How this calculator works

The calculator creates a rolling window ending on the reference date, then counts inclusive overlap days for each entered Schengen stay inside that window.
Window start = reference date - window days + 1. Used days = inclusive stay days overlapping the window. Remaining days = allowed days - used days.

Inputs explained

Reference date

The date on which you want to estimate remaining Schengen days.

Entry and exit dates

Dates for Schengen stays. This model counts both the entry date and exit date when they overlap the rolling window.

Allowed days and window length

Editable thresholds, defaulting to 90 allowed days in a 180-day lookback window.

Understanding your results

The primary result is estimated remaining days in the entered window. A negative value means the entered stays exceed the entered allowance.

Example scenarios

Recent travel example

If 42 overlapping days are found in a 180-day window and the allowance is 90 days, the estimate shows 48 remaining days.
