Mumbai is 12.5 hours ahead of Vancouver

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

Mumbai is 12.5 hours ahead of Vancouver, so their typical working days don't line up at all. Plan on one side joining outside normal hours. A recurring slot that trades off between early mornings and late evenings usually works best. Because only Vancouver changes its clocks, the overlap above isn't fixed; expect a one-hour shift when Vancouver enters or leaves daylight saving.
