Schengen 90/180 Calculator: How Many Days You Have Left

How the rule works

  • 90 days inside the Schengen area in any 180 days.
  • The 180 days are counted backwards from whatever date you are asking about. Nothing resets on a fixed date; each day you spend returns 180 days later.
  • Your arrival day and your departure day each count as a whole day.

The mistake that gets people banned

Most calculators check your arrival date and stop there.

If you have 30 days left and book a 45-day trip, they wave you through. You land, and on day 31 you are an overstayer, inside the area, where it means a fine, a removal order, or an entry ban.

This one checks every day of the stay and gives you the date it stops being lawful.

If you want the rule itself

The arithmetic above is the whole of it, but the reasoning behind it is worth ten minutes: how the 90/180 count actually works, including why there is no reset date and why both travel days are whole days.

If the answer looks wrong

The rule is arithmetic, so it can be tested rather than asserted. The calculator runs an automated test suite on every change, and its output is checked by hand against the European Commission’s own short-stay calculator.

If you find a case where the two disagree, tell us. The Commission is right and we will fix it.
