Vancouver is 10 hours behind Doha

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

Doha and Vancouver are 10 hours apart, and that gap is wide enough that their normal 9-to-5 workdays never quite touch. If you meet regularly, fix one off-hours slot and rotate it between Doha and Vancouver so the burden doesn't fall on one team. Finally, Vancouver observes daylight saving and Doha doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
