Hangawi/Chuseok was the day on which Koreans, an agrarian people throughout most of history, gave thanks to their ancestors for the year’s harvest, and shared their abundance with family and friends.
Although the exact origin of Chuseok is unclear, the tradition may be found at ancient religious practices that centered around the moon. The sun’s presence was considered routine, but the full moon that came once a month was considered a special and meaningful event. Therefore, harvest festivities took place on the day of the bright, full moon or August 15 on the lunar calendar system.
