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.
NPT – Nepal Time
UTC+05:45Nepal Time (NPT, UTC+05:45) is the time zone for Nepal — one of the few offsets in the world set on a 45-minute increment.
- •Nepal Time is UTC+05:45 — a 45-minute offset, not a whole or half hour.
- •The 45-minute offset was adopted in 1986 to match Kathmandu's solar time.
- •Nepal does not observe daylight saving time.
- •Nepal is 15 minutes ahead of India, despite sharing a long open border.
Everything You Need to Know About NST and NPT Time
NST runs on Newfoundland Standard Time (NST) at UTC-03:30. NPT runs on Nepal Time (NPT) at UTC+05:45. That puts NST 9 hours 15 minutes ahead of NPT — a difference of +9h 15m at the current offsets.
In practice, when it is 9:00 AM in NST it is 6:15 PM in NPT. Midnight in NST is 9:15 AM in NPT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NST to NPT time
- Scheduling a call from NST to NPT: a 10:00 AM start in NST lands at 7:15 PM in NPT, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h 15m gap: NST and NPT 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 NPT is 6:15 PM in NST.
- Booking travel or deliveries: tracking NPT local time against NST keeps pickup windows and arrival estimates honest across the +9h 15m offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM NST" is unambiguous; "3 PM" across a +9h 15m gap is not.
- With a +9h 15m gap there is no shared 9-to-5 window, so alternate the early start: one week NST takes the early slot, the next week NPT 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 NPT (Nepal Time)
Nepal Time (NPT) runs at UTC+05:45, one of only a handful of time zones worldwide that are not a whole or half hour from UTC. Nepal set its offset to 5 hours 45 minutes ahead of UTC in 1986 to mark the country's position between the 75°E and 90°E meridians; Kathmandu's solar time sits just over 5 hours 41 minutes ahead of Greenwich, so the 45-minute offset tracks the sun more closely than either 5:30 or 6:00 would. Nepal does not observe daylight saving time, so NPT is fixed all year. The offset makes Nepal 15 minutes ahead of India Standard Time (UTC+05:30) and 2 hours 15 minutes ahead of Dubai (UTC+04:00).
Best time to call between NST and NPT
With a +9h 15m offset there is no overlap inside a normal 9 AM – 5 PM day. NPT opens at 9:00 AM NPT, which is 6:15 PM in NST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
NST and NPT have no shared working hours because of the +9h 15m gap. Teams need to alternate early starts or rely on asynchronous handovers.
NST is 9 hours 15 minutes ahead of NPT (NST UTC-03:30 → NPT UTC+05:45). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
