There is no standard 8-to-6 overlap. Someone joins early or late.
Honolulu and Manchester are too far apart in time (10 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. Heads up: because Manchester changes its clocks and Honolulu doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
