It is not only a time system that guides agricultural production, but also a folk system that contains rich folk customs. The twenty-four solar terms contain a long cultural connotation and historical accumulation, and are an important part of the long history and culture of the Chinese nation.

After historical development, the lunar calendar absorbed the solar terms of the Ganzhi calendar as a supplement to the calendar, and adjusted it to conform to the tropic year by "setting leap", forming a combined calendar of yin and yang. The "twenty-four solar terms" became an important part of the lunar calendar, which had a great influence on the almanac making of later generations and was one of the core theories of China's traditional meteorology.

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 national conditions 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, and still arrange agricultural production according to solar terms.
