South Korea normally observes Chuseok as a three-day public holiday.
The holiday period includes Chuseok Day itself, the day before it, and the day after it. Because Chuseok follows the lunisolar calendar, its dates shift each year on the Gregorian calendar, but the standard statutory holiday length remains three days.
This extended break supports one of the festival’s most visible traditions: families traveling to ancestral hometowns and gathering for meals, memorial rites, and visits to family graves. The holiday is therefore associated with exceptionally heavy road, rail, and air traffic across South Korea.
The three-day period can become longer when the government designates temporary holidays or when substitute holidays apply. For example, additional days have occasionally been added around Chuseok to encourage domestic travel or ease scheduling. Those exceptional arrangements should not be confused with the normal three-day public holiday.
