What is the time difference between London and Dubai?

Dubai (GST, UTC+4) is 4 hours ahead of London in winter (GMT, UTC+0) and 3 hours ahead in summer (BST, UTC+1). The UAE does not observe Daylight Saving Time, so the offset changes only when the UK shifts its clocks in spring and autumn.

Does Dubai observe Daylight Saving Time?

No. The United Arab Emirates does not use Daylight Saving Time. Dubai stays on GST (UTC+4) all year. Only London shifts its clocks, which is why the London-Dubai gap alternates between 4 and 3 hours.

When does the offset change from 4 to 3 hours?

The UK moves clocks forward on the last Sunday in March at 01:00 GMT, entering BST (UTC+1). At that point Dubai goes from 4 hours ahead to 3 hours ahead. The gap returns to 4 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 Dubai?

In winter (GMT), a 09:00–14:00 London window corresponds to 13:00–18:00 in Dubai — solid overlap. In summer (BST), a 09:00–15:00 London window corresponds to 12:00–18:00 Dubai. Avoid scheduling after 18:00 Dubai time as it falls outside standard 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.

GST stands for Gulf Standard Time. It is UTC+4, used across the United Arab Emirates (including Dubai and Abu Dhabi) year-round. There is no Gulf Daylight Saving Time because the UAE does not observe DST.

Summary

This tool displays the live current time in both London (Europe/London — GMT in winter, BST in summer) and Dubai (Asia/Dubai — GST, UTC+4 year-round, no DST) side by side. Dubai never observes Daylight Saving Time, so the offset between the two cities changes twice a year: 4 hours ahead of London in winter (GMT) and 3 hours ahead in summer (BST). Use this tool to schedule calls with the UAE, coordinate remote teams, or plan travel between the UK and Dubai.

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/Dubai time (GST, UTC+4).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — London time, Dubai time, and the offset — refresh every second.
When London switches between GMT and BST, the displayed offset adjusts automatically from +4 to +3 hours.
