Track visa-free allowance usage across a rolling window.
A rolling window means the allowance must hold for every possible window ending on the departure date, rather than for a calendar period. Days drop out of the window as they age past it. Border officers calculate this at entry, so an arriving traveller can be refused even when the planned stay itself is short.

Days remaining = allowance − days used in the window − planned stay
Entry requirements and allowance rules vary by nationality and destination and change frequently. Always verify current requirements with the destination's official immigration authority before travelling.
