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