The Schengen 90/180 rule, explained correctly
Last updated: 2026-07-10
Non-EU visitors may stay in the Schengen area for at most 90 days in any 180-day period. Both numbers hide traps: the window is rolling, and entry and exit days count in full.
A rolling window, not a reset
For every day of your stay, look back at the 180-day period ending on that day and count your days of presence; the total must stay at or under 90 (Art. 6(1)(b) of the Schengen Borders Code). Leaving for a weekend does not reset anything: each used day only stops counting 180 days after you used it. One consequence the Commission states explicitly: an uninterrupted absence of 90 days always allows a fresh 90-day stay.
Entry and exit days both count
The date of entry is your first day of stay and the date of exit is your last. Landing at 23:00 still spends a full day. A Friday-to-Sunday weekend is three days, not two. Days spent under a residence permit or a national long-stay (D) visa do not count toward the 90.
The '90 in, 90 out' myth
Because the window rolls daily, schemes like 'stay 90, leave for a month, come back' fail: on re-entry, most of your 90 days are still inside the window. The only reliable method is counting the actual window for the actual dates, which is what the calculator on this site does, using the same method as the Commission's official tool, validated against every example in its manual.
