If you are scheduling a call between Chicago 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 Chicago and Lisbon takes a little planning. Chicago is 6 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 Chicago — around 7 pm — which puts Lisbon at 1 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.
