What is this?
A Schengen Calculator tracks the 90/180 rule, which allows visa-exempt visitors up to 90 days in the Schengen Area in any 180-day period. It works out how many days you have used, how many remain, and whether a planned trip would breach the limit.
How to Use the Schengen 90/180 Calculator
Visitors who do not need a visa for the Schengen Area may stay up to 90 days in any 180-day period. The catch is that the 180 days roll: there is no fixed block that resets on a particular date. For any day you are in the area, the authorities look back over that day and the 179 before it and count how many of those you spent inside.
Enter your past trips and this works out how many days you have used, how many are left, and whether a trip you are planning would break the limit.
1. Set the Date to Check
Usually today, or the date you expect to arrive at a border. The whole calculation is relative to this date, because the 180-day window ends on it.
2. Enter Your Past Trips
Add the entry and exit date of every stay in the Schengen Area over the last six months. Trips older than 180 days no longer count, but including them does no harm.
3. Add a Planned Trip
Optional. Enter the dates you are thinking of travelling and the calculator checks every single day of that trip against the rule, not just the last one.
4. Read Your Position
You get days used out of 90, days remaining, the longest unbroken stay you could start on your chosen date, and the earliest date you could next enter if you are already at the limit.
Key Formulas Used in the Calculator
The Rolling Window
Window=Chosen Day+179 Days Before It
180 days counted backwards, inclusive of the day itself. It moves forward with every day, which is why allowance returns gradually rather than resetting all at once.
Days Used
Days Used=∑(Days Within the Window Spent in the Schengen Area)
Entry and exit days both count in full. Arriving on 1 January and leaving on 3 January is three days, not two.
Days Remaining
Days Remaining=90−Days Used
This is the number you could still spend if you entered on the day you are checking.
Example Calculation
1 Jan to 31 Mar is 90 days: full on 31 Mar, still full on 29 Jun, 89 on 30 Jun
A 90-day stay uses the whole allowance. The first day only leaves the window on 30 June, 180 days after 1 January counting inclusively, so allowance then returns one day at a time.
Benefits

Merges overlapping trips so no day is counted twice
Checks every day of a planned trip, not only the end date
Shows the earliest date you could next enter
Shows which part of each trip falls inside the window
Handles leap years and daylight saving correctly

Tips to Get the Best Deal
Both the arrival and departure day count - this is the most common mistake
The window rolls, so your allowance returns gradually rather than resetting
Include every Schengen country - the 90 days are shared across all of them
Ireland and Cyprus are in the EU but not in Schengen
Keep your passport stamps or entry records as evidence
Check a planned trip before booking, not after
A long trip can breach in the middle even if it looks fine at the end
Frequently Asked Questions (FAQs)
What is the Schengen 90/180 rule?
Visa-exempt visitors may spend up to 90 days in the Schengen Area in any 180-day period. The 180 days roll: for any given day, the authorities count how many of the previous 180 days including that one you spent inside the area.
Does the day I arrive count?
Yes, and so does the day you leave. Arriving on 1 January and departing on 3 January is three days, not two. Counting only the nights is the single most common way people end up over the limit.
Does the 180-day period reset?
No. It is a rolling window, not a fixed block. If you use all 90 days between 1 January and 31 March, your allowance does not reset on a particular date - it comes back one day at a time from 30 June onwards as each earlier day falls out of the window.
Are the 90 days per country or for the whole area?
For the whole Schengen Area combined. Days in France, Spain and Germany all draw on the same 90-day allowance. Ireland and Cyprus are in the EU but outside Schengen, so time there does not count.
What happens if I overstay?
Consequences range from a fine to a formal entry ban, and an overstay is recorded against you for future applications. Even a short overstay can cause problems at later border crossings, so it is worth checking before you travel.
Can I check a trip before booking it?
Yes. Enter your planned entry and exit dates and the calculator tests every day of the trip. A long stay can breach the limit part-way through even when the totals look acceptable at either end.
Is this calculator official?
No. It implements the rule as set out in the Schengen Borders Code, but border officers decide based on their own record of your entries and exits. Treat the result as planning information rather than a guarantee of admission.
