Seattle is 10 hours behind Doha

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

Practically speaking, Doha and Seattle never share office hours; 10 hours of separation keeps their days apart. To talk live, someone has to flex: an early start in Seattle can catch the tail end of the day in Doha, or the other way round. The difference isn't constant year-round: Seattle adjusts for daylight saving while Doha holds steady.
