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.
