Schengen 90/180 day calculator
You can spend at most 90 days in any rolling 180-day period in the Schengen area - entry and exit days both count, the whole area shares one allowance, and leaving does not reset anything. Enter your trips below to see exactly where you stand, the longest stay you could start today, and the earliest date your next trip fits.
Free, no signup - your dates never leave this browser. Built for post-Brexit UK passport holders, though the arithmetic is the same for any visa-free visitor.
How the 90/180 rule actually works
The rule trips people up because the window rolls. On every day of a stay, look back exactly 180 days and count every day you were inside the Schengen area - that count must never go above 90. There is no reset on leaving and no calendar quarters: a day simply stops counting once it is more than 180 days ago.
A worked example: you spend 40 days in Spain in April-May, then 50 days around France and Italy in June-July. Each trip is comfortably under 90 - but they sit in the same 180-day window, so by the end of the second trip you have used 90 of 90. If you tried to add even a weekend in August, day one of it would make 91 or more inside one window - a breach, even though you were never anywhere near 90 days in one go.
Since Brexit this is the rule that governs UK passport holders visiting the EU: UK citizens travel visa-free, but on the standard third-country short-stay allowance. Border crossings are now logged biometrically under the EU's entry/exit system, so the arithmetic is enforced automatically - the days of a friendly shrug at passport control are over.
Which countries count
29 states as of 2026: 25 EU members plus Iceland, Liechtenstein, Norway and Switzerland; Bulgaria and Romania joined fully in January 2025. Ireland and Cyprus are not in Schengen - days there don't count against your 90. Days in the UK obviously don't either, but they may matter for something else entirely: your UK tax residence, which counts midnights, not days, under completely different rules.
What this calculator does and doesn't do
It does the official arithmetic: any part of a day inside the area counts, entry and exit days included, over the rolling 180-day window - the same method as the official EU short-stay calculator, with multi-trip planning on top: enter a whole future itinerary and see the exact date it would breach, plus the longest stay you could start today. It does not cover national long-stay visas, residence permits, bilateral visa-waiver quirks, or what to do about a past overstay - those are immigration questions for the country concerned, not arithmetic.
Schengen 90/180 questions, answered
How does the Schengen 90/180 rule actually work?
You may stay at most 90 days within ANY 180-day period across the whole Schengen area. It is a rolling window, not a fixed one: on every single day of a stay, count back 180 days and add up every day you were inside the area - that total must never exceed 90. Both your entry day and your exit day count as full days.
Do arrival and departure days count?
Yes, both. Any part of a day spent inside the Schengen area counts as a full day - so a Friday-to-Sunday city break uses 3 of your 90 days, and flying in at 23:50 still uses a day.
Does the counter reset when I leave?
No. Leaving does not reset anything - the window keeps rolling. A day only stops counting once it is more than 180 days in the past. That is why two long trips close together can breach the limit even though each one is under 90 days on its own.
Does the rule apply to UK passport holders?
Yes. Since Brexit, UK citizens are third-country nationals for Schengen purposes and get the standard visa-free short-stay allowance: 90 days in any 180-day period across the whole area. Time in one member state counts against the same allowance as time in any other.
Which countries count as Schengen?
29 states as of 2026: 25 EU members plus Iceland, Liechtenstein, Norway and Switzerland. Bulgaria and Romania are full members since January 2025. Ireland and Cyprus are EU members but NOT in Schengen - days there do not count against the 90. (Time in Ireland may still matter for UK tax residence, which is a separate calculation.)
Is the 90 days per country or for the whole area?
For the whole area combined. 40 days in Spain plus 40 days in France plus 15 days in Italy inside one 180-day window is 95 days - over the limit - even though no single country saw more than 40.
What is "the longest stay you could start today"?
The biggest number of consecutive days you could spend in the Schengen area starting today without the rolling window ever exceeding 90. The calculator simulates day by day: as old days fall out of the back of the window, new capacity opens up - so the answer is often more generous than "90 minus days used", but never more than 90.
When can I next do a trip of, say, 14 days?
Use the trip planner in the calculator: enter how many days you need and it returns the earliest start date on which a stay of that length fits without any 180-day window exceeding 90 days - taking your past trips and anything you have already planned into account. It simulates the whole stay day by day, so the answer accounts for days rolling out of the window mid-trip.
What happens if I overstay?
Overstaying can mean fines, an entry ban recorded in the Schengen Information System, and problems at future borders - and since the EES entry/exit system, crossings are logged biometrically, so overstays are detected automatically. This calculator only does the arithmetic; if you may have overstayed or need visa advice, speak to the embassy of the country concerned or an immigration adviser.
This tool performs the published short-stay day arithmetic on the dates you enter. It is not immigration, visa or legal advice, and it cannot verify your actual border crossings. For decisions that matter, cross-check the official EU calculator and the rules of the country you are visiting.
