The short answer: Dubai (Gulf Standard Time, UTC+4) is 4 hours ahead of London in UK winter (GMT) and 3 hours ahead in UK summer (BST). When it is 12:00 noon in London it is 3:00–4:00 PM in Dubai. The single best window is the London morning to early afternoon, which lands in the Dubai afternoon to evening — comfortably inside business hours in both cities.
Dubai and London are close enough that almost the entire working day overlaps. Because Dubai never changes its clocks, the only thing that moves is the British side: the gap is four hours in winter and three in summer. Once you know that, every conversion follows from it.
How far ahead is Dubai?
Dubai keeps a single time zone, Gulf Standard Time, at UTC+4, and it does not observe daylight saving. London runs on GMT in winter and shifts forward to BST (UTC+1) for the summer, which narrows the gap by an hour.
| Season in London | London zone | Dubai is ahead by |
|---|---|---|
| UK winter | GMT (UTC+0) | 4 hours |
| UK summer | BST (UTC+1) | 3 hours |
When it is X in London, what time is it in Dubai?
Add four hours in winter, three in summer. Here are the conversions for a typical working day, shown for both seasons.
| Time in London | In Dubai (UK winter) | In Dubai (UK summer) |
|---|---|---|
| 9:00 AM | 1:00 PM | 12:00 noon |
| 12:00 noon | 4:00 PM | 3:00 PM |
| 3:00 PM | 7:00 PM | 6:00 PM |
| 5:00 PM | 9:00 PM | 8:00 PM |
So a London team starting at 9:00 AM in summer catches Dubai right at midday, and a late-afternoon London call still lands in a sociable Dubai evening.
The best window to meet
The overlap here is generous: London morning-to-afternoon maps cleanly onto Dubai afternoon-to-evening. For a comfortable slot inside business hours on both sides, aim for the late London morning. At 10:00 AM London it is 1:00–2:00 PM in Dubai, well within the working day for everyone. Earlier London starts and mid-afternoon London times also work; you only run out of overlap once it is past early evening in Dubai.
Dubai never changes its clocks, but London springs forward to BST in late March and falls back to GMT in late October, so the gap moves between 3 and 4 hours. A recurring call set in summer will land an hour off in winter unless you adjust it. If you also coordinate with Europe, see what is CET.
Stop checking this every time
If you work between Dubai and London regularly, the seasonal hour-shift is exactly where mistakes creep in. Atlas keeps both cities side by side in your Mac menu bar, shades the hours when both sides are working, and writes any meeting to your calendar in both local times. One glance tells you whether now is a good time to call — no arithmetic, no daylight-saving slip-ups.
