During the period of Emperor Wu of the Western Han Dynasty, the "Twenty-four solar terms" were absorbed into the taichu calendar method, and the solar terms were measured in the Yellow River basin by the method of soil return surveying and mapping, as a supplement to the calendar, to guide the farming in the northern part of the Central Plains. In the Yellow River Basin, the day with the longest sun shadow and the shortest day (the shortest day) is the winter solstice, and the winter solstice is the starting point of the "24 solar terms". The winter solstice and the next winter solstice are divided into 24 equal parts, the time between each solar term is equal, and the interval between each solar term is 15 days.

The current "twenty-four solar terms" come from the "fixed gas method" concluded more than 300 years ago (it has been used since 1645). The current "twenty-four solar terms" are formulated according to the position of the sun on the ecliptic, that is, the annual movement track of the sun is divided into 24 equal parts, and each 1 equal part is 1 equal part. There are 24 solar terms, each of which represents different changes in climate, phenology and time. In the historical development, the 24 solar terms have been incorporated into the lunar calendar and become an important part of the lunar calendar.
