What This Calculator Does
The Microapp Schengen 90/180 Calculator tracks your days in the Schengen area against the rolling 180-day window — the rule that limits non-EU visitors to 90 days within any consecutive 180-day period. The 'rolling' aspect is what catches most travelers: it's not 90 days per calendar half-year; it's 90 days within the 180 days immediately preceding any given moment.
• Trip 1: Paris, March 1-15 (15 days)
• Trip 2: Rome, May 1-31 (31 days)
• Planning Trip 3: Amsterdam, August 1
As of August 1, looking back 180 days takes you to February 3.
• Trip 1 (March 1-15): all 15 days in window
• Trip 2 (May 1-31): all 31 days in window
• Total used: 46 days
• Days remaining: 44 days for August trip (you'd hit the limit ~September 13)
Note: Trip 1 starts rolling out of the window starting August 28 (180 days after March 1). The window keeps shifting.
The 90/180 Rule, Precisely
The official wording from EU regulations: a non-EU visitor "may stay in the Schengen area for up to 90 days in any 180-day period." The key word is "any." For any given day, you count back exactly 180 days and sum up your presence in that window. If the sum is over 90, you've overstayed.
Both endpoints count. If you enter on March 1 and leave on March 5, that's 5 days (March 1, 2, 3, 4, 5) — not 4. The stamp date matters, not the time of day. A 24-hour visit can use 2 days if it crosses midnight.
The window is rolling, not fixed. The window for "today" might include a 60-day stay. The window for "30 days from today" might include only 30 days of that stay because some of it has rolled out the back.
Which Countries Count
27 countries as of 2024 in the Schengen area:
| Region | Countries |
|---|---|
| EU + Schengen | Austria, Belgium, Bulgaria*, Croatia, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania*, Slovakia, Slovenia, Spain, Sweden |
| Non-EU + Schengen | Iceland, Norway, Switzerland, Liechtenstein |
| EU but NOT Schengen | Ireland, Cyprus |
| Non-EU and NOT Schengen | UK, Albania, Kosovo, Bosnia, Montenegro, Serbia, Turkey, Russia, Belarus, Ukraine, Moldova |
*Bulgaria and Romania joined Schengen for air/sea travel in March 2024; full land border integration is still in progress.
Practical implications: A trip from France (Schengen) to Ireland (EU non-Schengen) DOES count as leaving Schengen — your days reset until you re-enter. Trips between Schengen countries do NOT reset anything.
What Counts as a Day
Both entry and exit days are full days. Some examples:
- Land in Paris 11:30pm March 1, leave March 1 at midnight (impossible but illustrative): 1 day
- Land in Paris March 1, leave March 2: 2 days
- Land in Paris March 1, leave March 8: 8 days
- Transit through Frankfurt 6am-10am, then onto Croatia (non-Schengen until 2023): 1 day
- Cruise stops in Italy 8am-6pm, sleeps on the ship in international waters: 1 day (port visit counts)
The visa stamp determines the days. A delayed flight that lands at 1am the next day counts the next day's date, not yesterday's flight time.
Common Misconceptions
"I leave Schengen for 24 hours, my counter resets." No. The counter is rolling — leaving for 24 hours just means those 24 hours don't count against your total. You still have to wait for old days to roll out of the 180-day window naturally.
"I can spend 90 days in France, then 90 days in Spain." No. The 90/180 limit applies to the entire Schengen area as one unit, not per country.
"Tourist visa exemption gives me 90 days no matter what." No. The 90 days are within ANY rolling 180-day period. If you used 80 days in the past 6 months, you only get 10 more days right now.
"They don't really check." Border officers DO check, especially at land borders, especially when you've previously been near the limit, and especially with electronic stamping systems that all 27 Schengen countries now share.
Consequences of Overstaying
| Overstay length | Typical consequence |
|---|---|
| 1-3 days, accidental | Verbal warning at exit, sometimes a small fine |
| 1-2 weeks | Fine €100-€500, possible 1-year entry ban |
| 1+ months | Higher fines, deportation, 3-5 year entry ban likely |
| Multiple overstays / repeat offenders | 5+ year ban, possibly permanent for severe cases |
Consequences also vary by country — Germany and France are stricter; Italy and Greece sometimes more lenient. Don't bet on leniency; the calculator exists so you don't have to.
How to Stay Longer Legally
National long-stay visa (D-visa): Issued by a specific country (e.g., a French long-stay visa for digital nomads). Allows stays of 91-365 days but generally only in the issuing country.
Digital nomad visas: Several countries (Portugal, Spain, Estonia, Czechia, Greece) now offer specific visas for remote workers, typically 1-2 years renewable.
Residence permit: For those moving to a Schengen country for work, study, family reunion, or significant investment. Process varies by country, typically 3-12 months.
Citizenship: Through ancestry (especially Italian, Irish, Polish, German), naturalization (typically 5-10 years residency), or marriage. The longest path but the most complete.
Tips for Maximizing Your 90 Days
- Track exits as well as entries. Both count.
- Don't overstay even by a day "to be safe." Border systems are increasingly automated; what looks like leniency at one airport may be a recorded violation at the next.
- Schedule longer trips with breaks. 60 days in, 90 days out, 30 days back is sustainable.
- Save your boarding passes and visa stamps. Border officers have access to the SIS (Schengen Information System) but errors happen — having your own records helps if challenged.
- Re-enter cautiously after long stays. If you used 80 days in the past 6 months, that next entry needs to leave room within the rolling window.
Educational Tool — Not Legal Advice
This calculator implements the standard 90/180 rolling window math used by border officers. For an authoritative determination of your specific situation, use the official EU calculator at ec.europa.eu. For complex cases involving multiple visa types, residency applications, or potential overstays, consult an immigration lawyer in the country you'll be visiting.
