Offset

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

8.75 hours

Atlantic Time (ADT) is behind Nepal Time (NPT).

ADT: UTC-3

NPT: UTC+5:45

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 Atlantic Time and Nepal Time don't overlap on the same weekday. Nepal Time is 9 hours ahead of Atlantic Time.

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

  • 7 AM–12 PM in Atlantic Time (3 PM–8 PM in Nepal Time) — suggest 9:00 AM Atlantic Time (5:45 PM Nepal 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.
