Schengen 90/180 Rule Explained (With Worked Examples)

If you are spending more than a few weeks in Europe, the Schengen 90/180 rule sets your limit: up to 90 days in any 180-day period across 29 countries, counted as one area. The 180 days are not a fixed block. The window rolls forward every day, so the days you have left change daily. Here is how to count them day by day, when you can come back, and what EU border records now track.

What the Schengen 90/180 rule says

The rule covers short-stay visitors who are not citizens of an EU country, Iceland, Liechtenstein, Norway or Switzerland. US passport holders are on the EU’s visa-exempt list for stays of no more than 90 days in any 180-day period, and travelers who need a short-stay visa count their days the same way.

The 90 caps your days inside the area; the 180 is the window you look back over. Every entry inside that window feeds one shared count, unlike a per-entry limit such as the 90-day ESTA limit, where US law caps each Visa Waiver admission at 90 days.

Article 6 also sets the passport condition: it must be valid for at least 3 months after the day you plan to leave the Schengen area, and issued within the previous 10 years. ETIAS, the EU’s planned travel authorization for visa-exempt visitors, is not in operation as of October 2026 and takes no applications yet.

Which countries count toward your 90 days

Every day in any of the 29 Schengen countries comes off the same 90. They are 25 EU members (Austria, Belgium, Bulgaria, Croatia, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain and Sweden) plus Iceland, Liechtenstein, Norway and Switzerland. Bulgaria and Romania were the last to join, on 1 Jan 2025.

If you hold a Schengen visa, the same 90/180 count applies, and the visa sticker may print a shorter authorized stay that limits you first. That visa also opens some borders outside the area, Montenegro among them for up to 30 days, and days spent there stay off your Schengen count.

Day or place	Counts toward the 90?	Why
The day you arrive, even at 23:30	Yes, as a full day	The entry date is the first day of stay
The day you leave, even at 06:00	Yes, as a full day	The exit date is the last day of stay
A day trip in and out	Yes, 1 day	Entry and exit fall on the same date
Days in Bulgaria or Romania	Yes, since 1 Jan 2025	Both joined the Schengen area that day
Days in Ireland or Cyprus	No	EU members outside the Schengen area
Days in the UK, Albania or Montenegro	No	Outside the Schengen area
Days on a national long-stay visa or residence permit	No	Excluded by Art. 6(2) of the Borders Code
Days spent 180 or more days before the day being checked	No	They have rolled out of the window

How to count 90 days in any 180-day period

The method the European Commission gives is short: count back 180 days from each day of your stay, and the days you spent in Schengen in that stretch must not exceed 90. In practice the last day of each stay is the one to test: during a stay the total can only rise or hold steady, so if your planned last day passes, every day before it passes too.

Count calendar dates, not hours: 3 to 12 June is 10 days, not 9, however late you land or early you leave. Think in days, never months: 1 Jun to 31 Aug is 92 days, 2 over the limit.

Your passport will not help with the count. Since 10 Apr 2026 the EU’s Entry/Exit System (EES) has replaced entry and exit stamps for short-stay visitors at Schengen borders, so keep your own list of dates from boarding passes and bookings.

Maya, a sample traveler on a US passport, spends 1 Feb to 2 Mar 2026 in Lisbon (30 days) and 15 Apr to 14 May 2026 in Rome (30 days), then lands in Athens on 1 Jul 2026. Each row checks one day: the 180-day window ending that day, and her Schengen days inside it.

Day checked	Window starts	Lisbon days	Rome days	Athens days	Total
1 Jul	3 Jan	30	30	1	61
30 Jul	1 Feb	30	30	30	90
31 Jul	2 Feb	29	30	31	90
15 Aug	17 Feb	14	30	46	90
29 Aug	3 Mar	0	30	60	90
30 Aug	4 Mar	0	30	61	91, over

She reaches 90 on 30 Jul but is not over: from 31 Jul, one Lisbon day drops out for every new Athens day, so the total holds at 90. Her last legal day is 29 Aug, day 60 of her Athens stay. Had she landed on 1 Jun instead, every earlier day would still be in the window, and her last legal day would be 30 Jun.

When you can come back after 90 days

There is no reset. Leaving Schengen stops new days from being added, but it does not erase old ones. Each day leaves the count exactly 180 days after you spent it, so a day spent on 1 Jan 2026 stops counting on 30 Jun 2026.

That is why a short exit and re-entry, the move behind visa runs in countries that grant a new stay at each entry, gains nothing in Schengen. A weekend in London or Dublin puts no days back; only time does.

For a single 90-day block, the earliest return is day 181 counted from the block’s first day. After several shorter trips you can come back sooner. Your free days are then counted on each day of the stay as the window moves, and older days rolling out are what let Maya’s Athens stay above run to 60 days.

A sample traveler on a US passport stays in Schengen every day from 1 Jan to 31 Mar 2026, exactly 90 days, then leaves.

Arrival or check date	Window starts	Days from Jan to Mar	Days on the new trip	Total
Arrive 29 Jun	1 Jan	90	1	91, refused
Arrive 30 Jun	2 Jan	89	1	90
31 Jul	2 Feb	58	32	90
31 Aug	5 Mar	27	63	90
27 Sep	1 Apr	0	90	90
28 Sep	2 Apr	0	91	91, over

On 29 Jun the window still holds all 90 old days, and a traveler who has already used 90 days in 180 is refused entry at the border. From 30 Jun, one old day drops out for each new day added, so the second stay can run to 27 Sep 2026: another 90 days.

Checking your days with a Schengen calculator

The European Commission’s short-stay calculator does the counting for you: Check mode tests stays you have already made, and Planning mode gives the longest stay for a future entry date. If your short-stay visa sticker shows fewer than 90 days, the calculator is not meant for your case.

The EU’s EES online tool answers OK or NOT OK and shows the days you have left. It does not count time from any stay that began before 10 Apr 2026, and an OK is not an entry decision: the border officer still makes that call.

Check a trip against the 90/180 rule before you book

1. Collect the entry and exit date of every Schengen trip in the 180 days before your planned last day, from boarding passes, booking emails and train tickets.
2. Open the short-stay calculator and pick Planning mode for a future trip, or Check mode for a stay you are already on.
3. Enter each past stay in dd/mm/yy format, counting the arrival and departure days in full, and leave out days on a long-stay visa or residence permit.
4. Enter your planned arrival date and note how many days it allows, which gives your last day.
5. Book your flight out on or before that date, with a spare day in case a connection slips.
6. Cross-check your remaining days with the EES online tool.

What happens if you stay more than 90 days

Inside the area, the EES detects overstayers automatically from the entries and exits it records. At the border, a traveler who has already used 90 days in the window is refused entry, and that refusal goes into the EES as well.

The penalties for overstaying in Schengen are set by the country you are in, and can include removal, fines, detention and refused entry on later trips. Return decisions and entry bans go into the Schengen Information System, and an entry ban should not in principle exceed 5 years.

Staying in Europe longer than 90 days legally

Days on a national long-stay visa (a D visa) or a residence permit do not count toward the 90, so a longer stay means applying to one Schengen country for one of those, under that country’s own rules.

For a visa-free visitor, extending a tourist stay past 90 days inside Schengen is possible only in narrow cases. The Schengen convention keeps each country’s right to extend a stay beyond 90 days, but only in exceptional circumstances or under a bilateral agreement concluded before the convention took effect. Ask that country’s embassy which of those older agreements still apply, and to which passports, before you count on extra days.
