Time in Bangladesh — regions, cities and time zones

Current time in Dhaka

Bangladesh uses Bangladesh Standard Time (BST) at UTC+6, with no daylight saving. Dhaka, Chattogram, Khulna, Sylhet and every district in between share the single national clock.

One zone for 170 million people

Bangladesh covers roughly 148,000 square kilometres — dense, low-lying, and largely defined by the delta of the Ganges, Brahmaputra and Meghna. It is compact enough east to west that one time zone fits without strain, which is fortunate given the population it serves.

The UTC+6 offset places Bangladesh in an interesting position relative to its neighbours. India, which surrounds it on three sides, uses UTC+5:30 — a half-hour offset. So crossing the border in either direction shifts the clock by thirty minutes, not an hour. Myanmar, to the southeast, uses UTC+6:30, another half-hour step in the other direction.

The half-hour neighbourhood

South Asia is the world's densest concentration of non-whole-hour offsets, and Bangladesh sits at the centre of it: India — UTC+5:30, thirty minutes behind Dhaka. Nepal — UTC+5:45, a forty-five minute offset, among the rarest in the world.

Myanmar — UTC+6:30, thirty minutes ahead of Dhaka. Bangladesh — UTC+6, one of the few whole-hour offsets in its immediate region. The result is that Bangladesh is the tidy one. A meeting scheduled from Dhaka lands on a clean hour in UTC, while the same meeting scheduled from Kathmandu does not.

In a neighbourhood where the clocks argue in fifteen-minute increments, Bangladesh's whole-hour offset counts as a diplomatic achievement.

Daylight saving

Bangladesh does not currently observe daylight saving time. The offset remains UTC+6 throughout the year. The country sits between roughly 20° and 26° north, so seasonal variation in day length is modest — nothing like the swings that motivate summer time at higher latitudes. What shapes the practical day far more is the monsoon: the wet season changes how work, transport and daylight actually function, in a way no clock adjustment addresses.

Divisions and the working day

Bangladesh is organised into divisions, all on the same clock: Dhaka — the capital and the reference for national schedules, government hours and the garment industry's export timetables. Chattogram — the principal port, where shipping schedules connect BST to global logistics time.

Sylhet — the northeast, tea country, closest to the Indian state boundary. Khulna and Barishal — the southwest delta and the Sundarbans. Rajshahi and Rangpur — the drier northwest. The working week runs Sunday to Thursday for government offices, with Friday and Saturday as the weekend — which matters as much as the time zone for anyone coordinating from abroad.
