Current Time in Seoul, South Korea

Seoul follows the KST time zone, which is GMT+9 relative to Coordinated Universal Time (UTC). Seoul does not observe Daylight Saving Time (DST). The clock stays at KST (GMT+9) year-round, making it simpler to coordinate across time zones. The IANA timezone identifier for Seoul is `Asia/Seoul`, which is the internationally standardized reference used by operating systems, programming languages, and scheduling software worldwide.
