When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in San José and Cairo don't overlap on the same weekday. Cairo is 9 hours ahead of San José.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–11 AM in San José (4 PM–8 PM in Cairo) — suggest 9:00 AM San José (6:00 PM 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.
