What Is the Schengen 90/180 Rule?
If you are a passport holder from a visa-exempt nation (such as the United States, United Kingdom, Canada, Australia, or New Zealand), you are entitled to enter the Schengen Area for up to 90 days in any 180-day period without applying for a visa.
The most common point of confusion is assuming the 180-day period is tied to the calendar year (like January to June) or that leaving the zone for a weekend resets the clock.
It does not. The rule uses a continuous rolling window.
How the Rolling Window Actually Works
On every single calendar day you are physically inside the Schengen zone, border authorities look back at the preceding 180 calendar days (today plus the previous 179 days).
If the total number of days you spent in any Schengen member state within that 180-day window exceeds 90, you are legally in an overstay situation.
What Countries Are in Schengen?
As of 2026, 29 European countries form the Schengen Area, including Portugal, Spain, France, Germany, Italy, Austria, Czechia, Hungary, Poland, Slovakia, Slovenia, Switzerland, and the Nordic nations.
