Put in the trips you have already made. This works out the days you have used inside the rolling 180 day window, the days you have left, the last day you could stay and the first day you could go back. It runs in your browser: nothing is uploaded, and there is nothing to sign up for.
You may be in the Schengen area for 90 days in any 180 day period. The 180 days are not a fixed block that resets: they are a window that moves with you. To know whether today is legal, you look back over the last 180 days, count the days you were inside, and that number has to be 90 or lower.
The consequence people get wrong is that the window keeps sliding. A day you spent inside drops out of the count exactly 180 days after it happened, which is why days come back to you one at a time rather than all at once.
Yes, and so does the day you leave. Both are counted as whole days, however few hours you were actually there. That is the rule the European Commission applies, and it is what this calculator does.
Austria, Belgium, Bulgaria, Croatia, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden and Switzerland. They are one pot: a week in Portugal and a week in Poland is two weeks, not one week each.
Ireland is not in it, and neither is the United Kingdom. Time spent there does not use your 90 days, and it does not give them back either: only time passing does that.
If you hold a national long stay visa or a residence permit for one Schengen country, the days you spend in that country do not come off your 90. Your days in the other Schengen countries still do. This calculator counts everything you enter, so leave out the stays covered by your permit.
It is decided by the border officer of the country you are leaving from, and it ranges from a note on your file to a fine and an entry ban of one to five years. A few days over is usually the difference between an inconvenience and a problem you carry for years, which is the whole reason for counting in advance rather than at the airport.
A calculator answers for the trips you remembered to type in. The two ways people get caught out are forgetting a weekend from eight months ago, and reading a number that was right last month and is wrong today because the window has moved.
Stint is the same counting, done for you: it records which country you were in day by day in the background, keeps the whole history, and every number opens into the exact list of days behind it, so you can check it rather than trust it. It also handles the limits that are not Schengen at all: the 183 day tax year, the UK midnight test, the US substantial presence test, a visa window, or a minimum presence you have to reach to keep a residency.
