About Schengen Days
Short answer: Schengen Days is a free calculator for the Schengen 90/180-day rule. It runs in your browser, keeps your trips on your device, and works offline once loaded.
How it counts
- For any date, the window is that date and the 179 days before it (180 days in total).
- Entry and exit days both count. Overlapping trips are counted once per day.
- Only the 29 Schengen countries count. Ireland, Cyprus, the UK and others are stored but count zero.
- "Last day you can stay" and future-trip checks are worked out day by day, because old days keep dropping out.
The counting code is tested against worked examples, including leap years, year ends, overlapping trips and the classic "90 in, 90 out" case, with expected answers worked out independently.
Your data
Your trips are saved in your browser on this device. There are no ads, no trackers and no analytics scripts. You can export your trips to a file and import them on another device; optional sign-in syncs them between devices.
How facts are checked
The guides cite official EU sources — the European Commission and the EU's Travel to Europe site — and national government travel advice. Each page shows when it was last checked.
Disclaimer
This is a planning aid, not an official calculation. Border officers make their own count from your passport stamps and entry records, and their calculation is the one that governs. It assumes the standard 90/180 short-stay rule. If you hold a residence permit or a long-stay national (type D) visa for a Schengen country, different rules apply that this tool does not model.
