London to Dubai Time Converter

Dubai is 3 hours ahead of London while London is on daylight saving time (from late March to late October), and 4 hours ahead the rest of the year. The UAE doesn’t use daylight saving time, which is why the gap moves.

The best time for a call

If both sides keep roughly 9-to-5 hours, you get 5 hours of overlap on a normal weekday: 9:00 AM to 2:00 PM in London, which is 12:00 PM to 5:00 PM in Dubai.

When the gap is 4 hours, the overlap shrinks to 4 hours: 9:00 AM to 1:00 PM in London.

Dubai stays on Gulf Standard Time (UTC+4) all year, so it’s four hours ahead of London in the UK winter and three during British Summer Time. The working days overlap comfortably: a London morning is a Dubai afternoon.

Since 2022 the UAE has worked Monday to Friday like the UK, so the old Friday headache has mostly gone. Many organisations, including government offices, still finish early on Fridays, so keep important calls to earlier in the week.

Why the time difference changes

Dubai keeps the same time all year (UTC+4). London doesn’t: its clocks go forward on the last Sunday in March and back on the last Sunday in October. Every time London changes, the gap changes with it.

Common questions

What time is it in Dubai when it’s 9 AM in London?

12:00 PM while London is on daylight saving time, and 1:00 PM the rest of the year. Pick a date in the converter above for the exact answer.

Is Dubai always 3 hours ahead of London?

No. Over the next twelve months it’s 3 hours most of the time, but it changes with the seasons: Oct 25 until Mar 28, 2027 (4 hours). That’s down to daylight saving time, explained above.

What’s a good time for a meeting between London and Dubai?

If both sides keep roughly 9-to-5 hours, you get 5 hours of overlap on a normal weekday: 9:00 AM to 2:00 PM in London, which is 12:00 PM to 5:00 PM in Dubai.

Is Dubai a day ahead of London?

For part of the day, yes. On a typical day, from about 9:00 PM in London onwards it’s already the next day in Dubai. The converter and hour-by-hour table flag this with a “next day” label.
