Kolkata is 11.5 hours ahead of Calgary

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

Calgary and Kolkata have no natural overlap. The 11.5-hour gap is simply too large for regular working hours to meet. Treat the handoff like a relay — Calgary wraps up and leaves notes for Kolkata to pick up as their day begins. Note the seasonal wrinkle: when Calgary is on daylight saving and Kolkata isn't, the gap between them grows or shrinks by an hour.
