If you are scheduling a call between Hong Kong and Shanghai, the overlap window is limited to typical business hours. When it is 9 am in Hong Kong it is 9 am in Shanghai β a workable window for scheduling. The latest reasonable overlap is around 5 pm in Hong Kong (5 pm in Shanghai). Outside this window there is effectively no good overlap for regular office hours.
Hong Kong and Shanghai have a comfortable window for a family call β no awkward alarms required. Hong Kong and Shanghai are in the same time zone, which gives you 3 hours of genuine overlap when both sides are free. Aim for between 6 pm and 9 pm in Hong Kong β that lands at 6 pm to 9 pm in Shanghai, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
