What is the time difference between Tokyo and Singapore?

Tokyo (JST, UTC+9) is always 1 hour ahead of Singapore (SGT, UTC+8). Neither country observes Daylight Saving Time, so this gap never changes throughout the year.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished DST in 1952 and has not used it since. Tokyo stays on JST (UTC+9) all year.

Does Singapore observe Daylight Saving Time?

No. Singapore operates on SGT (UTC+8) year-round and has not observed DST since 1941. The 1-hour gap between Tokyo and Singapore is fixed and permanent.

What are the best meeting times when calling from Tokyo to Singapore?

Because the offset is only 1 hour, the standard business hours (09:00–18:00) overlap almost entirely. Tokyo 09:00–18:00 corresponds to Singapore 08:00–17:00. Any hour between 09:00 and 17:00 JST is a solid meeting window.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

SGT stands for Singapore Standard Time. It is UTC+8, used across Singapore year-round. There is no Daylight Saving equivalent because Singapore does not observe DST.
