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