NST and BDST on the World Map
The map below highlights the NST (Newfoundland Standard Time) and BDST (Bangladesh Standard Time) timezone regions across the globe.
NST – Newfoundland Standard Time
UTC-03:30Newfoundland Standard Time (NST) is a unique half-hour offset time zone in Canada, 3.5 hours behind UTC.
- •NST is one of only a few half-hour offset time zones in the world.
- •Newfoundland joined Canada in 1949 and kept its unique time zone.
- •St. John's is the easternmost city in North America.
BDST – Bangladesh Standard Time
UTC+06:00Bangladesh Standard Time (BDST, UTC+06:00) is the time zone for Bangladesh, 6 hours ahead of UTC.
- •Bangladesh uses a single time zone, UTC+06:00, across the entire country.
- •Bangladesh does not observe daylight saving time, so the offset is fixed all year.
- •Dhaka is one of the most densely populated cities globally.
- •BDST is written here to distinguish it from British Summer Time (BST).
Understanding the +9h 30m Gap: NST vs BDST
NST runs on Newfoundland Standard Time (NST) at UTC-03:30. BDST runs on Bangladesh Standard Time (BDST) at UTC+06:00. That puts NST 9 hours 30 minutes ahead of BDST — a difference of +9h 30m at the current offsets.
In practice, when it is 9:00 AM in NST it is 6:30 PM in BDST. Midnight in NST is 9:30 AM in BDST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NST to BDST time
- Scheduling a call from NST to BDST: a 10:00 AM start in NST lands at 7:30 PM in BDST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h 30m gap: NST 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 6:30 PM in NST.
- Booking travel or deliveries: tracking BDST local time against NST keeps pickup windows and arrival estimates honest across the +9h 30m offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM NST" is unambiguous; "3 PM" across a +9h 30m gap is not.
- With a +9h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week NST takes the early slot, the next week BDST does.
About NST (Newfoundland Standard Time)
Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.
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.
Best time to call between NST and BDST
With a +9h 30m offset there is no overlap inside a normal 9 AM – 5 PM day. BDST opens at 9:00 AM BDST, which is 6:30 PM in NST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
NST and BDST have no shared working hours because of the +9h 30m gap. Teams need to alternate early starts or rely on asynchronous handovers.
NST is 9 hours 30 minutes ahead of BDST (NST UTC-03:30 → BDST UTC+06:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
