Time in Busan, South Korea

Busan, South Korea runs on UTC+9 — written as KST (Korea Standard Time). That offset is what the live clock at the top of this page uses, so the time you see always matches the real local clock in Busan.

No — Busan stays on the same offset all year with no daylight-saving changes, so the gap to other places only moves when the other side changes its clocks.

The fastest way is a converter: pick your own zone and you’ll get the matching Busan time instantly, for any date. You can also open the full KST conversion list to compare Busan against every other zone.

The big clock at the top updates every second, so you can leave this page open and glance at it. Running an event or watching a launch from afar? Tap the fullscreen icon to throw the Busan clock onto a big screen.

It’s calculated from the IANA time zone database — the same source your phone and computer rely on — not a fixed number that drifts when the rules change. So the Busan time here stays correct through daylight-saving switches and into the future.
