When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Phoenix and Osaka don't overlap on the same weekday. Osaka is 16 hours ahead of Phoenix.
With some flexibility, there’s a workable window outside standard hours:
- 3 PM–8 PM in Phoenix (7 AM–12 PM the next day in Osaka) — suggest 5:00 PM Phoenix (9:00 AM Osaka).
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.
