Autumnal equinox (one of the twenty-four solar terms)

The autumnal equinox is the sixteenth of the twenty-four solar terms, and the fourth solar term in autumn. Fight refers to oneself; the sun reaches 180° of the yellow longitude; it meets every year on September 22-24 in the Gregorian calendar. On the autumnal equinox, the sun is almost directly at the earth’s equator, and day and night are equal in length all over the world. The autumnal equinox means “equal” and “half”. In addition to the equinox of day and night, it also means that autumn is divided equally.
