When can I return to Schengen after 90 days?

If you stayed 90 days straight

Say you entered on January 1 and left on March 31 — a full, continuous 90-day stay. Your days start aging out of the rolling 180-day window one at a time, beginning with January 1, which becomes more than 180 days old on June 30. That is your first lawful day back. Only one day has freed up so far — but if you enter on June 30 and stay, January 2 ages out on July 1, January 3 on July 2, and so on: one old day leaves the window for every new day you add, so the count sits at exactly 90 and never goes over.

• First possible re-entry: 180 days after your original entry date — equivalently, 90 days after you left. On that date you have exactly 1 day of allowance.
• Any length of trip from that date: because the window rolls with you, entering on June 30 lets you stay a week, a month, or the full 90 days (to September 27) without breaking the limit. This is the "90 in, 90 out, 90 in" cycle — and it only works if the first stay was one continuous block.
• What you cannot do: come back before June 30 — not even for a weekend. Until then every one of your 90 days is still inside the window.

Check your own dates

Enter the entry and exit dates of your most recent stay and the widget gives the first day you may re-enter, the earliest start for a trip of the length you want, and the earliest start for a full 90-day stay — computed the way the EU's own calculator counts. For a single continuous stay all three land on the same day; they only spread out when your days were split across several trips.

If your days were spread across trips

Most travelers don't use their 90 days in one block, and that changes the arithmetic in your favor. Your oldest trips age out of the window first, so your allowance may already be rebuilding while your most recent days are still counting. Someone who did 30 days in autumn, 30 in winter, and 30 in spring gets their autumn days back much sooner than someone whose 90 days all happened in spring.

There is no shortcut formula for the scattered case — you have to count:

1. 1Pick a candidate return date.
2. 2Count back 180 days from it.
3. 3Add up every day you were inside Schengen in that range (entry and exit days both count).
4. 490 minus that total is what you may stay from that date — if it's zero, push the date later and repeat.

The Schengen 90/180 calculator automates exactly this: it tells you the earliest entry date for a trip of any length, given the stays you enter.

After 90 days in Spain (or Italy, France…) — same answer

People often ask this per country — "after 90 days in Spain, when can I return?" — but the allowance is shared across the whole Schengen Area, not per country. Days in Spain, Italy, France, Greece, and every other Schengen state pool into one 90-day count, and leaving Spain for Portugal or Germany doesn't stop the clock — only leaving Schengen entirely does. So the return-date arithmetic above applies identically wherever you spent your days, and returning "somewhere else in Europe" doesn't reset anything (unless it's a non-Schengen country like Ireland or the UK — or, pending its accession, Cyprus — which run separate allowances).

After 90 days in Spain, when can I return?

90 days after you left Spain if the stay was continuous — 180 days after the day you entered. If you split the time across trips, count the last 180 days as described above. Spain is a common case because many visitors spend a full winter there; note that Spanish border posts now read your EES record, so the "how long was I really there?" question is answered for you. Spain rules.

After 90 days in Italy, when can I return?

Identical arithmetic: first lawful day back is 180 days after your original entry, i.e. 90 days after leaving if you stayed the whole stretch. Days spent in Italy and days spent elsewhere in Schengen on the same trip are one count. Italy rules.

After 90 days in France, Portugal, or Greece

Same answer again — there is no French, Portuguese, or Greek version of the 90/180 rule, only the Schengen one. Country pages: France, Portugal, Greece.

How long after 90 days can I go back to Europe?

If "Europe" means the Schengen Area: 90 days after leaving (continuous case), or as soon as enough old days have aged out (scattered case). If it means Ireland or the UK, you can go straight away — they are outside Schengen and count separately.

Does waiting 90 days outside always work?

You may have read the rule of thumb "90 days in, 90 days out." It works only for the continuous case above: if you max out your 90 days in one stretch and then stay out for 90 days, your window is clean enough to re-enter — and, entering on that day, to stay for up to 90 more. If your stays were scattered, blindly waiting 90 days can be either too long (your oldest days already aged out) or, for planning a long stay, not long enough. When in doubt, count — or let the calculator do it.

Don't try to shave the dates

With the Entry/Exit System (EES) now recording border crossings biometrically, officers see your exact day count at the booth. Arriving a few days early relies on human leniency that the system has largely removed; overstays can mean fines, removal, and entry bans that follow you across all Schengen states. If you genuinely cannot leave in time (medical emergency, cancelled transport), apply for an extension inside the country rather than overstaying quietly.
