What "90 in 180" really means
A C visa — the short-stay Schengen visa — allows you to be in the Schengen area for a maximum of 90 days in any 180 days. The key word here is "any": it's not two fixed half-years, but a rule that's checked afresh for every date. Formally it works like this: however many trips you plan, the total number of days spent in Schengen over the last 180 days, counting back from today, must not exceed 90.
Another detail that's often overlooked: the limit is shared across the whole Schengen area, not separate for each country. If you've spent 60 days in France, you have only 30 days left for Spain, Italy, Germany and all the other Schengen countries in the same 180-day window — a visa issued by Spain doesn't give you a separate 90-day limit of its "own".
How to count the rolling window
The right way isn't to "count six months back from your entry date" but, for each day you're interested in, to look 180 days back and add up all the days you actually spent in Schengen during that period. The window moves with the date: tomorrow it will shift a day forward, and the day that "drops off" the other end will no longer count.
That's exactly why counting in your head — with a notebook and a calendar — almost always leads to a mistake of a few days one way or the other, especially if you've made several trips in the year. It's more reliable to use the European Commission's official calculator (home-affairs.ec.europa.eu, "Short-stay calculator"): you enter all your entry and exit dates for the last 180 days, and it shows you how many days you've used and how many remain on a given date.

Take the quizWhy you can't just divide 180 by 90
The most common misconception goes like this: "90 days in Schengen, then 90 days at home — and you can go again." If the window were a fixed half-year, that would be true. But because it rolls, a trip that ended a few months ago doesn't "reset" the counter — it just gradually stops counting as it falls outside each successive 180-day window.
In practice, this means several short trips during the year are counted together, not separately: a week in March, two weeks in May and three weeks in July add up in the same window if there are fewer than 180 days between them. Anyone who plans trips "by eye", on the feeling that a lot of time has passed since the last one, risks exceeding the limit without noticing — especially if they travel often and for different lengths of time.
What happens if you overstay
Exceeding the permitted length of stay (an overstay) isn't a formality you can sort out after the fact. The consequences may include a fine, deportation and a future ban on entering the Schengen area; the exact length of such a ban is set as a result of the specific proceedings, and it would be dishonest to give a universal figure in years here — it depends on the circumstances and the country dealing with the violation.
Since 10 April 2026, the electronic Entry/Exit System (EES) has been fully operational in Schengen: instead of stamping passports, it records every border crossing, so border guards see an overstay automatically rather than counting stamps by hand. The 90/180 rule applies equally to visa holders and to visa-exempt travellers.
There's also a delayed effect: consulates take a negative visa history — including overstays — into account in future applications. This is one reason why a first Schengen visa is more often issued as single-entry or for the length of a specific trip rather than straight away as a long-term multiple-entry visa.
What to do if you plan to travel to Europe often
A multiple-entry visa (C2, C3 or multi-year) neither cancels nor increases the 90/180 limit — it only saves you from having to apply again each time, letting you cross the border several times during the visa's validity. Your total time in Schengen is still limited to the same 90 days in any 180.
If you're planning several trips in a year, it's more sensible to calculate your day balance in advance rather than after the fact — especially before booking tickets for dates that may turn out to be right on the edge of the limit. If you're unsure how to calculate the window correctly for your particular travel history, it's easier to take a short quiz or write to us — we'll look at your situation and work it out together.
What to remember
- The limit is shared across the whole Schengen area, not separate for each country.
- The 180-day window rolls: it's recalculated for every date, not tied to a fixed half-year.
- Several short trips during the year add up in the same window if there are fewer than 180 days between them.
- For an accurate calculation on specific dates, it's more reliable to use the European Commission's official calculator than to count by hand.
- A multiple-entry visa makes crossing the border easier but doesn't increase the 90-day limit.
- Overstaying affects not only your current trip but also future visa applications.
Frequently asked questions
In total. The 90/180 rule applies to the Schengen area as a whole, not to each country separately.
If you've spent 60 days in France, you'll have only 30 days left for the rest of the Schengen area — including Spain — in the same 180-day window.
The rule works with calendar days, not hours, so such a day doesn't turn into two. But it's precisely borderline cases like these — short visits, trips spanning dates — that most often lead to mistakes when counting by hand.
For an accurate result for your specific dates, it's more reliable to check with the European Commission's official calculator than to count yourself.
No, the counter doesn't reset when you leave. The 180-day window rolls: days spent in Schengen gradually stop counting only when they fall outside each successive 180-day window, not immediately after you've left the area.
The easiest way is the European Commission's official day calculator (home-affairs.ec.europa.eu, "Short-stay calculator"): you enter all your entry and exit dates for the last 180 days, and it calculates how many days you've used and how many remain on the chosen date.
