Bangladesh Standard Time (BST)

Introduction

Bangladesh Standard Time (BST) is the official time zone for Bangladesh. It operates six hours ahead of Coordinated Universal Time (UTC+06:00) and is observed uniformly across the country as a national standard. This time zone is essential for maintaining a consistent schedule for business, government, and daily activities throughout Bangladesh.

Time Zone History

The history of Bangladesh Standard Time dates back to the British Raj when Bengal adhered to Calcutta time (UTC+5:53:20) from 1890 to 1941. During World War II, the region underwent several time zone changes. On 1 October 1941, it transitioned to UTC+06:30, then to UTC+05:30 on 15 May 1942, and reverted to UTC+06:30 on 1 September 1942. After the partition of India in 1947, East Bengal (now Bangladesh) introduced Dacca Time (DACT) on 15 September 1951, which was UTC+06:00. This is the official time zone in use today.

Geographical Coverage

Bangladesh Standard Time is observed exclusively in Bangladesh. The country is located in South Asia, bordered by India to the west, north, and east, Myanmar to the southeast, and the Bay of Bengal to the south. The official time signal of BST is determined based on the 90.00° E longitude, which passes through the Harukandi Union in the Harirampur Upazila of the Manikganj District within the Dhaka Division.

Daylight Saving Time (DST)

Bangladesh does not currently observe Daylight Saving Time (DST). However, in 2009, the country briefly observed DST as a measure to address an ongoing electricity crisis. The time was advanced by one hour on the midnight of 19 June 2009, but the scheme was ultimately discontinued in 2010 due to its failure to meet its objectives.
