Vancouver is 13 hours behind Dhaka

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

Practically speaking, Dhaka and Vancouver never share office hours; 13 hours of separation keeps their days apart. To talk live, someone has to flex: an early start in Vancouver can catch the tail end of the day in Dhaka, or the other way round. The difference isn't constant year-round: Vancouver adjusts for daylight saving while Dhaka holds steady.
