What season does the sunny day of 99 refer to?

"September 9" refers to September 19, February 29, March 9, April 9, May 9, June 9, July 9 and August 9, from winter to September 9, when the solar terms have awakened, spring is blooming, everything is reviving and the weather is unpredictable.

Three or nine days refers to the third cold day since the winter solstice, which is the coldest period in a year. The specific calculation method is: from winter to Sunday, every "nine days" is counted as a "nine", the first nine days are called "one nine", the second nine days are called "two nine", and so on, and the coldest period in a year is "three nine days, four nine days". Count to "999" 81 days, "nine peach blossoms bloom". At this time, the cold has passed and the weather is warm. There is a folk saying, "The solstice in summer is three years old, and the solstice in winter is nine years old." Law No.9 has been passed down from mouth to mouth in China since ancient times, with a history and a lack of records. As for when it originated, there is no exact information.

The correct algorithm of "counting nine" begins from winter to the first nonunion day in the future. Therefore, the specific date of "September" every year is not fixed, depending 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 counted from the date of winter solstice every year, and each "nine" is fixed on the ninth day, 18 and the 27th day after winter solstice? .
