Best time for work calls
If you are scheduling a call between Tehran and Seoul, the overlap window is limited to typical business hours. When it is 9 am in Tehran it is 2 pm in Seoul β a workable window for scheduling. The latest reasonable overlap is around 11 am in Tehran (5 pm in Seoul). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Scheduling a family call between Tehran and Seoul takes a little planning. Tehran is 5.5 hours behind Seoul, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Tehran β around 7 pm β which puts Seoul at 12:30 am. 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.
