What is the exact order of the 24 solar terms in the lunar calendar?

1, the order is beginning of spring, rainy, smelly, vernal equinox, Qingming, Grain Rain, Changxia, Xiaoman, Mang, Summer Solstice, Xiaoshu, Dashu, beginning of autumn, Chushu, Bailu, Autumn Equinox, Cold Dew, Early Frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice, Slight Cold. ?

2. The current "twenty-four solar terms" come from the "Atmospheric Law" concluded more than 300 years ago. It is a knowledge system formed by observing the movement of the sun in a year and understanding the changing laws of the four seasons, climate and phenology in a year. It divides the orbit of the sun in one year into 24 equal parts, corresponding to a certain position reached by the sun every time it runs 15 on the ecliptic, and each equal part is a "solar term".

3. Twenty-four solar terms represent the twenty-four different positions of the earth in the orbit of revolution. Moreover, each solar term represents different changes in climate, phenology and time. The spring rain shakes the spring and clears the valley, and the summer is full of mountains and summers. Autumn dew, autumn frost, little snow in winter and cold in winter. The solar term song, which is well known to China people, implies the order of the 24 solar terms.

The earth's orbit around the sun was named "ecliptic" by the ancients, also known as "sun path". The ecliptic is divided into 24 equal parts, separated by 15, forming 24 solar terms. The 24 solar terms are actually 24 solar terms, 2 per month. It is divided according to the laws of heaven and earth to determine the starting point and ending point of the four-season cycle.

The starting date of the 24 solar terms is almost the same as the international Gregorian calendar, with a difference of one or two days at most, which is precisely because the solar terms, like the Gregorian calendar, are all based on the earth's rotation around the sun once a year. Twenty-four solar terms are related to the periodic motion of the earth around the sun, and their days and months are determined by the apparent motion of the sun, and have nothing to do with the moon phase.

But it is different from the usual solar calendar (such as Gregorian calendar). The length of the solar calendar is artificially specified and has nothing to do with the astronomical phenomena, so it is a solar calendar with China characteristics.
