When can I go back to Schengen?
You've used some or all of your 90 days and left. Now you want to know when you can come back, and for how long. Here's how to work it out.
The short answer
You can go back on any date where the 180 days ending that date, counting the arrival day itself, hold 90 or fewer days in the Schengen area. Days come back one at a time, each exactly 180 days after the day you spent. Nothing resets when you leave. If you've used all 90 in one continuous stay, your first day back is 180 days after the first day of that stay.
Being allowed back is only half the question. The other half is how long you can stay once you're in, because every day of the new stay is checked against its own 180-day window.
Your "next day back"
Each day you spend in the Schengen area stays in your count until it drops out of the window, 180 days after the day itself. So the first day of your oldest counted trip is the next day that comes back to you. That's your "next day back". After it, the rest of your days come back one at a time, in the order you spent them.
If you have days left today, you don't need to wait for anything: you can enter now, and the question is just how long you can stay. If you have no days left, the next day back is the earliest date you could arrive. The full counting method is in how Schengen days are counted.
After a full 90 days
- You stay in Spain from 10 April to 8 July 2026. That's 90 days, and on 8 July you've used all of them.
- 10 April leaves your window 180 days later, on 7 October 2026. Until then, every day in the window is still counted.
- A two-week trip to France starting 20 July 2026 would put you over on its first day: 20 July would be day 91.
- On 7 October 2026, the window (11 April to 7 October) holds 89 of the Spain days. Arriving that day makes it 90.
- From then on, each day you stay is matched by one Spain day leaving the window.
Your earliest return is 7 October 2026. That's the same whether you come back for two weeks or for the full 90 days, and from that date you could stay until 4 January 2027. Staying on to 5 January 2027 would be day 91.
After part of your 90 days
When you've used some of your days, the question becomes: if I arrive on this date, how long can I stay? It depends on how many days you have left on arrival and on which old days drop out while you're there.
- You spent 1 June to 30 July 2026 in Portugal: 60 days.
- You'd like to go back for 45 days, from 15 September to 29 October 2026.
- On 15 September you have 30 days left. None of the Portugal days leaves the window until 28 November, so nothing comes back during this trip.
- 15 October would be day 91, and by 29 October you'd be 15 days over.
Arriving on 15 September, the longest stay that fits is 30 days, leaving by 14 October 2026. For the full 45 days, the earliest safe start is 29 October 2026: you'd reach 90 on 27 November, and from 28 November each new day is matched by a Portugal day leaving the window.
How to check your own dates
- Write down every Schengen trip in the last 180 days, and any you've already booked.
- Pick the date you'd like to arrive and count your days used in the 180 days ending that day, including that day.
- If that's 90 or less, walk forward one day at a time: add a day for each day you stay, and take one off for each old day that's now more than 179 days back.
- The last day before the count would reach 91 is the last day you can stay.
That's tedious by hand, which is what our free Schengen calculator is for. It shows your next day back and how long you could stay if you arrived today. Add a planned trip and it tells you whether it fits, the longest stay that fits from its start date, and the earliest date a trip of that length would fit.
