The traditional Chinese lunar calendar divides the year into 24 solar terms. Autumn Equinox, (Chinese: 秋分), the 16th solar term of the year, begins this year on Sept 23 and ends on Oct 7.

Autumn Equinox lies at the midpoint of autumn, dividing autumn into two equal parts. After that day, the location of direct sunlight moves to the south, making days shorter and nights longer in the northern hemisphere.
