How the gap moves through the year

The gap never changes: Seoul is 1 hour ahead of Singapore on every day of the year, because neither city uses daylight saving time.

Singapore does not change its clocks: it stays on UTC+8 (Singapore Standard Time) all year.

Seoul does not change its clocks: it stays on UTC+9 (Korean Standard Time) all year.

Everything on this page also holds if you swap Singapore for Shanghai, Beijing, Guangzhou, Shenzhen or Taipei, or Seoul for Tokyo, Busan, Pyongyang, Osaka or Dili — those cities follow exactly the same clock all year.

Working hours that overlap

In January, a 9-to-5 day in both cities shares 7 hours: 9:00 am–4:00 pm in Singapore, which is 10:00 am–5:00 pm in Seoul.

July gives exactly the same window.

Across the week

At 9:00 on a Monday morning in Singapore, it is 10:00 am on Monday in Seoul.
