When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Hawaii Time and East Africa Time don't overlap on the same weekday. East Africa Time is 13 hours ahead of Hawaii Time.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Hawaii Time (7 AM–9 AM the next day in East Africa Time) — suggest 7:00 PM Hawaii Time (8:00 AM East Africa 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.
