Schengen 90/180 Calculator: How the Rolling Window Actually Works
The 90-in-180 rule is misunderstood by 70% of nomads. Here's how the rolling window works and how to track it without spreadsheets.
Non-EU passport holders can spend at most 90 days in any 180-day rolling window inside the Schengen Area. The rolling part is what trips everyone up.
Rolling window, not calendar window
Every day, you look back 180 days and count how many of those you spent in Schengen. If it exceeds 90, you've overstayed — even if you only just arrived.
Which countries count?
- Germany, France, Italy, Spain, Portugal, Netherlands, Belgium, Austria, Greece, Croatia (since 2023), Switzerland, Norway, Iceland — and 14 more.
- Ireland and Cyprus do NOT count.
- UK has been out of Schengen since Brexit.
Penalties
Overstays trigger entry bans of 1–5 years across the entire bloc. Border officers see your stamps; modern e-gates see your full history.
Track it automatically
NomadOS computes your rolling 90/180 across all Schengen countries every time you log a trip.
