202 1 count nine times

"September 19" is 65438+February 2 1 to 29.

February 30, 65438 to 20221October 7.

"Sanjiu" is 65438+1October 8 to 16.

The period of "the Ninth Five-Year Plan" is165438+ from October 26th to February 3rd.

June 9th is from February 4th to February 12.

July 9th is February 13 to February 2nd1.

August 9th is from February 22nd to March 2nd.

September 9th is from March 3rd to 1 1.

In this way, 65438+February 2 1 is the first day of the ninth grade, and March 12 is the ninth grade. But it is said that the coldest season of the year is in the stages of "March 9" and "April 9". After all, "March 949 on the Ice" is enough to illustrate its cold degree.

Winter solstice in the middle of the month, throwing cotton-padded jacket at the end of the year:

In people's eyes, the winter solstice is different in different positions in the lunar month, which means "the winter solstice ends, the weather is cold in the year, and the cotton-padded jacket is thrown at the end of the year;" The solstice at the end of winter, the great cold is in February. "

The meaning of this proverb is obvious. If the winter solstice falls on the first day of the first lunar month, it means that the temperature is cold around the Spring Festival and needs to be protected.

If the solstice in winter is in the middle of the lunar calendar, winter will not be too cold. Just put on your new year's light clothes and put away your cotton-padded jacket. If the winter solstice falls at the end of the lunar calendar, it means that there is a high probability of "late spring cold" after beginning of spring, and the weather in February of the lunar calendar is extremely cold.
