Short answer: A Schengen calculator counts how many days you have spent in the Schengen Area in any rolling 180-day period, so you can check you stay within the limit of 90 days. To use one, enter the dates of your past entries and exits and the dates of your planned trip. The tool looks back 180 days from each day of your trip and tells you whether you would go over 90 days. The European Commission offers an official Schengen calculator online, and you can also count by hand using the steps below.

What is the Schengen 90/180 rule?
The Schengen Area is a group of European countries that share common border rules. Visitors on short stays can spend up to 90 days in the whole area within any 180-day period. The 180 days are not fixed calendar blocks. Instead, they move: on any given day, you look back at the previous 180 days and count how many you spent inside the area. If the total, including today, is 90 or less, you are within the rule.
This applies whether you need a Schengen visa or travel visa-free, for example as a British, American or Canadian citizen. Days spent in any member country count together.
What is a Schengen calculator?
A Schengen calculator is a tool that does this rolling count for you. You enter your trips, and it tells you how many days you have used and how many you have left on a chosen date. The official Schengen calculator from the European Commission is free and has a “check” mode for planned trips and a “control” mode for a date in the past.
How do you count your days, step by step?
If you prefer to check by hand, or want to understand what the tool is doing, follow these six easy steps:
- List every trip to the Schengen Area in the last six months, with entry and exit dates.
- Pick the last day of your planned trip.
- Count back 180 days from that day, including it.
- Add up the days you spent in the area during that window. Entry and exit days count as full days.
- Add your planned days that fall inside the window.
- Check the total. If it is 90 or less on every day of the trip, you are within the rule. If not, shorten the trip or move the dates.
Checking only the last day is often enough, but on longer trips it is safest to check several days, because the window moves each day.
Worked examples
| Example | Past trips (last 180 days) | Planned trip | Result |
|---|---|---|---|
| A | None | 30 days in Italy | 30 of 90 used: fine |
| B | 60 days in Spain, ending 2 months ago | 30 days in France | 90 of 90 used: just within the limit |
| C | 75 days in Germany, ending 1 month ago | 20 days in Greece | 95 used: too many, shorten by 5 days |
| D | 89 days, ending 6 months ago | 60 days in Portugal | Older days have dropped out: likely fine, confirm with the tool |
Example D shows why the rolling window matters. Days from more than 180 days ago no longer count, so your allowance “refills” over time.
Do days in the UK, Ireland or Cyprus count?
No. The UK and Ireland are not in the Schengen Area, so time there does not count. Cyprus is in the EU but not yet a full Schengen member, so its days are counted separately. Bulgaria and Romania joined the Schengen Area fully in 2025, so days there now count. Always check the latest list of member countries before you travel, because membership can change.
Does the 90/180 rule apply to visa holders too?
Yes. A Schengen visa shows the number of days allowed and the validity dates, but the 90/180 rule still applies. A multiple-entry visa valid for five years does not mean you can stay for long periods; you must still stay within 90 days in any 180. Use a Schengen calculator to plan each trip within your visa’s validity.
What is the Entry/Exit System and why does it matter?
The Entry/Exit System (EES) is the EU’s digital border system. It records your name, passport details, fingerprints, facial image and the dates you enter and leave. It started in October 2025 and was introduced in phases at border crossings. Because the system counts your days automatically, overstays are now much easier for border officers to see. That makes checking your dates with a Schengen calculator more important than ever.
A separate travel authorisation for visa-free visitors, called ETIAS, is planned after the EES. Check the official EU website for the latest start date before you travel.
What happens if you overstay?
Overstaying even by a few days can lead to:
- a fine
- removal from the country
- an entry ban for a period of time
- problems with future visa applications to Schengen and other countries
If you are delayed for a reason beyond your control, such as illness or a cancelled flight, contact the local immigration authorities before your allowed time ends and keep proof of the problem.
Can you stay longer than 90 days?
