Early autumn and late autumn:

Early autumn and late autumn are calculated according to the variation offset of the solar meridian before and after beginning of autumn. The solar ecliptic refers to the east longitude position of the sun on the ecliptic, based on the vernal equinox. Every year, beginning of autumn marks that the longitude of the sun is 135 degrees. At this time, the sun moves from south to north. Therefore, after beginning of autumn, the angle of sunlight becomes smaller, and the temperature gradually drops. In the calendar, taking beginning of autumn as a solar term can explain the change of the sun's running position more accurately and provide reference for agricultural production.
