Schengen DaysThe rolling 180-day window — and when your days come back
The most confusing part of the 90/180 rule is the word rolling. Your allowance is not reset by leaving; instead old days quietly return as they age out of the window. Here is how that works.
“Rolling” means the window moves
Every day, the 180-day window slides forward by one day. The newest day joins the front; the day that is now 181 days old drops off the back. So the set of days that “count” is different every single day.
Leaving does not reset anything
There is no fresh 90-day allowance just for crossing the border. A day you spent in the area keeps counting until it is more than 180 days in the past. Only then does it stop counting and free up one day for you.
When can I re-enter?
Your days return gradually, one per day, as each past day of presence exits the window. If you used up your 90 days, you get days back on the calendar dates exactly 180 days after each day you were present. A calculator shows the precise date your balance rises and how many days you regain.
Frequently asked questions
If I use all 90 days, do I wait 90 days or 180?
It depends how your days were spread. Days return 180 days after each was spent, so a single continuous 90-day stay frees up fully about 90 days after you leave; scattered stays return piecemeal.
Does a new calendar year reset my days?
No. The rule is a rolling 180-day window, not a yearly allowance, so January 1 changes nothing.
How do I know the exact date I can return?
Track your past days and the calculator projects the date your remaining days rise to what you need — no manual counting required.