Not on a short-stay basis. For longer stays you need a national long-stay visa or residence permit from the country you plan to live in, for example for work, study or family reasons. Some countries also have bilateral agreements with certain nationalities that allow extra time in that country only. These are limited and complex, so check with the embassy before relying on one.
How do you use the official Schengen calculator?
The official Schengen calculator from the European Commission is simple once you know what each field means. Here is how to use it:
- Open the short-stay calculator on the European Commission’s border crossing page.
- Choose the mode. “Planning” checks a future trip; “Control” checks a past date, for example when you crossed a border.
- Enter the date of entry or control. In planning mode, this is the first day of your next trip.
- Add your previous stays. Type each entry and exit date. Include short trips, such as weekends.
- Press calculate. The Schengen calculator shows how many days you can still stay, and the latest date you can remain without breaking the rule.
- Try different dates if the result is too short, until you find a plan that works.
Keep screenshots of your results with your travel papers. They are not official proof, but they help you show that you planned carefully.
Should you trust a third-party Schengen calculator or app?
Many websites and mobile apps offer their own Schengen calculator. Some are helpful because they store your trips and send reminders, but they can contain errors or be out of date, for example with the list of member countries. Use them as a planning aid, but always double-check important trips with the official Schengen calculator. If your dates are close to the limit, check every day of the trip rather than only the last day.
Where do you find your past entry and exit dates?
You need accurate dates to get a correct result. Good sources include:
- Passport stamps, although these are being replaced by digital records
- Flight, train and ferry bookings in your email
- Hotel and accommodation receipts
- Bank card statements showing purchases abroad
- Photos on your phone, which show the date and often the location
If you travel often, keep a simple spreadsheet or note with every trip as you go. It makes using any Schengen calculator much quicker and more accurate.
Does the rule work differently for frequent travellers?
The rule is the same, but frequent travellers are more likely to run into it. Business travellers, digital nomads, people with partners in Europe and second-home owners often spend many short periods in the area. Because each short trip uses part of the allowance, they can reach 90 days sooner than expected. If this sounds like you, check your Schengen calculator before booking each trip, not just before long ones, and consider a national long-stay visa if you need more time.
Which Schengen calculator mistakes should you avoid?
- Forgetting that entry and exit days both count
- Counting in calendar months instead of a rolling 180 days
- Forgetting short trips, such as a weekend in Paris
- Assuming a multiple-entry visa allows longer stays
- Counting days in non-Schengen countries
- Checking only the first day of a long trip
A real example: planning a summer in Europe
Tom, a British teacher, spent 40 days in Spain from mid-March to late April. He wants to spend his summer holiday in Italy and Croatia from mid-July for 55 days. He enters both trips in the official Schengen calculator, which shows that on his last day he would reach 95 days in the rolling window. He shortens his summer trip by six days, adds a week in the UK at the start instead, and checks again. The result shows 89 days, so his plan is within the rule.

Frequently asked questions
How does a Schengen calculator work?
It looks back 180 days from a chosen date and counts the days you spent in the Schengen Area, to check you stay within 90.
Is there an official Schengen calculator?
Yes. The European Commission provides a free short-stay calculator on its website.
Do entry and exit days count?
Yes. Both count as full days.
Does time in the UK count towards the 90 days?
No. The UK and Ireland are not part of the Schengen Area.
Can I leave for one day and come back to reset my 90 days?
No. The rolling 180-day window means leaving briefly does not reset your allowance.
Does the rule apply if I have a multiple-entry visa?
Yes. You must still stay within 90 days in any 180-day period.
What happens if I overstay by a few days?
You can face a fine, removal or an entry ban, and it can affect future applications.
Do I need to show my calculation at the border?
No, but border officers can check your dates. Keeping your booking records and a copy of your calculation helps if there is a question.
Does the rule apply to children?
Yes. Every short-stay visitor, including children, is subject to the 90/180 rule, so count their days too.
