Sources and methodology

This page is generated automatically from the guide’s central registry of sources and facts. It shows where each sensitive piece of information comes from and when it was verified.

Official sources

Methodology

1. Source first: rules and amounts are only published with a registered official source.
2. Verification date: each fact stores the date on which the source was read.
3. Review period: border and customs facts are reviewed at short intervals; attraction opening hours at even shorter ones.
4. Automatic warning: when the review period expires, the site shows that the information may be outdated instead of presenting it as current.
5. Estimates: visit times and calculator costs are editorial planning estimates, labeled as such.
6. Map: coordinates from OpenStreetMap, used as reference points.
