Time in Busan, South Korea

Time zone: KST (UTC/GMT +09:00) — Asia/Seoul

Busan keeps KST (9 hours ahead of UTC, UTC+09:00). Its database zone is Asia/Seoul — worth knowing if you are scheduling anything that has to survive a daylight saving change.

There is no daylight saving in Busan. UTC+09:00 applies all year, so the offset never moves on this side — only the other party's clock changes.

How Busan lines up against other major centres at this moment — the numbers move when either side changes its clocks.

Usable call slots from Busan, taking business hours as 09:00 to 17:00 in both places.

No shared working window exists with New York, Los Angeles, London or Sao Paulo, so those calls have to sit outside somebody's normal hours.

These South Korea cities also use Asia/Seoul, so their clocks read identically to Busan at every moment of the year.
