Current time in Chittagong, Bangladesh

The time displayed here is the civil time for the whole region historically known in English as Chittagong and officially called Chattogram Division. The spelling changes no clock setting: every part of the division follows the national time of Bangladesh.

UTC+6 means that local clocks are six hours ahead of Coordinated Universal Time. Convert from UTC by adding six hours. If the addition passes midnight, advance the date as well. For conversion to UTC, subtract six hours and adjust the date when necessary. Chittagong has hills, coast, and busy roads, but mercifully no internal time-zone border.

One clock from the coast to the hills

The division stretches across varied terrain, yet it has only one official time. Coastal resorts, port facilities, cities, islands, and upland settlements do not apply local corrections to Bangladesh Standard Time.

Official national standard: Bangladesh Standard Time. Offset from UTC: plus six hours. Daylight saving adjustment: none currently used. Difference between places in the division: no civil-time difference.

Best notation for international plans: UTC+6. This uniformity means a local departure and arrival can be compared directly. The exception is an itinerary that crosses an international boundary into a country using another offset. In that case, use the time zone stated for each endpoint rather than geographic proximity.

Urban centers and eastern sunrise

Chattogram is the division’s largest and most prominent city. Cumilla is another major urban center, while Cox’s Bazar is a widely known coastal city. Feni, Noakhali, Brahmanbaria, Rangamati, Bandarban, and Khagrachhari are useful regional reference points. All keep UTC+6.

Because the division lies in eastern Bangladesh, sunrise by the clock generally occurs earlier here than in the country’s far west on the same date. An exact time still depends on the selected locality. Chattogram, Cox’s Bazar, and an inland hill location should not be assumed to have an identical sunrise.

Season affects both sunrise and the length of daylight. Elevation and an obstructed horizon may change when a person first sees direct sunlight, but they do not change the official astronomical calculation. Weather can hide sunrise without moving it to another time.

Pick the nearest city or use precise coordinates. Check that the requested date is local to Bangladesh. Use the sunrise field for the horizon crossing. Use dawn only when twilight is the relevant condition.

Questions and answers

Is Cox’s Bazar on the same time as Chattogram city?
Yes. Their official clocks agree.
Can sunrise differ in nearby places?
Yes. Longitude, latitude, date, and the chosen calculation location affect the reported sunrise, even within one time zone.
