Prague is 7 hours ahead of Lima
Best overlap: 8:00 AM to 11:00 AM in Lima is 3:00 PM to 6:00 PM in Prague.
Target 8:00 AM to 11:00 AM in Lima, which lands at 3:00 PM to 6:00 PM for the Prague side. Prague is 7 hours ahead of Lima, so the practical overlap is about 3 hours — generous enough for meetings, tight enough to be worth booking ahead. For part of the year the maths changes: Prague observes daylight saving, Lima does not, shifting the overlap by an hour.
