How does the Schengen 90/180 day rule work?
You may stay in the Schengen area for a maximum of 90 days within any 180-day period. The 180-day window is rolling: on every single day of your stay, count backwards 180 days and total every day you were physically inside any Schengen country during that window. If that total ever exceeds 90, you are overstaying. Both your entry day and your exit day count as full days, and the counter is shared across all 29 Schengen countries — it does not reset when you cross from France to Italy.
Does the 90-day counter reset when I leave?
No.Leaving the Schengen area does not reset anything. Days you spent inside during the previous 180 days still count when you return. The only way days "come back" is when they age out of the rolling 180-day window — which is exactly what this calculator works out for you, including the next date you can legally re-enter.
What happens if I overstay in the Schengen area?
Overstaying — even by a few days — can result in fines, immediate deportation, and an entry ban of up to 5 years recorded in the Schengen Information System (SIS). With the EU's Entry/Exit System (EES) now logging every border crossing biometrically, overstays are detected automatically. If you need longer than 90 days, apply for a national (type D) visa such as a digital nomad visa or a retirement visa.
Which countries does this calculator cover?
All 29 Schengen members, including France, Germany, Spain, Italy, the Netherlands, Greece, Portugal, and the Nordic countries. It does not apply to Ireland or Cyprus (separate rules), and non-EU microstates differ. US, UK, Canadian, and Australian passport holders get the 90/180 allowance visa-free; many other nationalities need a short-stay Schengen visa first but follow the same day-count rule.
