When the difference changes

|---|---|---|
| 1 January – 29 March | 7 hours behind | — |
| 29 March – 25 October | 6 hours behind | United Kingdom Time clocks go forward one hour |
| 25 October – 1 January | 7 hours behind | United Kingdom Time clocks go back one hour |
Dates are Western Indonesia Time local dates for 2026. Transition dates move by a few days from year to year; the rule each country follows does not.
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 United Kingdom Time
The United Kingdom is on GMT (UTC+0) for about five months and BST (UTC+1) for the rest, changing on the last Sunday in March and the last Sunday in October. Ireland keeps exactly the same clock, so every figure here applies to Dublin as well as London.
Cities on this clock: London, Lisbon, Dublin, Edinburgh, Manchester.
How the difference is worked out
The gap between Western Indonesia Time and United Kingdom Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 6 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 — United Kingdom Time is 7 hours behind 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 Europe/London. Nothing is looked up on a server and nothing about your visit is recorded.
