How it's calculated
1
For each kraj (plus Prague), school holiday dates are loaded — the source is the
OpenHolidays API.
2
For each calendar week, we count which krajs + Prague are on holiday — weighted by their importance as a source market. Where most guests come from counts the most.
3
The classification is peak-anchored: the densest week sets the benchmark, every other week is measured against it. That keeps the calendar comparable across years.
The calendar reflects holiday demand, not your actual bookings. Regional public holidays, trade fairs, events and weather come on top. A guideline, not a guarantee.
We currently source each kraj (plus Prague) from a single source only (OpenHolidays). We don't yet have a second, independent source to cross-check against — the dates are plausible but not (yet) cross-verified.
