When the difference changes
British Time and Western Indonesian Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – October 25, 2026Western Indonesian Time is 6 hours ahead
- October 25, 2026 – March 28, 2027Western Indonesian Time is 7 hours ahead
- March 28, 2027 – onwardsWestern Indonesian Time is 6 hours ahead
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
British Time
Clocks go back one hour at 2am local time, becoming GMT.
Western Indonesian Time
Western Indonesian Time stays on WIB all year, so its offset from UTC never moves.

Working hours overlap from 9:00 am to 12:00 pm BST, which is 3:00 pm to 6:00 pm WIB. Anything inside that window falls in the normal working day at both ends.
A note on BST: it can also mean Bangladesh Standard Time (UTC+6). This page means British Summer Time.
British Time (BST) is used in the whole United Kingdom. In winter the UK is on GMT; from late March to late October it is on BST, an hour ahead.
