About Time Zone Converter · বিস্তারিত
Pick a date and time, and the converter shows that same moment in every city you have added, with weekday, date and GMT offset. It offers 14 cities, including Dhaka, Dubai, Riyadh, London, New York, Los Angeles and Sydney, and daylight saving time is applied automatically.
Scheduling across Bangladesh, the Gulf and the West is tricky because the gaps move. Dhaka and Dubai never change their clocks, so Dhaka is always 2 hours ahead of Dubai. London and New York switch to summer time, so their distance from Dhaka is one hour shorter for part of the year. The converter uses your browser's built-in time zone database, which already knows those switch dates.
The reference time is entered in your own local time. Every card then shows the city name, the IANA zone id (such as Asia/Dhaka) and the offset that applies on that date, for example GMT+6 or GMT-5.

When it helps · কখন কাজে লাগে
- Calls with family abroad
- Someone in Dhaka can find a time that is evening for parents at home and after work for a brother in Riyadh or Dubai.
- Freelancers with overseas clients
- Check what 10:00 AM in New York means in Dhaka before agreeing to a call, including in the weeks when US clocks change.
- Remote teams
- Keep London, Karachi, Kolkata and Singapore on one screen to plan a meeting that does not land at midnight for anyone.
Example: 3:00 PM in Dubai on 10 December 2026
Dubai is on GMT+4, so the same moment is 5:00 PM in Dhaka (GMT+6), 11:00 AM in London (GMT+0) and 6:00 AM in New York (GMT-5). In July, with London and New York on summer time, 3:00 PM in Dubai is 12:00 noon in London and 7:00 AM in New York, while Dhaka stays at 5:00 PM.
