DayWindow

How the Schengen 90/180 Rule Works

The short version: you can stay in the Schengen Area for up to 90 days in any rolling 180‑day period. “Rolling” means the 180‑day window moves forward one day at a time.

1) What “rolling 180 days” means

Pick a date (usually today). Look back 180 days from that date (including today). Add up every day you were in Schengen inside that window. If the total is 90 or less, you're within the rule.

2) Counting days

• Entry day counts
• Exit day counts
• Multiple trips add together
• Overlapping date ranges should be counted once (DayWindow merges overlaps)

3) A quick example

If your trips within the last 180 days total 65 days, then you have 25 days remaining (90 − 65 = 25).

4) How DayWindow calculates

1. DayWindow takes your trip periods (entry/exit).
2. It merges overlapping periods to avoid double‑counting.
3. It sums the days that fall inside the last 180 days (entry and exit included).
4. It shows Used, Remaining, and whether you are over 90.
5. If you are over 90, it finds the first future date when the rolling 180‑day total becomes 90 or less (“Next Entry”).
