"The autumnal equinox" has two meanings:

First, the sun reaches 180 degrees of ecliptic longitude on this day and hits the earth's equator, so the day is 24 hours a day, and the day and night are equally divided, each 12 hours; The global phenomenon of infinite diurnal and nocturnal. After the autumnal equinox, the polar night range near the North Pole becomes larger, and the polar day range near the South Pole increases.

Second, according to the ancient Chinese division method of starting with the beginning of spring, summer, autumn and winter, the autumn equinox is among the 90 days of autumn, and the autumn is equally divided.

In ancient China, the autumn equinox was divided into three phases: "one is the beginning of the thunder; secondly, stinging insect blank households; Three wait for the water to start drying". The ancients believed that thunder was made because of the strong yang energy, and after the autumn equinox, the yin energy began to flourish, so it no longer thundered.

On the day of the autumnal equinox, the direct point of sunlight reaches 180° of yellow longitude (autumnal equinox), almost directly hitting the Earth's equator, and the day and night are equal in length around the world (not considering the refraction of sunlight by the atmosphere and the shadow of morning and dusk).

After the autumnal equinox, the direct point of the sun continues to move from the equator to the southern hemisphere, and the days and nights begin to be shorter and longer in the northern hemisphere, that is, the days begin to be shorter than the nights in a day. The Southern Hemisphere is the opposite. Therefore, the autumn equinox is also called the descending equinox. And at the North and South Poles, on the day of the autumnal equinox, the sun is on the horizon all day.
