Portland is 11 hours behind Doha
There is no standard 8-to-6 overlap. Someone joins early or late.
Doha and Portland are too far apart in time (11 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. Watch the DST gap — when Portland changes its clocks and Doha stays the same, this window slides by an hour.
