Why people convert Halifax to BDST time
- Scheduling a call from Halifax to BDST: a 10:00 AM start in Halifax lands at 7:00 PM in BDST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h gap: Halifax and BDST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in BDST is 6:00 PM in Halifax.
- Coordinating a Halifax-based team with BDST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM ADT" is unambiguous; "3 PM" across a +9h gap is not.
- With a +9h gap there is no shared 9-to-5 window, so alternate the early start: one week Halifax takes the early slot, the next week BDST does.
- Halifax: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +9h gap.
About AST (Atlantic Standard Time)
Atlantic Standard Time (AST) covers Canada's Atlantic provinces (Nova Scotia, New Brunswick, Prince Edward Island, and most of Labrador), as well as several Caribbean nations. Puerto Rico and the US Virgin Islands use AST year-round without daylight saving time. The Canadian provinces switch to Atlantic Daylight Time (ADT) in summer.
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.
