It is the rule that catches out more travellers than any other in Europe, and it sounds simpler than it is: as a visa-exempt visitor you may spend at most 90 days inside the Schengen Area within any 180-day period. We built a free Schengen 90/180 calculator — add your entry and exit dates and it shows, for any day you choose, how many of your 90 days you have used and how many remain.
Why people get it wrong
The trap is the word “rolling”. The 180-day period is not a fixed block that resets on a date — it is recalculated for every single day of your stay by looking back 180 days and counting how many you spent inside the area. Leaving for a week does not reset anything; a day only stops counting once it is more than 180 days in the past. And because the area is one zone, hopping from France to Italy to Spain does not buy you fresh days — they all share the same 90.
Entry and exit days both count
A detail that quietly costs people days: the day you arrive and the day you leave each count as a full day of presence, even if you only touch the area for a few hours. A “two-week” trip that lands late on a Friday and flies out early on a Sunday two weekends later is 16 counted days, not 14. Our calculator counts them the way a border officer does.
Who the rule does — and does not — apply to
The 90/180 limit applies to short stays by non-EU/EEA nationals: both visa-exempt passports (such as the US, UK, Canada, Australia and Japan) and holders of a Schengen short-stay type C visa. EU, EEA and Swiss citizens have free movement and are not limited by it. Crucially, a national long-stay (type D) visa or a residence permit for one Schengen country lets you live there beyond 90 days — and that time does not eat into your short-stay allowance elsewhere.
29 countries — but not Ireland or Cyprus
There are 29 Schengen states in 2026: 25 EU members plus Iceland, Liechtenstein, Norway and Switzerland. Bulgaria and Romania became full members when their land borders opened on 1 January 2025. Two EU countries are NOT in the zone — Ireland and Cyprus — so time spent there does not count toward your 90 Schengen days.
The Entry/Exit System changes the stakes
Until now, enforcement leaned on passport stamps. That is ending. The EU’s Entry/Exit System (EES) — rolling out from late 2026 — records every non-EU traveller’s crossing electronically, automatically tallying days and flagging overstays. Overstaying has always risked fines, a removal record and a re-entry ban; soon it will be far harder to do by accident and far harder to hide. Run your dates through the calculator before you book, and check the official [European Commission short-stay calculator](https://home-affairs.ec.europa.eu/policies/schengen/border-crossing/short-stay-calculator_en) as the binding reference.
