San Diego is 12.5 hours behind Mumbai

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

San Diego is 12.5 hours behind Mumbai, 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. Just remember San Diego changes its clocks for daylight saving and Mumbai doesn't, so confirm the overlap whenever the seasons turn.
