Time in Hyesan, North Korea

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

Hyesan runs on KST. That places it 9 hours ahead of UTC (UTC+09:00); in a calendar, server config or booking form, select Asia/Pyongyang.

Hyesan does not change its clocks. The same UTC+09:00 offset holds in January and July, which makes it a stable anchor for recurring calls.

Hyesan has roughly 192,680 residents and ranks 12th by population among the North Korea cities on this site.

Current gap between Hyesan and cities people most often need to coordinate with. These figures already account for daylight saving where it applies.

Where the two working days actually meet, expressed in Hyesan local time.

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.

Same zone, same time — each of these sits on Asia/Pyongyang alongside Hyesan, including through any clock change.
