The rule, explained
How the Schengen 90/180 Rule Works
Everything you need to know about the Schengen Area's short-stay rule, with worked examples.
The Basic Rule
Non-EU/EEA nationals can stay in the Schengen Area for a maximum of 90 days within any 180-day period. This applies to the entire Schengen Area as a whole — not per country. A week in France and a week in Germany both count toward the same 90-day limit.
The rule applies to visa-exempt travellers (e.g. US, UK, Canadian, Australian passport holders) and short-stay visa holders alike.
What "Rolling Window" Means
The 180-day period is not a fixed calendar period. It is a rolling window that moves forward every single day. On any given day, immigration looks back exactly 180 days and counts how many of those days you spent inside the Schengen Area. That total can never exceed 90.
Think of it as a spotlight that always shines backward 180 days from today. As each new day arrives, the oldest day drops off the back of the window. Days you spent in the Schengen Area eventually "fall off" and become available again — but only after a full 180 days have passed since those stays.
How Days Are Counted
- Both entry and exit days count as full days of presence. Arriving at 11:55 PM counts as a full day.
- Days are counted as calendar days, not 24-hour periods. Even a few minutes on a given day uses that entire day.
- Days spent outside the Schengen Area are not counted, even if you're in an EU country that is not part of Schengen (such as Ireland or Cyprus).
Worked Examples
Example 1: A Simple Trip
You fly to Spain on January 15 and leave on March 15.
Days used: January 15 to March 15 = 60 days (both dates count)
Days remaining: 90 − 60 = 30 days
Full reset on: September 11 (180 days after March 15, the last day of your stay)
On September 11, your January 15 stay has fully dropped off the 180-day window, and all 90 days are available again.
Example 2: Multiple Trips
You make two separate trips:
- Trip 1: France, January 10 → January 20 (11 days)
- Trip 2: Italy, March 5 → April 3 (30 days)
Total days used: 11 + 30 = 41 days
Days remaining: 90 − 41 = 49 days
Both trips count toward the same 90-day limit, even though they were in different countries and had a gap between them.
Example 3: Days "Falling Off"
You spent 80 days in Spain from January 1 → March 21. You leave and return on July 15.
On July 15, the 180-day window looks back to January 17. Days from January 1–16 have already dropped off the window.
Days still counting: January 17 → March 21 = 64 days
Days remaining: 90 − 64 = 26 days
As each day passes, more days from your earlier trip drop off. By September 17 (180 days after March 21), the entire stay has fallen off and all 90 days are available again.
Common Mistakes
"I can stay 90 days in a row, leave, then come right back"
The 90 days are cumulative, not consecutive. Leaving the Schengen Area for a few days does not reset your allowance. If you used 85 days and leave for a week, you still only have 5 days left — not a fresh 90. Previous days only "reset" when they fall outside the 180-day rolling window.
"The 90 days reset every calendar year / every 6 months"
The 180-day window is rolling, not tied to calendar dates. There is no reset on January 1st or every six months. The window moves forward one day at a time, and your allowance is recalculated daily.
"My entry day (or exit day) doesn't count"
Both entry and exit days count as full days of presence. Arriving at 11 PM still uses that entire calendar day. The European Commission's official calculator counts both dates as days of stay.
"Ireland and Cyprus are in the EU, so they count as Schengen"
Ireland has a permanent opt-out from the Schengen Area (it maintains its own Common Travel Area with the UK). Cyprus is legally obligated to join Schengen but has not yet done so. Time spent in Ireland or Cyprus does not count toward your 90-day Schengen allowance. The same applies to other non-Schengen EU/EEA territories.
"Three months is the same as 90 days"
Calendar months vary between 28 and 31 days. Three calendar months can be anywhere from 89 to 92 days. The rule specifies exactly 90 days — not "three months." Always count actual calendar days.
Consequences of Overstaying
Overstaying the 90/180 limit is a serious matter. Consequences vary by country but can include:
- Fines — typically ranging from several hundred to over a thousand euros
- Entry bans — usually 1 to 5 years, applied across the entire Schengen Area
- Deportation — immediate removal and a permanent record in the Schengen Information System (SIS)
- Future visa complications — overstay history can lead to visa refusals for years
With the Entry/Exit System (EES), every entry and exit is tracked biometrically. Even a single day of overstay is automatically flagged.
