Calculators
Stay-day arithmetic you can check, running the same code the Stretch app counts with.
| Tool | What it answers |
|---|---|
| Schengen 90/180 calculator | Days used and left across the whole Schengen area, and the date you must actually be out — walking the window forward rather than subtracting, which is where a remaining-balance sum goes wrong. |
Everything here runs entirely in your browser. Nothing you type is sent anywhere, there is no account, and the arithmetic is the same module the app uses — checked against a shared conformance corpus rather than written twice.
Looking for the rules themselves rather than the count? The rulebook covers them passport by passport.
