UTC to SGT
Singapore Time is 8 hours ahead of Coordinated Universal Time, all year round.
UTC to SGT conversion table
Every hour of the day, Coordinated Universal Time to Singapore Time. The gap never changes, so this table holds on every date.

Shared working hours
They do not overlap at all. A 09:00–17:00 working day in Coordinated Universal Time ends no time at all before the Singapore Time one begins, so any live call sits outside somebody's working hours.
The shortest reach is the edges: early morning in UTC against late evening in SGT, or the other way round.
When the difference changes
It doesn't. Singapore Time is 8 hours ahead of Coordinated Universal Time on every date of the year. Coordinated Universal Time runs at UTC+00:00; Singapore Time runs at UTC+08:00.
About Coordinated Universal Time
UTC never shifts. It is the reference every other zone is defined against, which is why logs, flight schedules and protocol timestamps use it. GMT is the same clock for every civil purpose, so a query for one is answered by the other.
Cities on this clock: Reykjavik, Accra, Abidjan, Dakar.
Watch out: GMT is also used loosely to mean "UK time", and those are not the same thing for seven months of the year — the United Kingdom moves to BST (UTC+1) while UTC stays put.
About Singapore Time
Singapore is a fixed UTC+8 even though it sits near 104°E, where solar noon falls closer to UTC+7 — it moved forward half an hour in 1982 to share a clock with peninsular Malaysia and Hong Kong. The practical effect is that the sun there rises and sets unusually late for the clock.
Cities on this clock: Beijing, Shanghai, Guangzhou, Shenzhen, Chongqing, Taipei, Hong Kong, Singapore.
How the difference is worked out
Neither Coordinated Universal Time nor Singapore Time moves its clock relative to the other, so singapore time is 8 hours ahead of coordinated universal time is a rule rather than a fact about one particular year. The hour-by-hour table above holds on every date.
With both zones on their own standard time — daylight saving not in force anywhere — Singapore Time is 8 hours ahead of Coordinated Universal Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.
Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids UTC and Asia/Singapore. Nothing is looked up on a server and nothing about your visit is recorded.
Is SGT ahead of or behind UTC?
Singapore Time is 8 hours ahead of Coordinated Universal Time, all year round. Coordinated Universal Time runs at UTC+00:00; Singapore Time runs at UTC+08:00. Because neither zone changes its clock, the gap never moves.
What time is 9 AM UTC in SGT?
9:00 AM UTC is 5:00 PM SGT.
When can Coordinated Universal Time and Singapore Time meet?
They do not overlap. A 09:00–17:00 working day in Coordinated Universal Time ends no time at all before the Singapore Time one begins, so a call has to sit outside someone's working hours — early morning in Coordinated Universal Time or late evening in Singapore Time is usually the shortest reach.
What does UTC stand for?
UTC is Coordinated Universal Time, also written GMT, Greenwich Mean Time, Zulu time. GMT is also used loosely to mean "UK time", and those are not the same thing for seven months of the year — the United Kingdom moves to BST (UTC+1) while UTC stays put.
