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