If you are scheduling a call between Warsaw and Kolkata, the overlap window is limited to typical business hours. When it is 9 am in Warsaw it is 12 pm in Kolkata — a workable window for scheduling. The latest reasonable overlap is around 1 pm in Warsaw (5 pm in Kolkata). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Warsaw and Kolkata takes a little planning. Warsaw is 3.5 hours behind Kolkata, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Warsaw — around 7 pm — which puts Kolkata at 10:30 pm. Someone will need to stretch a little, but at least no one's setting a middle-of-the-night alarm. Weekends tend to give the most flexibility if you can agree on a time in advance.
