Prague is 6 hours behind Taipei
Best overlap: 2:00 PM to 6:00 PM in Taipei is 8:00 AM to 12:00 PM in Prague.
Both offices are open during 2:00 PM to 6:00 PM Taipei time, which is 8:00 AM to 12:00 PM in Prague. You get roughly 4 hours of shared time, so aim for the middle of that window to keep the call comfortable for both teams. The window above shifts seasonally: Prague keeps daylight saving while Taipei ignores it.
