Best time for work calls
If you are scheduling a call between San Francisco and Seoul, 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 San Francisco and Seoul takes a little planning. San Francisco is 16 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 San Francisco — around 7 pm — which puts Seoul at 11 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.
