Autumn equinox will be celebrated at 4:02 p.m. Beijing time on Sept. 23, marking another equalization of day and night after the vernal equinox, the 16th of the 24 solar terms in the lunar calendar.

The autumnal equinox is the 16th of the 24 solar terms in the lunar calendar, and occurs around September 23 on the Gregorian calendar every year. It falls in the middle of the 90 days of autumn, and is called the "Autumn Equinox" because it means "the equal parting of the colors of autumn". On this day, the sun shines directly on the Earth's equator, distributing its light and warmth evenly between the northern and southern hemispheres. In the ancient book "Spring and Autumn Annals", it is said: "Autumn equinox is the half of yin and yang, so the day and night are even and the cold and heat are even."

From the autumn equinox onward, the direct sunlight increasingly favors the southern hemisphere, and the days are shorter than the nights, day after day, until the winter solstice.
