Time Difference Between London and Dubai

Dubai is 4 hours ahead of London in winter and 3 hours ahead in summer. Dubai's clocks never change — the gap shifts because London does.

Dubai is always UTC+4. The gap changes from 4 hours to 3 hours when the UK moves to BST each spring, and back to 4 hours when the UK returns to GMT each autumn. Use the Time Zone Converter to get the precise figure for any specific date.

Why Dubai never changes its clocks

The UAE officially considered adopting daylight saving time in the past but decided against it. The reasoning: at Dubai's latitude (roughly 25° N), sunrise and sunset times don't shift as dramatically across the seasons as they do in the UK. The practical benefit of moving the clocks is smaller, and the disruption to business (particularly finance and aviation, which are central to Dubai's economy) wasn't considered worth it.

The result is that Dubai stays fixed at UTC+4 all year. When London springs forward to BST each March, the gap narrows from 4 hours to 3. When London falls back to GMT each October, the gap widens again.

The workweek difference

Beyond the time difference, there's a second scheduling quirk that trips up London–Dubai coordination: Dubai's working week is Sunday to Thursday, with Friday and Saturday as the weekend.

  • Monday to Thursday — full overlap. Both the UK and UAE are in their working week.
  • Friday — a normal working day in the UK, but the start of the weekend in Dubai. Don't schedule meetings for Friday and expect full Dubai attendance.
  • Sunday — Dubai is back at work; the UK is still on the weekend.

In practice, Monday to Thursday is the reliable window. If you need a Friday meeting with Dubai colleagues, check individually — some international businesses in Dubai operate on a Monday–Friday week, particularly those with significant European or US partnerships.

Best times to schedule a meeting

Standard UK working hours are 9 AM–5 PM. Dubai business hours are typically 9 AM–6 PM Sunday through Thursday. On a winter weekday (Monday–Thursday), the overlap looks like this:

  • 10 AM–1 PM London (winter) / 2 PM–5 PM Dubai — the most comfortable window. Both sides are past the morning start and Dubai still has time before end of day.
  • 9 AM London / 1 PM Dubai — works, though Dubai is just back from lunch.
  • 2 PM London / 6 PM Dubai — Dubai is at or past end of day; use only if Dubai is happy to run late.

In summer (BST), the window shifts an hour earlier on the London side: 10 AM–2 PM London / 1 PM–5 PM Dubai. The overlap is actually slightly more generous in summer because London is closer to Dubai's time.

For complex scheduling across more than two cities, the Meeting Planner shows everyone's working-hours block visually so you can find the least-bad column at a glance.

Travel and jet lag notes

A 3–4 hour difference produces noticeable but manageable jet lag. Common patterns:

  • London → Dubai: You arrive having "gained" 3–4 hours. Most people find eastbound travel harder — your body clock says it's earlier than local time suggests, so falling asleep at the right local time takes a day or two. Try to stay awake until at least 10 PM Dubai time on arrival day.
  • Dubai → London: You arrive having "lost" hours relative to your body clock, and it will feel like you're waking up very early for the first few days. Blackout curtains and melatonin are popular choices for the first couple of nights.

Dubai is a very common long-haul stopover — many travellers pass through on the way to Asia, Australia, or East Africa. If you're transiting, remember to set your watch to Dubai time regardless of your final destination, as airport gate times are always listed in local time.

Frequently asked questions

What time zone is Dubai in?

Dubai uses GST (Gulf Standard Time, UTC+4) year-round. The UAE does not observe daylight saving time, so Dubai's clocks never change.

Does Dubai observe daylight saving time?

No. Dubai and the UAE do not shift their clocks. The gap between London and Dubai changes not because Dubai moves, but because London shifts to British Summer Time (BST) each spring and back to GMT each autumn.

Is London 3 or 4 hours behind Dubai?

Both, depending on the time of year. In UK winter (GMT), London is 4 hours behind Dubai. In UK summer (BST), London is 3 hours behind Dubai. Dubai itself never changes.

What time is 9 AM Dubai in London?

5 AM London in UK winter (GMT). 6 AM London in UK summer (BST). For a precise answer on any specific date, use our Time Zone Converter.

Does Dubai work Monday to Friday?

No. Dubai's standard working week runs Sunday to Thursday, with Friday and Saturday as the weekend. Monday to Thursday overlaps with the UK working week. Friday is a working day in the UK but the start of the weekend in Dubai.
