How the schengen 90/180 calculator works
Visitors from visa-exempt countries, including the US, UK, Canada and Australia, may stay in the Schengen area for up to 90 days in any 180-day period. The window rolls: on any given day, you look back 180 days and count every day you were in a Schengen country.
Both the entry and exit days count as full days. This calculator gives a conservative check by assuming all of your past days are still inside the window for your whole trip. If some of those days fall out of the window during your trip, you may have more time; the European Commission's official short-stay calculator checks exact dates. The EU's Entry/Exit System (EES) now records entries and exits electronically, so overstays are easy to detect, and ETIAS pre-travel authorization is due to start for visa-exempt visitors.
Worked example
You spent 40 days in France and Italy in the past 180 days and plan a 30-day trip to Spain. That totals 70 of 90 days, so the trip is allowed, and you would have 20 days left. The longest trip you could start now is 50 days.
Frequently asked questions
How does the 90/180 rule work?
On any day in the Schengen area, the total days you have spent there in the previous 180 days, including that day, must not exceed 90.
Do entry and exit days count?
Yes, both count as days in the Schengen area.
Does the count reset after 180 days?
No. The window rolls daily, so each old day drops off exactly 180 days later.
What happens if I overstay?
Penalties can include fines, deportation and entry bans, and overstays are recorded by the Entry/Exit System.
