The history of the twenty-four solar terms

The current "twenty-four solar terms" come from the method of dividing according to the degrees of the sun's yellow meridian, which was established more than 300 years ago and has been in use since 1645. However, from the tenth edition of the Chronicle of the Constitution to today's "Lunar Calendar" and "Fourteen solar terms" are determined according to the position of the sun on the return to the ecliptic (the degree of the solar ecliptic).

That is, on a 360-degree circle "ecliptic" (the apparent path of the sun on the celestial sphere in a year), it is divided into 24 equal parts, each equal part is15, with vernal equinox as the starting point of 0 degree (beginning of spring is still ranked first in the ranking), and arranged according to the degree of the longitude.

Depending on the fact that the sun starts from vernal equinox, that is, the longitude of the Yellow River is zero, at this moment, the sun shines vertically on the equator. Every time it advances, 15 degrees is a solar term, and it returns to vernal equinox once a week, which is a tropical year, and the 24 solar terms are exactly 360 degrees. Every time the sun moves 15 degrees on the ecliptic, it is a "solar term", and the degrees between each "solar term" are equal and the time is unequal.
