Of the 24 solar terms, what solar term is today?

Among the 24 solar terms, today's solar term is the autumnal equinox.

The autumnal equinox is one of the 24 solar terms of traditional festivals in China. On September 22nd, 23rd or 24th of Gregorian calendar, the sun reaches 180 degrees. The meaning of the "twenty-four solar terms" in the autumnal equinox: "See the vernal equinox in mid-August". "Divide" means to divide day and night equally. Like the vernal equinox, the sun shines directly on the equator of the earth on this day, and day and night are equal.

From then on, direct sunlight began to enter the southern hemisphere, and the northern hemisphere began to have shorter days and longer nights, and the temperature dropped, which was of universal significance throughout the country. At the autumnal equinox, "fen" means "half". At the autumnal equinox, most parts of the earth are equally divided day and night, each with 12 hours; Near the North Pole and South Pole, the sun can be observed on the horizon all day on this day.

After the autumnal equinox, the days in the northern hemisphere are short and the nights in the southern hemisphere are long. The characteristics of the autumnal equinox are very special among the 24 solar terms.
