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