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