The Schengen 90/180 rule, explained
How the Schengen Area's rolling 90-days-in-180 limit really works, why counting from your entry date gets it wrong, and how to know when your next day frees up.
If you visit Europe on a passport that doesn’t need a Schengen visa for short stays (US, UK, Canadian, Australian and many others), you can stay in the Schengen Area for up to 90 days in any 180-day period. It sounds simple. It’s the most commonly miscounted rule in travel.
It’s a rolling window, not a calendar
There’s no reset on January 1, and no reset when you leave. On any given day, look back over the previous 180 days, including today, and count every day you spent anywhere in the Schengen Area. If that number would go above 90, you’re over.
That’s why “I was out for a month, so I’m fine” doesn’t work. Days you spent in Schengen five months ago still count until they fall out of the window.
Entry and exit days both count
A day on which you were in the Schengen Area for any part of it counts as a full day. Fly into Paris at 11pm on the 1st and out of Lisbon at 6am on the 10th, and that’s ten days, not eight.
One area, not separate countries
The 90 days are shared across every Schengen country. Two months in Spain and a month in Italy is 90 days. Schengen includes most EU members plus Iceland, Liechtenstein, Norway and Switzerland. Ireland and Cyprus are in the EU but not in Schengen, so days there don’t count toward the 90.
Some countries have bilateral agreements that allow longer stays for certain nationalities. Those are exceptions with their own conditions, so check before relying on one.
When can you come back?
The useful question is usually not “how many days have I used?” but “when does my next day free up?” Each day you spent in the window drops out exactly 180 days later. If you have used all 90, you can return once enough of your oldest days have rolled off to cover the trip you’re planning.
Diego does this for you: its Schengen tracker counts every Schengen day in the rolling window and shows the date your oldest day rolls off. It’s free on every plan.
Overstays are recorded
The EU’s Entry/Exit System now records entries and exits of non-EU travelers electronically, so overstays are easier to detect than they were with passport stamps. Penalties for overstaying range from fines to entry bans.

Common questions
How does the Schengen 90/180 rule work?
Travelers who don't need a visa for short stays can spend up to 90 days in any 180-day period in the Schengen Area. On any day, look back over the previous 180 days, including today, and count every day you spent in the area; the total must not exceed 90.
Does the 90/180 count reset when I leave the Schengen Area?
No. There is no reset on leaving or on January 1. Each day you spent in the area stays in your count until it falls out of the rolling 180-day window, exactly 180 days later.
Do days in different Schengen countries add together?
Yes. The 90 days are shared across every Schengen country, so two months in Spain and a month in Italy uses all 90. Days in Ireland and Cyprus, which are in the EU but not in Schengen, don't count.
When can I return to the Schengen Area after using 90 days?
Once enough of your oldest days have rolled out of the 180-day window to cover the trip you're planning. Each day drops out 180 days after it was spent.
Are overstays in the Schengen Area recorded?
Yes. The EU's Entry/Exit System records the entries and exits of non-EU travelers electronically, so overstays are easier to detect, and penalties range from fines to entry bans.
