Honolulu is 13 hours behind Cairo

There is no standard 8-to-6 overlap. Someone joins early or late.

Cairo and Honolulu are too far apart in time (13 hours) for their workdays to line up during regular hours. For anything urgent, agree on an early-morning or late-night bridge hour in advance so nobody's caught off guard. Because only Cairo changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Cairo enters or leaves daylight saving.
