When does the counting of nine start?

Jiujiu, also called Jiujiu in winter, is a folk method in China to calculate the flowering date in cold weather and warm spring. The so-called "number nine" means that from the date of the "winter solstice", nine days is a unit, and nine "nines" have passed, which is exactly 8 1 day, that is, "nine out". From "September 19th" to "September 9th", the cold winter turned into a warm spring.

Information piece: Solstice of winter (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. In northern China, there is a custom of eating jiaozi on the solstice in winter. As the saying goes, "When winter solstice comes, eat jiaozi." In the south, we eat jiaozi, but there are exceptions. For example, in Tengzhou, Shandong Province, the solstice in winter is called Jiujiu, and the custom of drinking mutton soup on that day is very popular, which means driving away the cold.

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.
