Schengen 90/180 Day Calculator

How it works

days used on date D = number of days present in [D − 179, D] · allowed if ≤ 90 on every day of the stay · remaining = 90 − used · longest stay from D found by simulating day by day

The Schengen short-stay rule is not a quota per half-year but a rolling one: on any given day, look back 180 days and count the days you were in the area — it must never exceed 90. Because the window moves with you, days spent long ago fall out as new ones are added, which is why a stay can sometimes run longer than today's remaining balance and why simply adding up trips per calendar year gives the wrong answer. Both the entry and the exit day count as full days, and every day of a planned stay has to pass the test, not just the first. The calculator rebuilds the calendar from your trips and evaluates the window on the day you choose, then walks forward to find the last day you may stay.

Worked example

With stays of 2–20 March (19 days), 10 May–12 June (34 days) and 1–25 August (25 days), checking 1 September 2026 shows 74 days used in the window 6 March–1 September (15 of the March days are still inside it), leaving 16. Yet entering on 1 September you could stay 31 days, until 1 October, because the remaining March days drop out of the window during the stay; the May days only start to drop out from 6 November, so a longer stay would have to wait until then.
