How to calculate the month of each season in spring, summer, autumn and winter?

Generally speaking, according to the solar terms, beginning of spring (February 4th or 5th) is spring, long summer (May 5th or 6th) is summer, beginning of autumn (August 7th or 8th) is autumn, and beginning of winter (165438+1October 8th or 9th) is winter.

Here are two other common scientific methods to divide seasons:

Lunar calendar division method: China folks traditionally use the lunar calendar to divide the four seasons. Lunar calendar1~ March is spring, April-June is summer, July-September is autumn, and 10 ~ 12 is winter. The first day of the first month is the first day of the year and the first day of spring, so it is also called the Spring Festival. ?

Division of waiting temperature: This division is based on waiting time (five days is a waiting time). Take the average temperature as the temperature index to divide the four seasons. Summer begins when the average climate temperature is stable above 22℃, winter begins when the average climate temperature is stable below 10℃, and spring and autumn begins when the average climate temperature is between 10 ~ 22℃. 10℃ to 22℃ is spring, and 22℃ to 10℃ is autumn.
