What exactly is the autumnal equinox?

Day and night are equinoxized. The time of day and night is equal, and the days and nights are gradually shortened and the nights are shortened. Because the Sun reaches 180 degrees of ecliptic longitude on this day and will shine directly at the Earth's equator, the 24-hour day is as long as night and day in most parts of the world, which is 12 hours of day and night.

After the autumnal equinox, as the direct point of the sun gradually enters the southern hemisphere from the equator, the days and nights begin to appear in the northern hemisphere, and the time of the day begins to be shorter than the night in a day. In the Southern Hemisphere, the opposite is true, with longer daylight hours than nights.
