Lima is 7 hours behind Prague
Best overlap: 3:00 PM to 6:00 PM in Prague is 8:00 AM to 11:00 AM in Lima.
If you set up a recurring sync, 3:00 PM to 6:00 PM in Prague (8:00 AM to 11:00 AM in Lima) is the natural home for it. You share roughly 3 hours a day. That's enough for regular meetings, but treat the window as prime time and guard it. Finally, Prague observes daylight saving and Lima doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
