When it is 09:00 in London it is 13:00 in Dubai in January and 12:00 in July. Dubai is 4 hours ahead London right now — but it is not constant: the difference is 4 hours ahead in January and 3 hours ahead in July. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in London and Dubai
The two cities side by side. The January column uses the winter offsets (London UTC+00:00, Dubai UTC+04:00); the July column uses the summer offsets (London UTC+01:00, Dubai UTC+04:00).

The time difference between London and Dubai
The difference is not constant. In January Dubai is 4 hours ahead London; in July it is 3 hours ahead London. The difference changes on Sunday, 29 March 2026 (from 4 hours ahead to 3 hours ahead) and Sunday, 25 October 2026 (from 3 hours ahead to 4 hours ahead) — those are the dates when one of the two cities changes its clocks and the other does not, or when they change on different days. Between those dates the difference is one value; outside them it is the other.
To convert a time, add the difference: 09:00 in London is 13:00 in Dubai in January and 12:00 in July; 17:00 in London — the end of the working day — is 21:00 in Dubai in January and 20:00 in July. To go the other way, subtract it: 09:00 in Dubai is 05:00 in London in January. The time difference calculator does the arithmetic for any date, and the UTC to Dubai page gives the full conversion table for Dubai.
Meeting overlap between London and Dubai
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in London's working day and shows what time they are in Dubai.
January
| London time | Dubai time | Both working? |
|---|---|---|
| 09:00 | 13:00 | Yes |
| 10:00 | 14:00 | Yes |
| 11:00 | 15:00 | Yes |
| 12:00 | 16:00 | Yes |
| 13:00 | 17:00 | Yes |

| 15:00 | 19:00 | Yes |
| 16:00 | 20:00 | Yes |
July
| London time | Dubai time | Both working? |
|---|---|---|
| 09:00 | 12:00 | No |
| 10:00 | 13:00 | No |
| 11:00 | 14:00 | No |
| 12:00 | 15:00 | No |
| 13:00 | 16:00 | No |
| 14:00 | 17:00 | No |
| 15:00 | 18:00 | No |
| 16:00 | 19:00 | No |
In January the overlap is 8 hours: 09:00, 10:00, 11:00, 12:00, 13:00, 14:00, 15:00, 16:00 London time. In July it is 0 hours: there is no hour when both cities are in their working day. The meeting planner finds the overlap for any two cities and any date, and the meeting time finder finds it for a whole team.
Daylight saving in London and Dubai
London observes daylight saving: in 2026 the clocks go forward on 29 March 2026 and back on 25 October 2026, moving the offset from UTC+00:00 to UTC+01:00.
Dubai does not observe daylight saving, so its offset of UTC+04:00 never changes.
The difference changes on Sunday, 29 March 2026 and Sunday, 25 October 2026 in 2026. On those dates, one city changes its clocks and the other does not — or they change on different days — so the difference moves by an hour. A standing meeting set in one city's local time will land an hour early or late on the other side until the second city catches up. The fix is to set the calendar event in UTC, or to check the overlap again after each change. The individual DST pages — London DST 2026 and Dubai DST 2026 — give the exact dates for each city.
Best meeting windows
The best windows in January are 09:00–17:00 in London (13:00–21:00 in Dubai). These are the hours inside both working days, so nobody is up early or late. It is a short window, so keep the meeting short and send an agenda in advance.
Calling and travel notes
When it is 09:00 in London it is 13:00 in Dubai in January; when it is 12:00 in London it is 16:00 in Dubai; when it is 17:00 in London it is 21:00 in Dubai. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling between Asia and Europe works best in the late morning in Dubai and the afternoon or evening in London. The difference is 5–9 hours, so the overlap is a few hours in the middle of the day. The main trap is daylight saving: Europe changes its clocks twice a year, and most of Asia does not, so the difference — and the overlap — moves by an hour in March and October.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in London and time in Dubai — explain each city's time zone, and the DST pages — London DST 2026 and Dubai DST 2026 — give the exact change dates.
