Methodology and Limitations

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 tool does not know whether a trip record is incomplete or entered incorrectly.
  • It does not determine visa class, legal status or residence rights.
  • It does not account for every national exception or individualized legal scenario.
