About BST
A fixed, year-round offset.
Bangladesh Standard Time (BST) keeps things simple with a single zone — Dhaka — and a fixed UTC+06:00 offset year-round, so there's no daylight saving surprises to worry about.
IANA zones · the technical identifiers
The zone that resolve to BST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

- What countries use Bangladesh Standard Time?
- Bangladesh is the only country that uses Bangladesh Standard Time, represented entirely by the Dhaka zone.
- Does Bangladesh observe daylight saving time?
- No, Bangladesh does not observe daylight saving time at all, so the clock stays on UTC+06:00 throughout the entire year.

- Bangladesh briefly experimented with daylight saving in 2009, but it was quickly discontinued — the country has since remained on a fixed UTC+06:00 offset.

- Why did Bangladesh abandon daylight saving time?
