How the 90/180 rule works

A Schengen visa lets you stay up to 90 days in any 180-day period. Two words in that sentence cause almost all the confusion.

“Any” means the window moves. It does not reset on 1 January, on your visa’s issue date, or when you leave. On every single day you are in Europe, an officer can look back over the previous 180 days and count how many of them you spent inside the Schengen Area. If that count is over 90, you are in breach.

“Schengen” means the whole area, not one country. Thirty days in Italy, thirty in Spain and thirty in Germany is ninety days, not three separate allowances.

Both travel days count

Your day of arrival and your day of departure each count as a full day of presence, even if you land at 11pm and leave at 6am. A trip from the 1st to the 10th is ten days, not nine.

The allowance comes back gradually

Because the window rolls, days drop off the back as time passes. If you spent 30 days in Europe in March, those days stop counting against you 180 days after each of them. You do not wait for a reset; you watch the days return one at a time.

What changed with the Entry/Exit System

This rule has existed for years, but enforcement used to depend on passport stamps that were sometimes faint, missed or unreadable. Plenty of people overstayed by a few days without anyone noticing.

That has ended. The Entry/Exit System became fully operational on 10 April 2026. Every entry and exit is now recorded digitally, with your fingerprints and facial image, and the count is automatic. A border officer sees your exact position instantly.

This matters beyond the trip you are on. Overstaying makes a visa not “lawfully used”, which damages your record for future applications — including your progress towards a multiple-entry visa.

Common mistakes

• Thinking the clock resets when you leave. It does not. The window is 180 days looking backwards from wherever you are standing.
• Counting per country. The 90 days are shared across the whole area.
• Forgetting the arrival and departure days. Both count.
• Confusing visa validity with permitted stay. A five-year multiple-entry visa does not let you stay five years. It lets you make trips over five years, each subject to 90/180.
• Counting only the current trip. Short visits earlier in the window still count, including weekend trips.
• Assuming a new visa brings new days. The allowance belongs to the rolling window, not to the visa.
• Including non-Schengen countries. Days in Ireland, or in Georgia, do not count towards this limit.

If you are close to the limit

Leave earlier rather than later. A day over is an overstay, recorded digitally, and the consequences reach further than the fine or the refused entry: it affects every future application you make, to any country that asks about your immigration history.

If something outside your control keeps you in Europe beyond your limit — hospital admission, a cancelled flight, a natural disaster — contact the local immigration authority before your permitted stay ends, and keep the evidence. Extensions in cases of force majeure or humanitarian grounds exist, but they are granted by the authorities, not assumed by you.

Check against the official calculator

The European Commission publishes an official short-stay calculator. Our tool is unofficial and provided for guidance, and while we have tested its arithmetic, the Commission’s version is the one to rely on for a decision that matters.

Border officers use neither. They use the Entry/Exit System record.
