Bangkok is 1 hour ahead of Dhaka for most of the year: when it is 10:00 am in Dhaka it is 11:00 am in Bangkok. In offset terms Dhaka is on UTC+06:00 and Bangkok is on UTC+07:00 in January, and UTC+06:00 and UTC+07:00 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.
Neither city changes its clocks. Dhaka stays on UTC+06:00 and Bangkok stays on UTC+07:00 all year. The difference is therefore fixed for all of 2026, which makes this one of the few city pairs where a single number is the whole answer: Bangkok is always 1 hour ahead of Dhaka. Recurring meetings between the two never drift, and the table below confirms it period by period.
For arranging anything, the number that matters is the overlap. Dhaka works 09:00 to 17:00 and Bangkok works 08:30 to 17:30, which leaves 09:00 to 16:30 in Dhaka — 10:00 to 17:30 in Bangkok — as the window when both are open. That is 7.5 hours of shared working time. The working weeks differ: Dhaka works Sunday to Thursday while Bangkok 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. Offices open at 08:30 and traffic decides everything else; UTC+07:00 is fixed year-round.
The safest way to write a time for these two cities is to give both, as in "10:00 Dhaka / 11:00 Bangkok", or to give the UTC offset. Abbreviations are the trap: Dhaka is on +06 for part of the year and +06 for the rest, and the same three letters are reused in other parts of the world for entirely different offsets.
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
+1- The difference in hours that holds for most of 2026: Bangkok is 1 hour ahead of Dhaka
day shift- Whether the converted time falls on the previous, same or next calendar day in Bangkok
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 Bangkok for that moment, so a date near a daylight saving transition is handled correctly rather than with a fixed 1 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 Bangkok, and whether the two offices are open at the same moment.
Worked examples
09:00 in Dhaka
09:00 in Dhaka is 10:00 in Bangkok — inside Bangkok office hours. In 12-hour terms, 9:00 am against 10:00 am. Both offices are open at that moment, so it is a slot either side can accept.
12:00 in Dhaka
12:00 in Dhaka is 13:00 in Bangkok — inside Bangkok office hours. In 12-hour terms, 12:00 pm against 1:00 pm. Both offices are open at that moment, so it is a slot either side can accept.
16:00 in Dhaka
16:00 in Dhaka is 17:00 in Bangkok — inside Bangkok office hours. In 12-hour terms, 4:00 pm against 5:00 pm. Both offices are open at that moment, so it is a slot either side can accept.
23:00 in Dhaka, and the date problem
23:00 in Dhaka is 00:00 in Bangkok (next day). This is where conversions go wrong in writing: the time is right, the day is not, and a meeting invitation sent for "Tuesday" arrives for the wrong Tuesday. Give the date in both cities whenever the converted time is near midnight.
How to read your score
Frequently asked questions
How many hours ahead of Dhaka is Bangkok?
Bangkok is 1 hour ahead of Dhaka for most of 2026, so 09:00 in Dhaka is 10:00 in Bangkok. That difference holds for the whole year, because the two clocks either never change or change on the same dates — the table on this page confirms it period by period.
What is 2 pm Dhaka time in Bangkok?
3:00 pm, inside Bangkok office hours. In 24-hour form 14:00 in Dhaka is 15:00 in Bangkok, and that is a normal working moment in both cities.
What is the best time to call between Dhaka and Bangkok?
Anywhere between 09:00 and 16:30 Dhaka time, which is 10:00 to 17:30 in Bangkok. Both offices are open across that whole window — 7.5 hours of it. If you want one answer rather than a range, 12:45 in Dhaka is the middle of the overlap.
Is Bangkok ahead of or behind Dhaka?
Bangkok is ahead. Dhaka is at UTC+06:00 and Bangkok is at UTC+07:00 in mid-January, and UTC+06:00 and UTC+07:00 in mid-July. The clock moves forward going from Dhaka to Bangkok, which is why Bangkok reaches the end of its working day first.
Do Dhaka and Bangkok change their clocks on the same date?
Neither city changes its clocks. In 2026, Dhaka does not change its clocks at all, and Bangkok does not change its clocks at all. The difference between the two cities therefore holds all year.
What do the abbreviations for Dhaka mean?
Dhaka is on +06 in winter and +06 in summer, while Bangkok uses +07 and +07. 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 Asia/Bangkok 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 Bangkok?
No. Dhaka works Sun-Thu and Bangkok 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.
