When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Asunción and Osaka don't overlap on the same weekday. Osaka is 12 hours ahead of Asunción.
With some flexibility, there are two workable windows outside standard hours, depending on which side takes the early or late slot:
- 7 AM–8 AM in Asunción (7 PM–8 PM in Osaka) — suggest 7:00 AM Asunción (7:00 PM Osaka).
- 7 PM–8 PM in Asunción (7 AM–8 AM the next day in Osaka) — suggest 7:00 PM Asunción (7:00 AM Osaka).
Either is an early start or late finish for one side, but workable 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.
