Who Maintains Schengen Calculator
Schengen Calculator is a free tool maintained by the team behind NomadSync, a travel-tracking app for long-term and frequent travellers. We built this calculator because the 90/180 rule is widely misunderstood, and a single miscount at the border can mean fines or an entry ban.
The site is intentionally simple: a fast, free calculator and clear, plain-English guides to the rules that govern short stays in the Schengen Area. There is no signup and no account required to use the calculator.
Important
General Information, Not Legal Advice
Everything on this site is general information intended to help you understand and plan around the 90/180 rule. It is not legal or immigration advice, and it does not create any professional relationship.
Border rules can change and can be applied differently by individual member states. For any decision that affects your travel, always confirm with official government sources or a qualified immigration professional. Border authorities have the final say on your day count and your right to enter.
The method
How the 90/180 Calculation Works
Our calculator estimates days used in one rolling 180-day window from the trip dates you enter. Here is how it works:
- 1For any reference date, it looks back exactly 180 days and counts how many of those days you spent inside the Schengen Area.
- 2The usual short-stay limit is 90 days in any 180-day window. The window moves forward one day at a time — there is no annual or biannual reset.
- 3Both the entry day and the exit day of each trip are counted as full days of presence.
- 4Time in every member state counts toward the same single 90-day allowance — it is area-wide, not per country.
- 5Older stays only free up days once they fall outside the 180-day window, which is why we also show your next full-reset date.
A result for one date does not check every day of a future stay. Check your plan with the European Commission short-stay calculator. For worked examples, see how the 90/180 rule works.
