Current time in KST (Asia/Seoul)

What is Asia/Seoul?

Asia/Seoul represents Korea Standard Time at UTC+9. Korea's civil-time history includes changes during Japanese rule, post-liberation adjustments, and later stabilization without routine daylight saving. The IANA zone remains separate from Tokyo because legal history and past offsets differ even when today's standard offset matches. Seoul is the administrative and economic anchor, so its identifier is the right choice for Korean timestamps, market calendars, and national holidays. This protects Korean historical records from being flattened into a generic UTC+9 timestamp shared with Japan.

Seoul business hours commonly run from about 9:00 a.m. to 6:00 p.m., with a noon lunch break and heavy commuter peaks. Large conglomerates, banks, esports, entertainment firms, and public agencies value punctual schedules, but export-facing teams may take evening calls for US clients. Korea has also reduced statutory working-hour limits in recent years, so old assumptions about unlimited late work should be checked against current company practice. Holiday periods such as Seollal and Chuseok can remove several business days even when surrounding APAC teams remain active.

Use Asia/Seoul for Korean electronics, automotive, shipbuilding, gaming, K-pop and streaming releases, financial markets, government services, and national ecommerce. It is essential when Seoul-specific public holidays, market closures, or release embargoes differ from Japan despite the same UTC+9 offset. Use it when Korean market, entertainment, or manufacturing calendars matter more than simply matching the UTC+9 offset.
