Bangladesh uses a single time zone, and this guide covers them all: the offset in each city, the daylight saving dates, the best time to call from New York or London, and how to convert any time. The city covered here is Dhaka.

Time zones in Bangladesh

City IANA time zone Offset in January 2026 Offset in July 2026 Daylight saving?
Dhaka Asia/Dhaka UTC+06:00 UTC+06:00 No

With one time zone, Bangladesh is simple: the whole country is on Asia/Dhaka, UTC+06:00 from UTC all year. There is no internal time difference to worry about — a meeting scheduled for 10am in Dhaka is 10am everywhere in the country. The only question is the difference from the rest of the world, and the table above gives it for January and July.

Daylight saving in Bangladesh

None of the cities covered here observes daylight saving — Bangladesh stays on the same offset all year. Dhaka: Bangladesh last observed daylight saving in 2009, as a one-year energy-saving experiment. It has not been used since. The advantage is simplicity: the offset you learn is the offset all year, and a meeting scheduled in January is at the same time in July.

How to convert a time to Bangladesh

Take 3pm in London. In January, London is UTC+00:00 and Dhaka is UTC+06:00, so 3pm in London is 9:00 pm in Dhaka. In July, London is UTC+01:00 and Dhaka is UTC+06:00, so 3pm in London is 8:00 pm in Dhaka. The answer is the same in July as in January, because neither place changes its offset — Dhaka does not observe daylight saving. The time zone converter does this for any two cities and any date, and the UTC converter converts from UTC.

The best time to call Bangladesh

The overlap of a 9am–5pm working day between Dhaka and New York is none in January 2026; between Dhaka and London it is 2 hours. The best time to call is mid-morning in the city further east and late morning in the city further west — the overlap of the two best parts of the day. The meeting planner shows the overlap for any set of cities.

The time in Bangladesh through the year

The offset of Dhaka month by month in 2026 — the local time when it is 12:00 UTC on the 15th of each month:

Month UTC offset Local time at 12:00 UTC
January UTC+06:00 6:00 pm
February UTC+06:00 6:00 pm
March UTC+06:00 6:00 pm
April UTC+06:00 6:00 pm
May UTC+06:00 6:00 pm
June UTC+06:00 6:00 pm
July UTC+06:00 6:00 pm
August UTC+06:00 6:00 pm
September UTC+06:00 6:00 pm
October UTC+06:00 6:00 pm
November UTC+06:00 6:00 pm
December UTC+06:00 6:00 pm

Dhaka stays on the same offset all twelve months, because it does not observe daylight saving — the table is the same in January and in July, and there is no clock change to remember. The world clock for Dhaka shows the live time and the offset in effect today.

Bangladesh and the rest of the world

The time difference from Dhaka to six major cities, in January and in July 2026:

City Difference in January Difference in July
New York 11 hours ahead 10 hours ahead
London 6 hours ahead 5 hours ahead
Paris 5 hours ahead 4 hours ahead
Tokyo 3 hours behind 3 hours behind
Sydney 5 hours behind 4 hours behind
Dubai 2 hours ahead 2 hours ahead

The differences change between January and July wherever one of the two cities observes daylight saving and the other does not — or wherever they change on different dates. The time zone converter gives the difference for any date, so a conversion done for January is not reused for July without checking.

Calling Bangladesh from London

In January, the working hours of Dhaka and London overlap between 9:00 am and 11:00 am London time — that is the window in which a call falls inside both working days. The best time inside the window is usually the middle of it, when both sides are mid-morning or early afternoon rather than at the edge of the working day. Outside the window, one side is either not yet at work or already finished, so the call has to be early morning or late evening for someone.
