Why people convert Dublin to Dhaka time
- Scheduling a call from Dublin to Dhaka: a 10:00 AM start in Dublin lands at 3:00 PM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Dublin and Dhaka are inside the 9-to-5 working day between 9:00 AM and 12:00 PM IST time (2:00 PM–5:00 PM BDST). That is roughly 3 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Dublin is 1:00 AM in Dhaka makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +5h gap is not.
- Block 9:00 AM–12:00 PM IST as the recurring meeting window if you work primarily from Dublin and need Dhaka colleagues present.
- Dublin: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +5h gap.
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.
