2. The autumnal equinox is the sixteenth of the twenty-four solar terms, and the time is generally from September 22nd to September 24th in the Gregorian calendar every year. On the day of the autumnal equinox, the sun reaches the longitude 180 (autumnal equinox), almost reaching the equator of the earth, and the length of day and night is equal all over the world (regardless of the refraction of the sun light by the atmosphere and the shadow in the morning). In ancient times, there was a folk activity of "offering sacrifices to the sun in spring and the moon in autumn". The autumnal equinox used to be the traditional "Moon Festival" (Mid-Autumn Festival), which evolved from offering sacrifices to the moon in autumn.
