When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Honolulu and Cairo don't overlap on the same weekday. Cairo is 13 hours ahead of Honolulu.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Honolulu (7 AM–9 AM the next day in Cairo) — suggest 7:00 PM Honolulu (8:00 AM Cairo).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
This window may shift by an hour during daylight saving time.
Note: the working week in Egypt runs Sunday–Thursday; Friday–Saturday is the weekend, so overlap on those days is limited.
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.
