London is 5 hours behind Dhaka for most of the year: when it is 10:00 am in Dhaka it is 5:00 am in London. In offset terms Dhaka is on UTC+06:00 and London is on UTC+00:00 in January, and UTC+06:00 and UTC+01:00 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, Dhaka does not change at all and London changes on 29 March and 25 October. 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. Dhaka works 09:00 to 17:00 and London works 09:00 to 17:30, which leaves 14:00 to 17:00 in Dhaka — 09:00 to 12:00 in London — as the window when both are open. That is 3 hours of shared working time. The working weeks differ: Dhaka works Sunday to Thursday while London works Monday to Friday, which leaves three shared days at each end of the week and two mismatched ones.
Two local details worth knowing. The working week is Sunday to Thursday and the clock is UTC+06:00 all year, half an hour ahead of India. The City works 09:00 to 17:30, and the 08:00 market open means email is answered well before the official start.
Write the invitation in both clocks. "10:00 Dhaka / 05:00 London" removes the ambiguity that abbreviations introduce — Dhaka alone is read as +06 in winter and +06 in summer, and calendar software will happily convert one into the other without telling you.
The formula
local Dhaka- The time you enter, on the Dhaka 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: London is 5 hours behind Dhaka
day shift- Whether the converted time falls on the previous, same or next calendar day in London
How it works, step by step
- Enter a time in Dhaka 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 Dhaka and in London 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 London, and whether the two offices are open at the same moment.
Worked examples
09:00 in Dhaka
09:00 in Dhaka is 04:00 in London — the middle of the night in London. In 12-hour terms, 9:00 am against 4:00 am. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.
12:00 in Dhaka
12:00 in Dhaka is 07:00 in London — before the working day starts in London. In 12-hour terms, 12:00 pm against 7:00 am. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.
16:00 in Dhaka
16:00 in Dhaka is 11:00 in London — inside London office hours. In 12-hour terms, 4:00 pm against 11:00 am. Both offices are open at that moment, so it is a slot either side can accept.
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 Dhaka is 04:00 in London, an hour away from where a fixed-offset table would put it.
How to read your score
Frequently asked questions
How many hours behind Dhaka is London?
London is 5 hours behind Dhaka for most of 2026, so 09:00 in Dhaka is 04:00 in London. 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 Dhaka time in London?
9:00 am, inside London office hours. In 24-hour form 14:00 in Dhaka is 09:00 in London, and that is a normal working moment in both cities.
What is the best time to call between Dhaka and London?
Anywhere between 14:00 and 17:00 Dhaka time, which is 09:00 to 12:00 in London. Both offices are open across that whole window — 3 hours of it. If you want one answer rather than a range, 15:30 in Dhaka is the middle of the overlap.
Is London ahead of or behind Dhaka?
London is behind. Dhaka is at UTC+06:00 and London is at UTC+00:00 in mid-January, and UTC+06:00 and UTC+01:00 in mid-July. The clock moves back going from Dhaka to London, which is why Dhaka reaches the end of its working day first.
Do Dhaka and London change their clocks on the same date?
No. In 2026, Dhaka does not change its clocks at all, and London changes on 29 March 2026 and 25 October 2026. That is why the difference between them takes 2 different values across the year rather than one.
What do the abbreviations for Dhaka mean?
Dhaka is on +06 in winter and +06 in summer, while London uses GMT and BST. 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 Asia/Dhaka and Europe/London 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 Dhaka and London?
No. Dhaka works Sun-Thu and London works Mon-Fri, 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.
