On what day do you start counting?

The number nine starts from the winter solstice in the second half of June (65438+February) of the solar calendar every year, which is a more suitable solar term in northern China, especially in the middle and lower reaches of the Yellow River.

From the day of winter solstice, you will enter the "number nine", commonly known as "cross nine", and then every nine days will be a unit, which will be called "nine". After nine "nines", it happens to be 8 1 day, that is, "nine out", and then spring blossoms.

Count nine weather changes.

The coldest period in winter usually occurs after the winter solstice. After beginning of winter, it means that it has entered winter, but it doesn't mean that it has started to be cold. Therefore, the heat stored on the surface in the second half of the year still has some energy, so it will not be very cold.

There is a folk saying "It's sunny in October". "Xiaoyangchun in October" refers to the sunny, warm and comfortable "Xiaoyangchun" weather during the winter. So early winter (Meng Dong) is generally not very cold, but with the passage of time, cold air frequently goes south and the temperature gradually drops.
