About Seoul time
Seoul runs on Korea Standard Time, nine hours ahead of UTC, coordinating one of Asia’s most connected digital economies.
South Korea briefly reintroduced DST around the 1988 Olympics but has otherwise kept a steady UTC+9 for decades. Seoul’s hyper-connected culture means services and markets run late into the night, and the lunar New Year (Seollal) and Chuseok harvest festival cause the country’s biggest travel and business pauses.
