When are early winter and late winter?

According to the inquiry and understanding of life, the time of early winter and late winter is as follows:

1, early winter refers to Meng Dong, and the first month of winter is usually October of the lunar calendar.

2. Deep winter refers to slight cold and severe cold. Great cold is the coldest time of the year. The Gregorian calendar 65438+1October 5th and 20th are mild and severe cold.

Winter is one of the four seasons. Traditionally, the 24 solar terms "beginning of winter" are the beginning of beginning of winter, and "beginning of winter" refers to wind and rain, humidity, light, temperature and so on. It is at a turning point, and it begins to transition from autumn to winter. In winter, that is, "everything will be harvested in the end", after beginning of winter, everything began to be hidden. Li Si's division of four seasons reflects many characteristics such as climate and phenology. At present, four seasons are often divided according to the temperature change, and the method of "weather average temperature" proposed by modern scholar Zhang Baokun is adopted. According to the four seasons divided by the weather average temperature method, the daily average temperature is equal to or lower than 10 degrees Celsius for five consecutive days, which is regarded as winter.
