What month is September?

China has been in cold weather for several years since the winter of November. Astronomical experts said that "the Ninth Five-Year Plan" is a more applicable solar term in northern China, especially in the middle and lower reaches of the Yellow River. From the day of winter solstice, it entered the "number nine", commonly known as "cross nine", and then every nine days as a unit, called "nine". After nine "nines", it is exactly eighty-one days, that is, "nine out", and then spring blossoms. Therefore, according to the winter solstice on February 22, 65438 this year, 65438+ 10 will enter Sanjiu next year, and the last day of Sanjiu will be 65438+10/8.
