Why people convert Dhaka to Dublin time
- Scheduling a call from Dhaka to Dublin: a 10:00 AM start in Dhaka lands at 5:00 AM in Dublin, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Dhaka and Dublin are inside the 9-to-5 working day between 2:00 PM and 5:00 PM BDST time (9:00 AM–12:00 PM IST). That is roughly 3 hours of usable overlap.
- Watching a live event or market open: Dhaka viewers need 4:00 AM in Dublin to catch a 9:00 AM start there, and 5:00 AM if the event is anchored to Dhaka.
- Always state the zone abbreviation, not just the hour. "3:00 PM BDST" is unambiguous; "3 PM" across a -5h gap is not.
- Block 2:00 PM–5:00 PM BDST as the recurring meeting window if you work primarily from Dhaka and need Dublin colleagues present.
- Dublin: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
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.
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.

Business hours overlap
