Prague is 6 hours behind Beijing
Best overlap: 2:00 PM to 6:00 PM in Beijing is 8:00 AM to 12:00 PM in Prague.
The sweet spot is 2:00 PM to 6:00 PM Beijing time, matching 8:00 AM to 12:00 PM in Prague. You've got a decent 4-hour window. Set a recurring time near 2:00 PM in Beijing (8:00 AM in Prague) and stick to it. Heads up: because Prague changes its clocks and Beijing doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
