What is the time difference between London and Dhaka?

Dhaka (Bangladesh Standard Time, UTC+6) is 6 hours ahead of London in winter (GMT, UTC+0) and 5 hours ahead in summer (BST, UTC+1). Bangladesh does not observe Daylight Saving Time, so the offset changes only when the UK shifts its clocks in spring and autumn.

Does Dhaka observe Daylight Saving Time?

No. Bangladesh does not use Daylight Saving Time. Dhaka stays on BST (Bangladesh Standard Time, UTC+6) all year. Only London shifts its clocks, which is why the London-Dhaka gap alternates between 6 and 5 hours.

When does the offset change from 6 to 5 hours?

The UK moves clocks forward on the last Sunday in March at 01:00 GMT, entering BST (UTC+1). At that point Dhaka goes from 6 hours ahead to 5 hours ahead. The gap returns to 6 hours on the last Sunday in October at 02:00 BST when the UK reverts to GMT.

What are the best meeting times for London and Dhaka?

In winter (GMT), a 09:00–12:00 London window corresponds to 15:00–18:00 in Dhaka — good overlap. In summer (BST), a 09:00–13:00 London window corresponds to 14:00–18:00 Dhaka. Avoid scheduling after 18:00 Dhaka time as it falls outside standard business hours.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

What does BST mean for Dhaka?

For Dhaka, BST stands for Bangladesh Standard Time (UTC+6). This is different from British Summer Time, which is also abbreviated BST (UTC+1). When comparing the two cities, Dhaka's BST is always UTC+6, while London's BST only applies during summer months.

Summary

This tool displays the live current time in both London (Europe/London — GMT in winter, BST in summer) and Dhaka (Asia/Dhaka — Bangladesh Standard Time, UTC+6 year-round, no DST) side by side. Dhaka never observes Daylight Saving Time, so the offset between the two cities changes twice a year: 6 hours ahead of London in winter (GMT) and 5 hours ahead in summer (BST). Use this tool to schedule calls with Bangladesh, coordinate remote teams, or plan travel between the UK and Dhaka.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Europe/London time using the IANA timezone database built into modern browsers.
The same moment is converted to Asia/Dhaka time (Bangladesh Standard Time, UTC+6).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — London time, Dhaka time, and the offset — refresh every second.
When London switches between GMT and BST, the displayed offset adjusts automatically from +6 to +5 hours.
