The Schengen 90/180 rule says that most non-EU visitors can stay in the Schengen Area for up to 90 days in any 180-day period. The 180 days are not a fixed half-year. They form a rolling window that moves forward one day at a time, and on every day of your stay you must not have spent more than 90 days in the area during the 180 days that end on that date.
That rolling window is why people make mistakes. Leaving for a week does not reset anything, and simple subtraction often gives the wrong answer in both directions. This guide explains the rule, then works through dated examples you can check with the European Commission’s official calculator.
Key takeaways
- The rule allows a maximum of 90 days of presence in any rolling 180-day period across all 29 Schengen countries combined.
- The day you enter and the day you leave both count as full days in the Schengen Area.
- Leaving the area does not reset the count. Old days only stop counting when they fall outside the 180-day window.
- Time on a national long-stay visa or residence permit is not counted toward the 90 days.
- Since 10 April 2026, the EU’s Entry/Exit System records entries and exits electronically and flags overstays automatically.
What the Schengen 90/180 rule says
The rule comes from Article 6 of the Schengen Borders Code, the EU regulation on border checks. It applies to non-EU nationals on short stays, which covers visa-exempt visitors, such as citizens of the US, UK, Canada and Australia, and holders of Schengen short-stay visas.
The limit applies to the Schengen Area as one zone. According to the European Commission, the area has 29 countries: 25 EU member states plus Iceland, Liechtenstein, Norway and Switzerland. Bulgaria and Romania became full members on 1 January 2025. Cyprus and Ireland are EU members but are not part of the Schengen Area, so days there do not count toward the 90.
Article 6 also settles the question of partial days. The date of entry counts as the first day of the stay, and the date of exit counts as the last day. A trip from Friday to Sunday uses three days, even if you landed late on Friday and left early on Sunday.
How the rolling 180-day window works
To check whether a day is allowed, take that date and look back over the 180 days that end on it, which means that date plus the 179 days before it. Count every day you were in the Schengen Area in that window. If the total is 90 or fewer, you are within the rule on that date.
The window moves forward each day. Each morning, one old date drops out of the back of the window and one new date enters at the front. If you were in the area on the date that dropped out, you gain a day of room. If you are in the area on the new date, you use a day.
The European Commission’s short-stay calculator applies this method. You enter past trips and either a date to check or a planned entry date, and it tells you how long you can stay.
Worked examples of the 90/180 rule
The examples below use 2026 dates. They count both entry and exit days, as the Schengen Borders Code requires.
Example 1: one long stay
Maya, a US citizen, enters France on 1 March 2026 and stays in the Schengen Area until 29 May 2026. That is exactly 90 days, so her last legal day is 29 May.
When can she come back? Each of her 90 days must leave the window before she can use it again. If she stays out from 30 May until 27 August, she can re-enter on 28 August. From that date, one old day drops out of the window for every new day she spends in the area, so she can stay up to another 90 days, until 25 November 2026. For a single continuous stay, the pattern is 90 days in, then 90 days out.
Example 2: several shorter trips
James, a British citizen, makes three trips in 2026:
| Trip | Dates | Days |
|---|---|---|
| Trip 1 | 10 to 19 January | 10 |
| Trip 2 | 1 to 30 March | 30 |
| Trip 3 | 15 May to 13 June | 30 |
| Total | 70 |
He plans to enter again on 1 July. Simple subtraction says he has 20 days left (90 minus 70). The real answer is 30 days, with a last legal day of 30 July.
The reason is the rolling window. While he is in the area in July, his January days drop out of the back of the window, giving him 10 extra days. On 30 July, the window starts on 1 February, so it holds the 60 days from March, May and June plus 30 days in July, which is exactly 90. On 31 July he would reach 91.
Example 3: the reset myth
Lena, an Australian citizen, enters Italy on 1 April 2026 and stays until 30 May, which is 60 days. She spends 1 to 14 June in London, then returns to the Schengen Area on 15 June, expecting a fresh 90 days.
