When did the "Nineteen and Twenty-Nine" in the Nineteen Songs begin to count?

Count to nine from winter to the future. The winter solstice is June 65438+February 2 1 ~ 23 in Gregorian calendar every year.

The coldest period every year is called "several nine days", which is a verb. Just like counting days, we start counting days from the winter solstice, the first nine days are "19", the second nine days are "29", and so on until the ninth nine days. That is, "a few days" * * has 81 days.

When the custom of "counting nine" originated, there is no exact information at present. However, it was popular at least in the Northern and Southern Dynasties. Liang wrote in the Chronicle of Jingchu: "The number of days in the winter solstice, 9981 is the end of the cold."

From counting to nine (commonly known as "winter solstice"), it really entered the coldest winter of the year. That is, from the winter solstice to the Sunday, a "nine" is counted every nine days until the "nine-nine" of 81 days, which roughly includes the three-month winter in the Gregorian calendar. Among them, Sanjiu and Jiu Si are the coldest.
