If you are scheduling a call between Kolkata and Sydney, the overlap window is limited to typical business hours. When it is 9 am in Kolkata it is 1 pm in Sydney — a workable window for scheduling. The latest reasonable overlap is around 12 pm in Kolkata (5 pm in Sydney). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Kolkata and Sydney takes a little planning. Kolkata is 4.5 hours behind Sydney, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Kolkata — around 7 pm — which puts Sydney at 11:30 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.
