Best time for work calls
If you are scheduling a call between Guangzhou and Seoul, the overlap window is limited to typical business hours. When it is 9 am in Guangzhou it is 10 am in Seoul β a workable window for scheduling. The latest reasonable overlap is around 4 pm in Guangzhou (5 pm in Seoul). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Guangzhou and Seoul have a comfortable window for a family call β no awkward alarms required. Guangzhou is 1 hour behind Seoul, which gives you 2 hours of genuine overlap when both sides are free. Aim for between 6 pm and 8 pm in Guangzhou β that lands at 7 pm to 9 pm in Seoul, 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.
