What is the time difference between London and Jakarta?

Jakarta (WIB, UTC+7) is 7 hours ahead of London in winter (GMT, UTC+0) and 6 hours ahead in summer (BST, UTC+1). Jakarta does not observe Daylight Saving Time, so the offset changes only when the UK shifts its clocks in spring and autumn.

Does Jakarta observe Daylight Saving Time?

No. Jakarta uses WIB (Western Indonesia Time, UTC+7) year-round and does not observe DST. Only London shifts its clocks, which is why the London-Jakarta gap alternates between 7 and 6 hours each year.

When does the offset change from 7 to 6 hours?

The UK moves clocks forward on the last Sunday in March at 01:00 GMT, entering BST (UTC+1). At that point Jakarta goes from 7 hours ahead to 6 hours ahead. The gap returns to 7 hours on the last Sunday in October at 02:00 BST when the UK reverts to GMT.

What are the best meeting times for London and Jakarta?

During GMT (winter), a 09:00 London call lands at 16:00 in Jakarta — a good window before their close of business. During BST (summer), 09:00 London is 15:00 Jakarta, giving a comfortable overlap. An 09:00–12:00 London slot works well for both cities.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

WIB stands for Waktu Indonesia Barat, or Western Indonesia Time. It is UTC+7 and is used in Jakarta and all of western Indonesia year-round. There is no DST observed in Indonesia.

Summary

This tool displays the live current time in both London (Europe/London — GMT in winter, BST in summer) and Jakarta (Asia/Jakarta — WIB, UTC+7 year-round, no DST) side by side. Jakarta does not observe Daylight Saving Time, so the offset alternates twice a year: 7 hours ahead of London during GMT (winter) and 6 hours ahead during BST (summer). Use this tool to schedule calls with Jakarta, coordinate remote teams across the UK and Indonesia, or verify overlapping business hours.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Europe/London time using the IANA timezone database built into modern browsers.
The same moment is converted to Asia/Jakarta time (WIB, UTC+7).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — London time, Jakarta time, and the offset — refresh every second.
When London switches between GMT and BST, the displayed offset adjusts automatically from +7 to +6 hours.
