When does the solar term enter nine?

The meaning of the number nine

The number nine is counted from the winter solstice in the 24 solar terms, and every 9 days is counted as 19, and so on. Generally, March 9 is the coldest time in winter. After counting to 99 days (998 1 day), it is time for spring to warm the earth and everything to be full of vitality.

Law No.9 is passed down from mouth to mouth in our country, and there will be some records in history. As for when it originated, there is no exact information. However, it was popular at least in the Southern and Northern Dynasties. In the Chronicle of Jingchu, Liang wrote: The number of days from winter to day, 998 1 day is the end of the cold.

Winter solstice time in 2020: 65438+February 2 1, 18: 02: 12, lunar calendar in 20201/the seventh day of the month.

The winter solstice is the shortest day of the year in the northern hemisphere. From winter to the future, the direct point of the sun gradually moves northward, the northern hemisphere begins to get longer during the day, and the height of the sun gradually increases at noon. Therefore, there is a saying, "Eating noodles on the solstice in winter will make the day longer."

Calculation of the number nine

From the winter solstice to the winter non-healing day (the first non-healing day is called "Fu Jiu" from winter to the future, which means that the cold time is about to begin), every nine days is called "Jiu Jiu", the first nine days are called "Jiu Jiu", the last nine days are called "Er Jiu", and so on, until it reaches "Jiu Jiu" and "Jiu Tao Hua", the weather will change. It is usually the coldest on March 9, which is the coldest time of the year. By the ninth five-year plan, the cold will be gone and spring will warm the earth.

The correct algorithm of "counting nine" begins from winter to the first nonunion day in the future. Therefore, the specific date of "September" is not fixed every year, but depends on the first nonyl day after the winter solstice. Another mistake is that the number nine is counted from the date of winter solstice, so the specific time of nine is fixed every year from the date of winter solstice, and each nine is fixed on the ninth day, 18 and the 27th day after winter solstice. Obviously, it is wrong to count nine from the winter solstice. As the saying goes, "Summer solstice is three years old, and winter solstice is nine years old."
