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