If you are scheduling a call between San Francisco and Lisbon, 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.
Scheduling a family call between San Francisco and Lisbon takes a little planning. San Francisco is 8 hours behind Lisbon, 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 Lisbon at 3 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.
