Best time for work calls
If you are scheduling a call between Tehran and San Francisco, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
Best time for family calls
Scheduling a family call between Tehran and San Francisco takes a little planning. Tehran is 10.5 hours ahead of San Francisco, 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 San Francisco at 8:30 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.
