This page explains how the educational calculator approaches date counting and where its limitations begin.
Counting logic
The calculator counts travel days inclusively, meaning both entry and exit dates count. It analyzes the rolling 180-day window using the dates entered by the user.
Important limitations
The calculator has been carefully tested before publication, but irregularities cannot be completely excluded. We make reasonable efforts to keep the calculation logic accurate and stable, but results remain educational estimates only.
- The tool does not know whether a trip record is incomplete or entered incorrectly.
- It does not determine visa class, visa sticker validity, legal status or residence rights.
- It does not account for every national exception, bilateral visa waiver arrangement or individualized legal scenario.
- Printed, PDF and CSV outputs are only snapshots of the entered data at the time they were generated.
Browser-based operation
The calculator runs in the visitor’s web browser using JavaScript. Trip entries are stored locally in this browser and are not sent to our server by the calculator. Website features such as consent management, analytics, security or advertising may use cookies or similar technologies where enabled and permitted by user choices.
Why this page is useful
Read this page if you want to understand how dates are counted, why a rolling 180-day window can change day by day, and why the result should still be checked independently.
