Casablanca is 2 hours behind Cairo
Best overlap: 10:00 AM to 6:00 PM in Cairo is 8:00 AM to 4:00 PM in Casablanca.
Target 10:00 AM to 6:00 PM in Cairo, which lands at 8:00 AM to 4:00 PM for the Casablanca side. Casablanca is 2 hours behind Cairo, but you'd hardly notice — 8 hours of shared hours makes this feel like working in neighbouring time zones. Daylight saving complicates things slightly: Cairo observes it, Casablanca doesn't, so the difference flexes by an hour part of the year.
