About Kathmandu
WikipediaKathmandu operates on Nepal Time (NPT), one of the world's unique UTC+5:45 timezones. This 15-minute offset from India makes Nepal time distinctive for global coordination.
Nepal Time (NPT) is one of only three timezones offset by 45 minutes (UTC+5:45).
Understanding the +9h 15m Gap: NST vs Kathmandu
NST runs on Newfoundland Standard Time (NST) at UTC-03:30. Kathmandu runs on Nepal Time (NPT) at UTC+05:45. That puts NST 9 hours 15 minutes ahead of Kathmandu — 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 Kathmandu. Midnight in NST is 9:15 AM in Kathmandu. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NST to Kathmandu time
- Scheduling a call from NST to Kathmandu: a 10:00 AM start in NST lands at 7:15 PM in Kathmandu, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +9h 15m gap: NST and Kathmandu 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 Kathmandu is 6:15 PM in NST.
- Watching a live event or market open: NST viewers need 6:15 PM in Kathmandu to catch a 9:00 AM start there, and 2:45 PM if the event is anchored to NST.
- 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 Kathmandu 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 Kathmandu
With a +9h 15m offset there is no overlap inside a normal 9 AM – 5 PM day. Kathmandu 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 Kathmandu 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 Kathmandu (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.
