The Schengen 90/180 rule, explained
Non-EU visitors can spend at most 90 days inside the Schengen Area in any rolling 180-day window. The window moves forward every single day, so your oldest days continuously 'expire', which is why the rule is so easy to miscount on paper and so worth calculating precisely.
Schengen is an immigration rule, not a tax rule, but the two interact: spend enough days in any one Schengen country and you can trigger that country's tax residency long before you hit the 90-day Schengen cap. This hub links the calculator, the explainers, and the country pages for the Schengen states.

Frequently asked questions
How does the Schengen 90/180 rule work?
On any given day, look back 180 days. You must have spent 90 or fewer days inside the Schengen Area during that window. Because the window rolls forward daily, days drop off the back as new ones are added.
Can I reset my Schengen count with a second passport?
No. The 90/180 limit applies to you as a person, not to your passport. Holding two passports does not give you two allowances, though being a citizen of a Schengen country changes the analysis entirely.
