EST to BDT

About Eastern Time

Eastern Time is the most populous North American zone and the one most business hours are quoted in. It is UTC−5 as EST and UTC−4 as EDT. Because it changes on US dates rather than European ones, its gap to London and to Central Europe is not constant — there are two short stretches each year when it is an hour narrower than usual, and they are the reason this pair's table has more than one row.

Cities on this clock: New York, Philadelphia, Boston, Miami, Atlanta, Toronto, Montreal, Ottawa.

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 Eastern 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 10 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 11 hours ahead of Eastern 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 America/New_York and Asia/Dhaka. Nothing is looked up on a server and nothing about your visit is recorded.
