Twenty-four solar terms formula

The jingle of the 24 solar terms table is:

Spring rain surprises spring and bright valley days, and summer is full of mans and summer heat is connected;

Autumn dew, autumn frost, little snow in winter and cold in winter.

There is no change in the two festivals every month, with a maximum difference of one or two days;

In the first half of the year, there were six bends and twenty-one, and in the boring year before the second half of the infiltration, there were eight bends and twenty-three.

This song is compiled according to the rules of the famous regret shirt, which is easy to remember. The first four sentences are composed of one word in each solar term in sequence, which is the main body of the whole solar term song, and the last four sentences are the time laws of the 24 solar terms. That is, in the first half of the year, the solar terms are around the 6th and 2 1 of each month, and in the second half, around the 8th and 23rd of each month.

social influence

Historically, the 24 solar terms have already gone abroad and gone to the world, affecting the Korean Peninsula, Japan and Southeast Asia. In some places, although the seasonal changes are not obvious, people there are still inheriting and carrying forward the 24 solar terms and their accompanying culture, which fully shows its cultural value. Twenty-four solar terms have been accepted by Korea, Japan and other countries as early as ancient times, and have been used in modern times in combination with their actual situation and national culture.

In the traditional calendar of Vietnam, most of the "24 solar terms" have been retained, and the time of some solar terms has been changed, which is more suitable for the actual situation in Vietnam. Although Vietnamese officials use the solar calendar, some people still use the traditional lunar calendar, especially farmers, who still arrange agricultural production according to the solar terms.
