Dallas is 10.5 hours behind Mumbai

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

Mumbai and Dallas have no natural overlap. The 10.5-hour gap is simply too large for regular working hours to meet. Treat the handoff like a relay — Dallas wraps up and leaves notes for Mumbai to pick up as their day begins. Bear in mind Dallas shifts for daylight saving while Mumbai stays fixed — recheck these hours after each clock change.
