About Seoul Time

Seoul uses Korea Standard Time (KST), which is UTC+9 year-round. South Korea does not observe Daylight Saving Time, making KST a fixed, predictable offset. Seoul and Tokyo share the same UTC+9 offset, though they use different IANA timezone identifiers (Asia/Seoul vs. Asia/Tokyo). The practical result is that Seoul and Tokyo are always synchronised.

The Korea Exchange (KRX) trades from 9:00 AM to 3:30 PM KST on weekdays. Seoul is the home of Samsung, LG, Hyundai, and SK Group, making South Korea's capital a critical scheduling hub for the global semiconductor, electronics, and automotive supply chains. For US technology and consumer electronics companies, keeping track of Seoul time is essential for coordinating with Korean component suppliers and manufacturing partners.

South Korea's technology sector has made Seoul a significant node in the global chip supply chain alongside Tokyo and Taipei. The UTC+9 position means Seoul, like Tokyo, is nearly inverted from New York time — 14 hours ahead in winter — requiring most Korea-US coordination to happen via asynchronous communication or early Seoul mornings/late US evenings.
