Historical origin of solar terms in autumnal equinox

Twenty-four solar terms: "See the vernal equinox in mid-August". "Divide" means to divide day and night equally. Like the vernal equinox, the sun shines directly at the equator of the earth, and day and night are equal. After that, the days became shorter and the nights became longer. In the first half of the spring and autumn period, yin and yang came in and out. It is said that "the autumnal equinox, yin and yang are also half-phase, so it is cold and hot day and night." The autumnal equinox is just in the middle of 90 days in autumn, which means "equal share", so it is called "autumnal equinox".

The autumnal equinox used to be the traditional "Festival of Sacrificing the Moon". Now Mid-Autumn Festival comes from the traditional autumnal equinox "offering sacrifices to the moon". According to textual research, the Mid-Autumn Festival was originally set on the day of the autumnal equinox, but because this day is not always a full moon, the Mid-Autumn Festival was later transferred from the twenty-four solar terms of the autumnal equinox to the fifteenth day of the eighth lunar month.
