Short-stay rule / 90 days in any 180

How many Schengen days do you have left, and when can you come back?

Add your trips. The counter looks back 180 days from any date you pick, counts the entry and exit day, and tells you what is left and when more days free up.

1. Your trips in the Schengen area

The trips below are an example. Replace them with yours. Nothing leaves your browser.

Count as of this date

2. Where you stand

Each square is one of your 90 allowed days in the window. Dark = used, red = over the limit.

3. Your rolling total, 6 months back and 6 months ahead

4. Plan the next trip

Entry date

Days you want to stay

The second box searches forward from the entry date for the first day you could start a stay of that length without ever passing 90.

5. Day by day

How it counts and sources

Limit: "a maximum of 90 days within any 180-day period"; you "count back 180 days from each day of your stay". European Commission, short-stay calculator.
"The day of entry counts as the first day in the Schengen area, and the day of departure counts as the last." The 180-day window is rolling. Swiss State Secretariat for Migration. Its worked example (1 March to 29 May uses 90 days, re-entry possible 28 August) is reproduced by this page.
The area has 29 countries; Cyprus does not yet apply it fully and Ireland is outside. European Commission, Schengen area.

One note: this applies to short stays without a residence permit or long-stay visa. Border officers decide, so keep it as a planning aid and check the official calculator before a tight trip.
