Calgary is 11.5 hours behind Kolkata

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

Practically speaking, Kolkata and Calgary never share office hours; 11.5 hours of separation keeps their days apart. To talk live, someone has to flex: an early start in Calgary can catch the tail end of the day in Kolkata, or the other way round. A quick caveat — Calgary's clocks move for daylight saving and Kolkata's don't, so the times here are right for only part of the year.
