Why people convert Halifax to Kathmandu time

  • Scheduling a call from Halifax to Kathmandu: a 10:00 AM start in Halifax lands at 6:45 PM in Kathmandu, so you can confirm the slot without doing the arithmetic yourself.
  • Handling a +8h 45m gap: Halifax 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 5:45 PM in Halifax.
  • Keeping family and friends in sync: knowing that 8:00 PM in Halifax is 4:45 AM in Kathmandu makes it easy to avoid calling at 3 AM.
  • Always state the zone abbreviation, not just the hour. "3:00 PM ADT" is unambiguous; "3 PM" across a +8h 45m gap is not.
  • With a +8h 45m gap there is no shared 9-to-5 window, so alternate the early start: one week Halifax takes the early slot, the next week Kathmandu 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 +8h 45m 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 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).

Business hours overlap

Halifax and Kathmandu have no shared working hours because of the +8h 45m gap. Teams need to alternate early starts or rely on asynchronous handovers.
