How to distinguish between spring, summer, autumn and winter?

There are different standards for division. The following are some common divisions:

1. Astronomy: Four neutral gases, namely "dichotomy": vernal equinox, summer solstice, autumn equinox and winter solstice, are regarded as the beginning of four seasons. It is a solar term divided according to the China lunar calendar.

2. Ancient China: The "four solar terms" of beginning of spring, Changxia, beginning of autumn and beginning of winter, as the beginning of the four seasons, were also divided according to the solar terms of the lunar calendar.

3. In the Gregorian calendar (Gregorian calendar), 65438+ 10 is the most Leng Yue and July is the hottest month, so March, April and May are spring, June, July and August are summer, and September 10/1is autumn. This division of four seasons is more suitable for temperate regions with distinct seasons, and this division is not applicable.

Fourth, in the lunar calendar, the first month, February and March of the lunar calendar are spring, April, May and June are summer, July, August and September are autumn, and October, November and December are winter. This division method also has the problem of poor applicability.

One point, two points and four points are all divided according to the lunar calendar (including solar terms and lunar months).

If it works, adopt it.
