Cairo is 5 hours behind Shanghai
Best overlap: 1:00 PM to 6:00 PM in Shanghai is 8:00 AM to 1:00 PM in Cairo.
Aim for 1:00 PM to 6:00 PM Shanghai time — that's 8:00 AM to 1:00 PM over in Cairo. Cairo is 5 hours behind Shanghai, leaving about 5 hours of daily overlap — enough for most meetings if you don't leave them too late in the day. Keep an eye on the calendar — Cairo observes daylight saving and Shanghai doesn't, which nudges this window by an hour twice a year.
