Visa Stay Duration Calculator

Track days used against a rolling visa allowance such as Schengen.

About Visa Stay Duration Calculator

A rolling window means the allowance must be checked against every possible window ending on the departure date, not against a calendar period. Days drop out of the window as time passes, which is what restores allowance. Overstaying by even a few days can trigger multi-year entry bans, which makes conservative tracking worthwhile.

Formula

Visa Stay Duration

Days remaining = allowance − days already used in the window − planned stay

rolling window
The allowance applies to any consecutive window, not a fixed period
