On which lunar date is Chuseok, Korea’s harvest festival, celebrated?

Chuseok is celebrated on the 15th day of the eighth lunar month.

Because it follows the lunisolar calendar, Chuseok moves across September and October on the Gregorian calendar. Its date coincides with the full moon, a feature shared with several East Asian harvest traditions.

The holiday period normally includes the day before and the day after the main festival day. This means the official break is commonly three days, although weekends and additional public holidays can make travel periods longer.

Chuseok is associated with the autumn harvest, family gatherings, ancestral rites, grave visits, songpyeon rice cakes, and traditional games. It is sometimes compared with Thanksgiving, but the lunar date and rituals give it a distinct Korean history and cultural meaning.
