Hong Kong is 6 hours ahead of Prague

Best overlap: 8:00 AM to 12:00 PM in Prague is 2:00 PM to 6:00 PM in Hong Kong.

The overlap falls at 8:00 AM to 12:00 PM in Prague, or 2:00 PM to 6:00 PM if you're in Hong Kong. You get roughly 4 hours of shared time, so aim for the middle of that window to keep the call comfortable for both teams. Heads up: because Prague changes its clocks and Hong Kong doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
