South Korea’s Chuseok holiday period lasted ten days in 2017 after temporary holidays were added.
The unusually long break combined the regular Chuseok holiday period with other public holidays and a specially designated temporary holiday. This created an extended national travel and family-gathering period in early October.
South Korean holiday calendars normally provide several consecutive days around Chuseok, but the exact length can expand when weekends or additional public holidays connect with it. The 2017 arrangement was therefore exceptional rather than the standard duration.
The long break also affected transportation demand. Roads, railways, airports, and domestic travel routes experienced particularly heavy holiday traffic as people returned to ancestral hometowns or traveled with family.