She does not get them. Her April and May days are still inside the window. She can stay 30 days, until 14 July. If she stays beyond that, she overstays, even though she left the area in between.
Example 4: weekend trips add up
Sam lives in London and takes a Friday-to-Sunday trip to a Schengen country every other weekend. Each trip counts as three days because the entry and exit days both count. Over 180 days that is roughly 13 trips and about 39 days, which is within the limit. Add a two-week holiday and a few work trips, and the total can climb toward 90 faster than expected.
Days that do not count toward the 90
Some time in Europe is outside the 90/180 rule:
- Long-stay visas and residence permits. Periods of stay under a national long-stay (D) visa or a residence permit are not counted. The Commission’s calculator tells users not to enter those periods.
- Non-Schengen countries. Days in Cyprus, Ireland, the United Kingdom and non-Schengen countries such as Albania, Serbia, Montenegro, North Macedonia and Bosnia and Herzegovina do not count, because they are outside the area. Each of those countries has its own entry rules.
- Bilateral agreements. A few nationalities can rely on older bilateral visa-waiver agreements with individual Schengen states. These agreements are narrow and vary by country, so people who plan to use one usually confirm the terms with that country’s embassy first.
National long-stay routes are the main legal way to stay longer than 90 days. Our list of digital nomad visas in 2026 covers the European options, including Spain, Portugal, Croatia and Hungary’s White Card.
How the Entry/Exit System enforces the rule
Until 2026, border guards checked passport stamps by hand to work out a traveler’s days. According to the European Commission, the Entry/Exit System (EES) began operating on 12 October 2025 and became fully operational on 10 April 2026, when it replaced passport stamping.
The EES records each entry and exit electronically, together with your passport details, facial image and fingerprints. It calculates your remaining days and flags overstays automatically. That makes a counting error much easier for a border guard to see. Our guide to EES and ETIAS explains the system in more detail.
What happens if you overstay
The penalties for overstaying are set by each Schengen country, not by one EU rule. They can include fines, removal and entry bans that apply across the Schengen Area. Under the EES, records of travelers who overstay are kept for longer than records of travelers who leave on time, and they are shared with border, visa and immigration authorities.
An overstay can also cause trouble later, for example when you apply for a visa, a residence permit or an ETIAS travel authorization. If a flight cancellation, illness or other serious event forces you to stay longer, it helps to document it and contact the local immigration authority before your days run out.
Planning around the 90/180 rule
People who spend a lot of time in Europe tend to use a few simple habits:
- Keep a running log. Record every entry and exit date and check it against the official calculator before each trip. Our guide on how to track days for tax residency covers logging methods that work for both visa and tax purposes.
- Check the future, not only today. A plan can be legal on the day you enter and illegal three weeks later. Use the calculator’s planning mode for the full trip.
- Treat exits as time-outs, not resets. Days outside the area only help when they let old days fall out of the window.
- Know the alternatives. If you want to stay longer, a national visa or residence permit is the lawful route. Our guide to visa runs explains why border hopping does not work in Schengen.
Frequently asked questions
Does the day I arrive in Schengen count as a full day?
Yes. Under Article 6 of the Schengen Borders Code, the date of entry is the first day of stay and the date of exit is the last day, whatever time you cross.
Does leaving the Schengen Area reset the 90 days?
No. The rule looks at the 180 days before each date, so days you spent in the area keep counting until they fall outside that window. A trip to the UK or Albania only helps by letting time pass.
Do days in Cyprus or Ireland count toward the 90 days?
No. Cyprus and Ireland are EU members, but neither is part of the Schengen Area, so days there do not count toward the Schengen limit. Each country applies its own entry rules.
Does time on a residence permit count toward the 90 days?
No. Periods of stay under a residence permit or a national long-stay visa are not counted. When you travel to other Schengen countries as a short-stay visitor, the 90/180 rule applies to that travel.
Is there an official Schengen 90/180 calculator?
Yes. The European Commission publishes a free short-stay calculator on its Migration and Home Affairs website. It can check a past stay or plan a future one.
