Japan Standard Time (JST) is ahead of Newfoundland Time (NDT).
JST: UTC+9
NDT: UTC-2:30

When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Japan Standard Time and Newfoundland Time don't overlap on the same weekday. Newfoundland Time is 11 hours behind Japan Standard Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 PM–8 PM in Japan Standard Time (7 AM–8 AM in Newfoundland Time) — suggest 7:00 PM Japan Standard Time (7:30 AM Newfoundland 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.
