Direct answer
The standard Schengen short-stay rule usually allows up to 90 days in any 180-day period. The rule is rolling, which means every day of your stay is assessed against the 180 days immediately before it.
What “90 days in any 180-day period” really means
The short-stay rule is not tied to a calendar year. You do not receive a clean reset every January or every six months on a fixed schedule.
It is rolling
Every day of your stay has its own 180-day look-back window.
Past trips stay in play
Older travel can still affect a new stay if those older days remain inside the active window.
The total must stay at 90 or below
If the total number of Schengen days inside that window exceeds 90, the stay becomes risky.
Do entry and exit days count?
Yes, both count
Official guidance treats the entry date as the first day of stay and the exit date as the last day of stay.
Simple examples
1 Mayentry and1 Mayexit =1day1 Mayentry and10 Mayexit =10days
A practical rolling-window example
Stay one
1 January to 10 January = 10 days.
Stay two
1 March to 20 March = 20 days.
Stay three
15 June to 30 June = 16 days.
Total in the relevant window
By the end of the June stay, that example would show 46 days if all those dates still fall inside the active 180-day look-back period.
Where travelers usually get it wrong
Assuming January resets everything
It does not. The rule is rolling, not calendar-year based.
Ignoring same-day travel
Entering and leaving on the same day still counts as one Schengen day.
Forgetting older trips
Past stays may still matter if they remain inside the relevant 180-day period.
Mixing short stays with long-stay permission
Residence permits and long-stay visas are not counted the same way as ordinary short-stay travel.
Need to test your own dates?
Use the Schengen 90/180 calculator when you want a practical allowance check instead of a theoretical explanation. If you travel more than once, compare it with the Schengen 90/180 Tracker app.
Rule logic, border systems, and tracking fit together
Travel more than once a year?
The website explains the rule clearly. The iPhone app is better when you want saved trips, repeated checks, and future trip planning.
- Save trips across repeat visits
- Check future plans without recounting
- Estimate safer exit and re-entry timing
90/180 rule FAQ
Does the Schengen 90/180 rule reset when I leave?
No. Leaving Schengen does not create an instant reset. The calculation keeps looking back over the previous 180 days for each day you want to stay.
Can I spend 90 days in the first half of the year and another 90 days right after?
Not automatically. A new stay depends on how many of your previous 180 days are still inside the rolling window on each travel day.
Do old trips stop mattering after 180 calendar days?
A past day stops affecting the calculation once it falls outside the relevant 180-day look-back window.
What is a rolling 180-day window?
It is the 180-day period immediately before a specific day of stay. The window moves forward one day at a time instead of staying fixed to a calendar period.
Do travel days count?
Yes. The entry day counts as a day of stay and the exit day counts as a day of stay.
Do all Schengen countries share the same short-stay limit?
For the standard short-stay rule, the allowance is shared across the Schengen area rather than reset separately for each Schengen country.
Is the rule different for visa-free travelers and visa holders?
The 90/180 short-stay framework is the same basic rule, but a visa can include its own conditions and does not replace the need to respect the overall short-stay limit.
