Why people convert BST to Dhaka time
- Scheduling a call from BST to Dhaka: a 10:00 AM start in BST lands at 3:00 PM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both BST and Dhaka are inside the 9-to-5 working day between 9:00 AM and 12:00 PM BST time (2:00 PM–5:00 PM BDST). That is roughly 3 hours of usable overlap.
- Watching a live event or market open: BST viewers need 2:00 PM in Dhaka to catch a 9:00 AM start there, and 7:00 PM if the event is anchored to BST.
- Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a +5h gap is not.
- Block 9:00 AM–12:00 PM BST as the recurring meeting window if you work primarily from BST and need Dhaka colleagues present.
About BST (British Summer Time)
British Summer Time (BST) is the daylight saving period in the United Kingdom, when clocks move one hour forward from Greenwich Mean Time (GMT, UTC+00:00) to UTC+01:00. It runs from the last Sunday in March to the last Sunday in October. England, Scotland, Wales and Northern Ireland all follow it, along with the Isle of Man and the Channel Islands of Jersey and Guernsey. During BST, London is one hour ahead of UTC, four hours ahead of New York on Eastern Daylight Time, and five hours ahead of New York once the United States returns to Eastern Standard Time in November. BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.
About BDST (Bangladesh Standard Time)
Bangladesh Standard Time (BDST) is the single time zone used across Bangladesh, fixed at UTC+06:00 all year. Bangladesh has not observed daylight saving time since a short-lived experiment in 2009, so the gap between Bangladesh and every other zone is constant. Dhaka, the capital, is one of the most densely populated cities in the world. Because the country sits close to the middle of the UTC+06:00 band, solar noon is near 12:00 for most of the year. BDST is listed separately from British Summer Time, which shares the BST abbreviation but is UTC+01:00.
Best time to call between BST and Dhaka
Both BST and Dhaka sit inside the 9 AM – 5 PM working day between 9:00 AM–12:00 PM BST, which is 2:00 PM–5:00 PM BDST. That gives roughly 3 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
BST and Dhaka overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.
BST is 5 hours ahead of Dhaka (BST UTC+01:00 → BDST UTC+06:00). The shared working window is 9:00 AM–12:00 PM BST. Remember to re-check around daylight-saving transitions.
