90/180-Day Rule

The 90/180-day rule caps how long you can stay in a region as a short-stay visitor. The most famous version applies to the Schengen Area, where many non-EU travellers may be present for no more than 90 days within any 180-day period. It’s how short stays get measured before a residence-based status is needed.

The part people miss is the word “rolling.” This isn’t a calendar that resets on a fixed date. For any given day, the authorities look back over the previous 180 days and count how many you spent inside the zone. Go over 90 and you’re past the limit. Days you spent abroad free up again as they pass the 180-day mark, so your allowance shifts a little every day.

This matters most when you move countries or string trips together. Two long visits a few months apart can quietly push you over, even though each one alone felt fine. Counting in your head is where mistakes happen, so track your entry and exit dates carefully, or use a tool like the schengen-counter to see your remaining days. Crossing a border just to restart the clock, often called a visa run, usually does not work here, because the rolling window keeps counting your earlier days regardless.

If you plan to stay longer than the short-stay limit allows, that’s the signal to look at a residence permit or another long-stay route rather than stacking visits. The exact rule, the start date of your count, and how non-Schengen countries apply their own 90/180 schemes can all vary by country, so check the specifics for your destination. This is general information, not advice; confirm the details with the official source or an immigration professional before you book.

Where you’ll meet this

• A border officer scanning your passport and counting your recent days before stamping you in or turning you back.
• Planning a multi-month trip and realising an earlier visit still eats into your remaining 90 days.
• Reading the entry requirements on an embassy or government visa page before you apply for a longer stay.
