When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Nagoya and Buenos Aires don't overlap on the same weekday. Buenos Aires is 12 hours behind Nagoya.
With some flexibility, there’s a workable window outside standard hours:
- 7 PM–8 PM in Nagoya (7 AM–8 AM in Buenos Aires) — suggest 7:00 PM Nagoya (7:00 AM Buenos Aires).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
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.
