About Western Indonesia Time
Indonesia spans three zones; WIB is the western one, at a fixed UTC+7, and it covers Jakarta, Sumatra and most of the population. Central Indonesia is an hour ahead and the east two, so "Indonesia time" is only unambiguous once you know which.
Cities on this clock: Jakarta, Bangkok, Ho Chi Minh City, Hanoi, Phnom Penh.
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 Western Indonesia Time nor Singapore Time moves its clock relative to the other, so singapore time is 1 hour ahead of western indonesia 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 1 hour ahead of Western Indonesia 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/Jakarta and Asia/Singapore. Nothing is looked up on a server and nothing about your visit is recorded.
