Dhaka is 5 hours ahead of London for most of the year: when it is 10:00 am in London it is 3:00 pm in Dhaka. In offset terms London is on UTC+00:00 and Dhaka is on UTC+06:00 in January, and UTC+01:00 and UTC+06:00 in July. The converter above works from your browser’s own time zone data, so the figure it shows is the one in force today rather than the one that was in force when this page was written.
The difference is not constant, because only one of the two cities observes daylight saving. In 2026, London changes on 29 March and 25 October and Dhaka does not change at all. That leaves 3 distinct periods in the year, and the table below gives the exact dates. It is the short windows that catch people out: a recurring call booked in one city’s clock silently moves in the other’s.
For arranging anything, the number that matters is the overlap. London works 09:00 to 17:30 and Dhaka works 09:00 to 17:00, which leaves 09:00 to 12:00 in London — 14:00 to 17:00 in Dhaka — as the window when both are open. That is 3 hours of shared working time. The working weeks differ: Dhaka works Sunday to Thursday, so Friday is a weekend there while London is still open, and Sunday is a working day there while London is closed.
Two local details worth knowing. The City works 09:00 to 17:30, and the 08:00 market open means email is answered well before the official start. The working week is Sunday to Thursday and the clock is UTC+06:00 all year, half an hour ahead of India.
The safest way to write a time for these two cities is to give both, as in "10:00 London / 15:00 Dhaka", or to give the UTC offset. Abbreviations are the trap: London is on GMT for part of the year and BST for the rest, and the same three letters are reused in other parts of the world for entirely different offsets.
The formula
local London- The time you enter, on the London clock
offset- Each city’s UTC offset at that moment, read live from the IANA time zone database in your browser
+5- The difference in hours that holds for most of 2026: Dhaka is 5 hours ahead of London
day shift- Whether the converted time falls on the previous, same or next calendar day in Dhaka
How it works, step by step
- Enter a time in London using the 24-hour hour box and the minute box — 15:30 is hour 15, minute 30.
- Your browser reports the UTC offset in force in London and in Dhaka for that moment, so a date near a daylight saving transition is handled correctly rather than with a fixed 5 hour rule.
- The second offset minus the first gives the difference, which is added to the time you entered. A result past midnight is marked as the next or previous day, because that is where most conversion mistakes live.
- The panel also shows the current time in both cities, the date in Dhaka, and whether the two offices are open at the same moment.
Worked examples
09:00 in London
09:00 in London is 14:00 in Dhaka — inside Dhaka office hours. In 12-hour terms, 9:00 am against 2:00 pm. Both offices are open at that moment, so it is a slot either side can accept.
12:00 in London
12:00 in London is 17:00 in Dhaka — after the Dhaka working day has finished. In 12-hour terms, 12:00 pm against 5:00 pm. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.
16:30 in London
16:30 in London is 21:30 in Dhaka — after the Dhaka working day has finished. In 12-hour terms, 4:30 pm against 9:30 pm. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.
The 1 January window, when the usual answer is wrong
Between 1 January and 28 March the difference is +06:00 rather than +05:00, because one city has changed its clocks and the other has not. In that window 10:00 in London is 16:00 in Dhaka, an hour away from where a fixed-offset table would put it.
How to read your score
Frequently asked questions
How many hours ahead of London is Dhaka?
Dhaka is 5 hours ahead of London for most of 2026, so 09:00 in London is 14:00 in Dhaka. The difference changes during the daylight saving changeovers, and the table on this page lists every period in the year with its exact dates.
What is 2 pm London time in Dhaka?
7:00 pm, after the Dhaka working day has finished. In 24-hour form 14:00 in London is 19:00 in Dhaka, and that is outside working hours in Dhaka.
What is the best time to call between London and Dhaka?
Anywhere between 09:00 and 12:00 London time, which is 14:00 to 17:00 in Dhaka. Both offices are open across that whole window — 3 hours of it. If you want one answer rather than a range, 10:30 in London is the middle of the overlap.
Is Dhaka ahead of or behind London?
Dhaka is ahead. London is at UTC+00:00 and Dhaka is at UTC+06:00 in mid-January, and UTC+01:00 and UTC+06:00 in mid-July. The clock moves forward going from London to Dhaka, which is why Dhaka reaches the end of its working day first.
Do London and Dhaka change their clocks on the same date?
No. In 2026, London changes on 29 March 2026 and 25 October 2026, and Dhaka does not change its clocks at all. That is why the difference between them takes 2 different values across the year rather than one.
What do the abbreviations for London mean?
London is on GMT in winter and BST in summer, while Dhaka uses +06 and +06. Abbreviations are the least reliable way to write a time: several are ambiguous between regions, and the summer and winter forms are an hour apart. A UTC offset, or the time given in both cities, cannot be misread.
Does this converter stay correct after the clocks change?
Yes. It does not use a stored number for the difference. Each time you change a value it asks your browser for the UTC offset that Europe/London and Asia/Dhaka are on at that moment, using the IANA time zone database that ships with your operating system, and takes the difference. The tables on this page are computed from the same database for 2026.
Are the working weeks the same in London and Dhaka?
No. London works Mon-Fri and Dhaka works Sun-Thu, so part of one city’s week falls on the other’s weekend. Check the day as well as the hour before proposing a slot.
