About GMT (Greenwich Mean Time)

Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.

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 United Kingdom and BDST

Both United Kingdom and BDST 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

United Kingdom and BDST overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.

United Kingdom is 5 hours ahead of BDST (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.
