SGT to AEST

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.

About Australian Eastern Time

Sydney, Melbourne and Canberra run at UTC+10 as AEST and UTC+11 as AEDT, changing on the first Sunday in October and the first Sunday in April. Queensland does not change at all, so Brisbane matches Sydney for about half the year and sits an hour behind it for the rest — on the same "Eastern" label.

How the difference is worked out

The gap between Singapore Time and Australian Eastern Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 3 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — Australian Eastern Time is 2 hours ahead of 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 Australia/Sydney. Nothing is looked up on a server and nothing about your visit is recorded.
