If you are scheduling a call between London and Shanghai, the overlap window is limited to typical business hours. When it is 9 am in London it is 4 pm in Shanghai β a workable window for scheduling. The latest reasonable overlap is around 10 am in London (5 pm in Shanghai). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between London and Shanghai takes a little planning. London is 7 hours behind Shanghai, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in London β around 7 pm β which puts Shanghai at 2 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.
