How the Schengen 90/180-day rule counts days

The standard Schengen short-stay calculation allows no more than 90 days in any rolling 180-day period. Both the entry date and the exit date count as days of stay.

The window moves every day

There is no single six-month block that resets automatically. For any date you inspect, count that date and the previous 179 calendar days. The total Schengen stay days inside that window must not exceed 90.

A same-day entry and exit counts as one day. Several trips are added together. As old stay days move outside the rolling window, days can become available again.

Check the whole planned stay

Do not look only at the entry date. A trip can be within the limit on arrival and exceed it before departure. Check every date in the planned range, or use a calculator that does this.

The Schengen Days Calculator counts entered stays and flags the first entered date above 90. It rejects overlapping ranges so the same day is not counted twice.

Know what the calculator does not decide

The standard count may not describe days covered by a long-stay visa, residence permit, bilateral arrangement or another special status. Visa validity, allowed entries and passport rules are separate questions.

Use the European Commission calculator for confirmation and contact the authority handling the visa or border question when an exception may apply. Keep a copy of the official guidance used for a time-sensitive decision.
