London to BDT

About United Kingdom Time

The United Kingdom is on GMT (UTC+0) for about five months and BST (UTC+1) for the rest, changing on the last Sunday in March and the last Sunday in October. Ireland keeps exactly the same clock, so every figure here applies to Dublin as well as London.

Cities on this clock: London, Lisbon, Dublin, Edinburgh, Manchester.

About Bangladesh Standard Time

Bangladesh is a fixed UTC+6, half an hour ahead of India. A single daylight-saving year in 2009 was not repeated.

Cities on this clock: Dhaka.

Watch out: BST here is Bangladesh Standard Time. The same letters are British Summer Time, which is UTC+1 — five hours apart.

How the difference is worked out

The gap between United Kingdom Time and Bangladesh Standard Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 5 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — Bangladesh Standard Time is 6 hours ahead of United Kingdom Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Europe/London and Asia/Dhaka. Nothing is looked up on a server and nothing about your visit is recorded.
