When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Nagoya and Greenwich Mean Time don't overlap on the same weekday. Greenwich Mean Time is 8 hours behind Nagoya.
With some flexibility, there’s a workable window outside standard hours:
- 3 PM–8 PM in Nagoya (7 AM–12 PM in Greenwich Mean Time) — suggest 5:00 PM Nagoya (9:00 AM Greenwich Mean 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.
