If you are scheduling a call between San Francisco and Singapore, 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 Singapore takes a little planning. San Francisco is 15 hours behind Singapore, 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 Singapore at 10 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.
