Best time for work calls
If you are scheduling a call between Guangzhou and Kolkata, the overlap window is limited to typical business hours. When it is 11 am in Guangzhou it is 9 am in Kolkata — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Guangzhou (2 pm in Kolkata). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Scheduling a family call between Guangzhou and Kolkata takes a little planning. Guangzhou is 2.5 hours ahead of Kolkata, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Guangzhou — around 7 pm — which puts Kolkata at 4:30 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.
