The Schengen 90/180 rule, explained

Short stays in the Schengen area are capped at 90 days of stay within any 180-day period. It applies to third-country nationals — anyone who is not a citizen of an EU or EEA country or Switzerland — whether you travel visa-free or on a short-stay type C visa.

The two numbers do different jobs. 90 is the allowance. 180 is the length of the look-back that measures it. Neither is a period you are given and then given again: there is no renewal date, no reset trip, and no fixed start.

The 180 days are counted backwards from whichever day you are asking about. Stand on a date, count back 180 days including that date, and add up the days you spent inside the area in that stretch. If the total is 90 or fewer, you are within the rule on that date.

That is what makes it a rolling window rather than a period: it moves with you. Every day that passes brings one new day into the window at the near end and drops the day from 180 days ago out at the far end. The day that drops out comes back to your allowance.

So the number of days you have left changes without you crossing a border — it changes while you sleep. Which is exactly why a figure you worked out once, in your head or in a spreadsheet, is only correct on the day you worked it out.

The counting is generous to the border and not to you:

• The day you arrive counts as a whole day, whatever time your flight lands.
• The day you leave counts as a whole day, whatever time you go.
• Every day in between counts, including days spent in a different member state — the allowance is area-wide, not country by country.
• There are no half days, and clearing passport control on a layover counts as a day in the area.

A trip from Friday to Sunday is three days, not two. Over a year of short trips, that difference alone is where an unexpected overstay usually comes from.

The Schengen area is 29 countries, and they share one allowance between them. A day in Portugal and a day in Estonia draw down the same 90.

Austria, Belgium, Bulgaria, Croatia, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden and Switzerland.

Ireland and Cyprus are in the European Union but outside the Schengen area, and the United Kingdom is outside both. Days spent in any of them do not touch your Schengen balance — each runs its own limit, counted separately. Bulgaria and Romania became full members in January 2025; Cyprus was still outside the area when this page was last updated.

Not every day you are physically in a member state is a day of short stay:

• Days spent in a country on its own national long-stay visa (type D) or on a residence permit it issued do not count against the 90 — in that country. Days in the rest of the area still do.
• Days in an EU country outside the area, such as Ireland or Cyprus, do not count at all.
• A handful of member states have older bilateral visa-waiver agreements with particular countries, which they apply on top of the area rule. They are applied inconsistently and are not something to plan a trip around without confirming with that country directly.

The exemptions are about your legal status while you are there, not about what you were doing. A holiday, a conference and a month of remote work all spend the same 90 days.

Written down, the method is four steps. Pick the day you want to know about — usually today, sometimes the last day of a trip you have not taken yet. Count back 180 days, including that day. Add up your days of stay inside that window, entry and exit days included. Subtract the total from 90.

The arithmetic is not the hard part. Keeping it correct is: every trip you add changes the answer, and so does every day that passes without one.

Work it out on your own dates

For years the count was reconstructed from passport stamps — smudged, occasionally missing, and read by an officer under time pressure. That is why so many travellers reached a border genuinely unsure what their own number was.

The European Union’s Entry/Exit System (EES) replaces the stamps with a digital record. Entries and exits at the external border are registered against your face and fingerprints, and the system works out your remaining days itself. It began a phased rollout in October 2025.

A second system, ETIAS, adds a pre-travel authorisation for visa-free travellers and is expected to follow it. Neither changes the arithmetic of 90/180 — they change how reliably it is enforced. A miscount that once passed unnoticed now meets a system that has already done the sum.

The consequences are set by the member state you are leaving from, not by the area, so they vary — but the range is consistent enough to plan against.

• A fine, issued at the border on your way out, at the officer’s discretion.
• An entry ban, usually measured in years rather than days, recorded against you area-wide.
• A record that surfaces later, in visa and residence applications long after the trip is over.

A few days over is not usually treated the same as a few months, and a documented reason — a hospital stay, a cancelled flight — is usually heard. Neither is something to rely on when the alternative is knowing the number.

Nearly every overstay story starts with one of these:

• “Leave the area for a day and the count resets.” It does not. Nothing resets the count except time — a day comes back to you 180 days after you spent it, and not before.
• “The 180 days start on 1 January.” There is no fixed period and no shared start date. The window is measured backwards from whichever day is being asked about, which is usually the day you are standing at the border.
• “90 days is about three months.” It is 90 days. Most three-month stretches are 91 or 92, and counting in months is the most common way to end up one or two days over.

This page describes how the rule is counted. It is not legal or immigration advice, and it cannot account for your nationality, your permits or a rule that changed after it was written. Visa rules change; confirm yours with the official sources for the countries you are travelling to.
