Chuseok is a major harvest festival and a three-day holiday in Korea celebrated on the 15th day of the 8th month of the lunar calendar. Like many other harvest festivals, it is held around the Autumn Equinox. As a celebration of the good harvest, Koreans visit their ancestral hometowns and share a feast of Korean traditional food.
In modern South Korea, on Chuseok there is a mass exodus of Koreans returning to their hometowns to pay respects to the spirits of one's ancestors. People perform ancestral worship rituals early in the morning. They often visit the tombs of their immediate ancestors to trim plants and clean the area around the tomb, and offer food, drink, and crops to their ancestors. Harvest crops are attributed to the blessing of ancestors.
