CET to WIB

About Central European Time

Central European Time covers most of the continent, from Spain to Poland, at UTC+1 as CET and UTC+2 as CEST. Every EU country changes at the same instant — 01:00 UTC on the last Sunday of March and of October — rather than at 02:00 local like North America, so the whole bloc moves together and the steps between European zones never wobble.

Cities on this clock: Paris, Berlin, Madrid, Rome, Amsterdam, Brussels, Vienna, Warsaw.

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.

How the difference is worked out

The gap between Central European Time and Western Indonesia Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 5 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 — Western Indonesia Time is 6 hours ahead of Central European 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 Europe/Paris and Asia/Jakarta. Nothing is looked up on a server and nothing about your visit is recorded.
