When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Buenos Aires and Fukuoka don't overlap on the same weekday. Fukuoka is 12 hours ahead of Buenos Aires.
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 Buenos Aires (7 PM–8 PM in Fukuoka) — suggest 7:00 AM Buenos Aires (7:00 PM Fukuoka).
- 7 PM–8 PM in Buenos Aires (7 AM–8 AM the next day in Fukuoka) — suggest 7:00 PM Buenos Aires (7:00 AM Fukuoka).
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.
