About Seoul time

Seoul keeps one clock.

In Seoul, the rhythm moves fast — tech companies and startups finish their workday in sync with Northeast Asia’s morning, making early stand-ups a norm for teams across the Pacific. South Korea’s consistent, no-daylight-saving schedule gives global teams a dependable anchor in a stable time zone that aligns closely with Japan and shares business hours with parts of China and Australia.

Frequently asked questions

Common questions about Seoul's time zone, daylight saving rules, and scheduling across it. Can't find what you need? Email [email protected].

Does Seoul observe daylight saving time?
No. South Korea has not used daylight saving time since 1988, so KST stays fixed year-round at GMT+9, making scheduling with Seoul consistently predictable despite seasonal shifts elsewhere.
Which time zone is Seoul in?
Seoul follows Korea Standard Time (KST), which is set at GMT+9 with no seasonal adjustments, aligning South Korea’s clocks with Japan and differing from neighboring China by exactly one hour.
What are typical working hours in Seoul?
Standard business hours usually run from 9 a.m. to 6 p.m., though in practice many professionals and tech teams frequently stay late — sometimes well past midnight — especially during project sprints and peak product cycles.
How does Seoul’s timezone benefit global teams?
Seoul’s GMT+9 offset allows overlap with both European afternoons and American mornings, while its lack of daylight saving changes means teams never have to adjust schedules twice a year like they do with US or EU partners.
When does the workday start in Seoul?
Businesses generally open around 9 a.m. to 10 a.m., but public transit is packed much earlier as many residents commute around 7:30 a.m. to 8:30 a.m. and evening activities often extend past midnight.
How does Taiwan’s timezone interact with Seoul?
Seoul is one hour ahead of Taiwan (GMT+8 vs. GMT+9), so when it’s 10 a.m. in Taipei, it’s already 11 a.m. in Seoul. This offsets peak productivity windows, which can help stagger handoffs across East Asian teams.
Is there any chance South Korea reintroduces daylight saving?
Occasional legislation has occasionally surfaced to reintroduce daylight saving for energy or business alignment reasons, but nothing has passed yet — for now, Seoul’s clocks stay consistent throughout the year.
