What is the time difference between London and Singapore?

Singapore (SGT, UTC+8) is 8 hours ahead of London in winter (GMT, UTC+0) and 7 hours ahead in summer (BST, UTC+1). Singapore does not observe Daylight Saving Time, so the offset changes only when the UK shifts its clocks in spring and autumn.

Does Singapore observe Daylight Saving Time?

No. Singapore uses SGT (UTC+8) year-round and has not observed DST since 1982. Only London shifts its clocks, which is why the London-Singapore gap alternates between 8 and 7 hours each year.

When does the offset change from 8 to 7 hours?

The UK moves clocks forward on the last Sunday in March at 01:00 GMT, entering BST (UTC+1). At that point Singapore goes from 8 hours ahead to 7 hours ahead. The gap returns to 8 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 Singapore?

During GMT (winter), a 09:00 London call lands at 17:00 in Singapore — the end of their workday. During BST (summer), 09:00 London is 16:00 Singapore, giving a slightly better window. An 08:00–10:00 London slot is the most realistic overlap for both cities' business hours.

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.

SGT stands for Singapore Standard Time. It is UTC+8, used across Singapore year-round. There is no Singapore Daylight Saving Time designation because Singapore does not observe DST.

Summary

This tool displays the live current time in both London (Europe/London — GMT in winter, BST in summer) and Singapore (Asia/Singapore — SGT, UTC+8 year-round, no DST) side by side. Singapore does not observe Daylight Saving Time, so the offset shifts twice a year: 8 hours ahead of London in winter (GMT) and 7 hours ahead in summer (BST). Use this tool to schedule calls with Singapore, coordinate remote teams across the UK and Southeast Asia, 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/Singapore time (SGT, UTC+8).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — London time, Singapore time, and the offset — refresh every second.
When London switches between GMT and BST, the displayed offset adjusts automatically from +8 to +7 hours.
