What is the Schengen 90/180 day rule?

Visitors who do not need a visa for the Schengen Area may stay a maximum of 90 days within any rolling 180-day period across the whole area combined. It is one of the most commonly misunderstood travel rules, and overstaying carries real consequences.

Two things trip people up.

It applies to the area, not to each country. Schengen includes most EU states plus a few others, and internal borders are largely unchecked. Days spent in France, Spain and Italy all count toward the same 90. Moving between them does not reset anything.

The 180-day window rolls; it does not reset on a fixed date. On any given day you must look back over the previous 180 days and count how many you were inside the area. This is why the common belief that you can leave for a day and start again is wrong. Days drop out of the count only as they age past 180 days.

Any part of a day counts as a full day, including arrival and departure days.

The European Commission publishes an official calculator, and using it before booking is worth the few minutes — the arithmetic is genuinely awkward to do in your head across several trips.

The rule applies to visitors from visa-exempt countries. Residence permits and national long-stay visas work differently, and time spent under those generally does not count.

Overstaying can lead to fines, deportation and entry bans, and is recorded.

Note also that Schengen membership and EU membership are not the same list, and the boundaries have changed over time — check the current membership rather than assuming.
