If you are scheduling a call between Tehran and Singapore, the overlap window is limited to typical business hours. When it is 9 am in Tehran it is 1 pm in Singapore — a workable window for scheduling. The latest reasonable overlap is around 12 pm in Tehran (5 pm in Singapore). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Tehran and Singapore takes a little planning. Tehran is 4.5 hours behind Singapore, 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 Singapore 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.
