Offset

The time difference between Nepal Time and Atlantic Time is 8.75 hours.

8.75 hours

Atlantic Time is currently observing daylight saving time; Nepal Time is not.

When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Nepal Time and Atlantic Time don't overlap on the same weekday. Atlantic Time is 9 hours behind Nepal Time.

With some flexibility, there’s a workable window outside standard hours:

  • 4 PM–8 PM in Nepal Time (7 AM–11 AM in Atlantic Time) — suggest 6:00 PM Nepal Time (9:15 AM Atlantic Time).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

This window may shift by an hour during daylight saving time.

Public holidays in 2026

National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
