What is the Schengen 90/180 rule?

The Schengen 90/180 rule limits most short-stay visitors to 90 days inside the Schengen Area in any rolling 180-day period — the window looks backward from each day you are present, not two fixed halves of the calendar year.Keep reading: Schengen 90/180 Calculator: Track Your Rolling Allowance

Arrival and departure days usually count as full days. Leaving for a weekend does not ‘reset’ your allowance unless enough prior days have aged out of the look-back. Ireland and some other European states sit outside Schengen, so nights there do not consume the same clock. territory lists for your itinerary.

How does the rolling 180-day window work?

On any day you are in Schengen, sum the days you already spent in the Area during the previous 180 days; if that sum would exceed 90, you are over the short-stay limit and need to wait until older days fall out of the window.

Long-stay national visas and residence permits follow different rules. Do not mix a D-visa clock with visa-free short-stay maths in one spreadsheet. For worked tables and edge cases, use the full guide Schengen 90/180 rule explained and the Schengen calculator.

What is a simple 90/180 example?

If you spent 40 days in Spain in March and return on 1 August for 55 days, both blocks can still sit inside one 180-day look-back — 95 days would breach the 90-day cap even though each trip felt ‘under three months’.

That is why ‘visa runs’ to nearby non-Schengen cities often fail as a strategy: the clock cares about presence days inside the Area, not whether you took a selfie in another country for 48 hours. See what is a visa run and what happens if you overstay Schengen.

How do you count your 90/180 days correctly?

Count every day — entry and exit days included — spent in any Schengen country over the rolling 180 days before today; the total must never exceed 90, and the calculation window moves daily, which is exactly what trips up long-stay travellers.

The rule is a rolling window, not a calendar half-year. On any given day, look back 180 days and sum every day you were inside the Schengen area — partial days count, airport transit airside usually does not. The classic mistake is treating it as “90 days per visit” and re-entering after a weekend outside the zone; the window follows you, and days only fall off one by one as they age past 180.

Manual counting errors are common enough that border guards see them weekly, so use a calculator: enter your past and planned stays and check the remaining allowance before booking, not at the gate. Build a small safety margin — a cancelled flight on your planned exit day can tip you into overstay through no fault of your own, and “the airline cancelled” is a weak defence.

Overstays are recorded in the shared entry database and consequences scale from fines to multi-year entry bans, with enforcement tightening as the biometric Entry/Exit System automates the counting. Non-Schengen respites like the UK, Ireland, Croatia’s neighbours or Morocco let your clock recover.
