Schengen 90/180-day rule: how the rolling limit works
The limit is usually 90 days in any rolling 180-day period across the Schengen area as a whole. It is not 90 days in each country, and the calculation changes every day.
Unless the visa sticker authorises fewer days.
Count backwards from each day of the stay.
The allowance is combined across Schengen.
It is a rolling window, not a fixed block
The European Commission describes the rule as a maximum of 90 days within any 180-day period. For each day you plan to be in the Schengen area, count back 180 days and total the short-stay days inside that window.
Leaving for a few days does not reset the allowance. Older stay days fall outside the window one by one, so new days become available gradually.
Add every Schengen trip together
A stay in France, a weekend in Spain and a later trip to Switzerland all draw from the same allowance. Moving between Schengen countries does not create a new allocation.
The Schengen area currently has 29 countries. Cyprus and Ireland are not part of it and apply their own national entry rules.
Know when the calculator needs a different approach
If a short-stay visa shows an authorised stay shorter than 90 days, follow the visa sticker. The Commission also says not to enter periods covered by an EU residence permit or long-stay D visa into its short-stay calculator.
Residence, work, study and bilateral arrangements can create different rules. Use the calculator as a planning aid and the relevant immigration authority for the final decision.
Common mistakes
What to avoid
Using a fixed six-month block
The reference window moves forward daily; it does not reset on one calendar date.
Counting each country separately
Schengen short-stay days are normally pooled across the entire area.
Assuming a visa gives 90 days
A visa sticker can authorise a shorter stay.
Quick answers
Common questions
Does leaving Schengen reset the 90 days?
No. Days become available only as earlier stays move outside the rolling 180-day window.
Is the allowance 90 days in every Schengen country?
No. The usual short-stay limit is combined across all Schengen countries.
Do Cyprus and Ireland use this rule?
They are not part of the Schengen area and apply their own national entry and visa rules.
