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.
Cities currently on BST

- What countries use Bangladesh Standard Time?
- Bangladesh is the only country that uses Bangladesh Standard Time, represented entirely by the Asia/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.
- Has Bangladesh ever observed daylight saving time?
- 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.
- How does Bangladesh's single timezone affect daily life?
- With just one timezone covering the entire country, scheduling across Bangladesh is straightforward — everyone from Chittagong to Khulna shares the same clock time.
- What is the UTC offset for Bangladesh Standard Time?
- Bangladesh Standard Time is set at UTC+06:00, which it has maintained consistently since the end of 2009.
- What is the abbreviation for Bangladesh Standard Time?
- The standard abbreviation is +06, reflecting the fixed UTC+06:00 offset with no daylight saving adjustments.
- Why did Bangladesh abandon daylight saving time?
- The 2009 daylight saving experiment was rolled back largely because the country's proximity to the equator means daylight hours don't vary enough throughout the year to justify the clock change.
