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, with the weather gradually cooling down. During this time, crops ripen and are ready for harvest, and people celebrate the abundance of the season. Autumn Equinox, the 16th solar term of the year, begins this year on Sept 23 and ends on Oct 8.
秋分日居于秋季的中點,將秋天平分。此后,太陽直射點持續南移,北半球白晝漸短、黑夜漸長,天氣也逐步轉涼。這個時節,農作物成熟待收,人們慶祝季節饋贈的豐饒。作為二十四節氣里的第16個節氣,今年秋分自9月23日起始,至10月8日結束。
