Cairo is 1 hour ahead of Geneva
Best overlap: 8:00 AM to 5:00 PM in Geneva is 9:00 AM to 6:00 PM in Cairo.
Both offices are open during 8:00 AM to 5:00 PM Geneva time, which is 9:00 AM to 6:00 PM in Cairo. Scheduling is forgiving here: with 9 hours of overlap, a missed slot just means picking another one the same day.
