SGT to UTC
Coordinated Universal Time is 8 hours behind Singapore Time, all year round.
SGT to UTC conversion table
Every hour of the day, Singapore Time to Coordinated Universal 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 Singapore Time ends no time at all before the Coordinated Universal Time one begins, so any live call sits outside somebody's working hours.
The shortest reach is the edges: early morning in SGT against late evening in UTC, or the other way round.
When the difference changes
It doesn't. Coordinated Universal Time is 8 hours behind Singapore Time on every date of the year. Singapore Time runs at UTC+08:00; Coordinated Universal Time runs at UTC+00:00.
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.
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.
How the difference is worked out
Neither Singapore Time nor Coordinated Universal Time moves its clock relative to the other, so coordinated universal time is 8 hours behind singapore 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 — Coordinated Universal Time is 8 hours behind Singapore 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 Asia/Singapore and UTC. Nothing is looked up on a server and nothing about your visit is recorded.
Is UTC ahead of or behind SGT?
Coordinated Universal Time is 8 hours behind Singapore Time, all year round. Singapore Time runs at UTC+08:00; Coordinated Universal Time runs at UTC+00:00. Because neither zone changes its clock, the gap never moves.
What time is 9 AM SGT in UTC?
9:00 AM SGT is 1:00 AM UTC.
When can Singapore Time and Coordinated Universal Time meet?
They do not overlap. A 09:00–17:00 working day in Singapore Time ends no time at all before the Coordinated Universal Time one begins, so a call has to sit outside someone's working hours — early morning in Singapore Time or late evening in Coordinated Universal Time is usually the shortest reach.
What does SGT stand for?
SGT is Singapore Time, also written SST, 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.
