Live clocks for London and Dubai, the exact difference as it stands today, a converter preset to this pair, and the full 24-hour comparison table — daylight saving handled on both sides.
Converting from London time
The full day in London on today, with the matching time in Dubai:
| London | Dubai |
|---|
Both clocks above are read live from the IANA time-zone database built into your browser — the same rule set your phone uses. “Difference today” is not a fixed fact about this pair of cities: it is computed from the two zones’ offsets right now, which is why it can legitimately read differently if you open this page in a different month.
Dubai is 4 hours ahead of London in the British winter. Dubai never changes its clocks, so when London moves to British Summer Time (UTC+1) at the end of March, the gap narrows to 3 hours until the end of October.
The 24-hour table walks the whole of today in London, hour by hour, and prints the matching moment in Dubai — including the rows where Dubai is still on yesterday, or already on tomorrow, which are marked +1 day or −1 day. Those edge rows are exactly the ones people get wrong doing the maths in their head.
Convert any moment between 44 world time zones, with offsets and DST handled.

1:00 PM — that is 9:00 AM in London converted on a January day, when London is on GMT (UTC+0) and Dubai is on UTC+4, as it is all year. Check it any time with the converter above: the answer is worked out from the two zones’ offsets on the date you pick, so it stays right when the clocks change.
Yes, on the clock-change dates. Dubai is 4 hours ahead of London in the British winter. Dubai never changes its clocks, so when London moves to British Summer Time (UTC+1) at the end of March, the gap narrows to 3 hours until the end of October.
A comfortable overlap runs through the London morning: 9:00 AM–1:00 PM in London is 1:00–5:00 PM in Dubai. After about 2:00 PM London time you are past 6:00 PM in Dubai, outside most offices’ day.
From timestamps and the IANA time-zone database inside your browser — the live rules for each zone, including daylight-saving start and end dates and southern-hemisphere seasons where relevant. Nothing is hard-coded: open this page on a clock-change day and the clocks, the difference and the 24-hour table all follow the new offsets automatically.
Two offsets and one subtraction — the same method the converter at the top of this page runs:
Take 9:00 AM in London, on a January day, when London is on GMT (UTC+0) and Dubai is on UTC+4, as it is all year. Adding the pair’s difference for that date gives 1:00 PM in Dubai. The subtlety is that the difference itself is date-dependent for most pairs: repeat the same conversion in a month when one city has changed its clocks and the answer moves by an hour. That is why this page never prints a single fixed “the difference is X” without the word today next to it.
