The Schengen 90/180 rule, explained simply
What the 90/180 rule actually means, how the rolling window is counted, and how to avoid an accidental overstay.
What the rule says
Visa-exempt visitors can spend up to 90 days inside the Schengen area within any rolling 180-day period. It's not per-country and not per-calendar-year — the whole zone shares one budget, and the window slides with every day.
How the rolling window works
On any given day, count back 180 days and add up the days you were physically present in Schengen. If that total would exceed 90, you can't be there that day. Days of entry and exit both count as full days.
Avoiding an overstay
The 2026 EES system now logs entries and exits electronically, so manual stamp-counting is over — overstays are caught automatically and can trigger bans. Track every trip in a counter, and if you need longer, look at a national long-stay visa or a digital-nomad permit.
