China, the third and fourth Geng days from summer to the future are the start dates of the first (recumbent) and the second (recumbent) respectively, and the first Geng day after beginning of autumn is the first day of the last (recumbent). Gengri is a day with the word "Geng" in the year of Ganzhi, such as Gengzi, Gengyin and Chen Geng. Such a date will be published every year in the book "Rural Years".
