How it works

This calculator shows you the date that was exactly 180 days before any reference date. Pick a date (today by default) and the answer appears.

Why 180 days matters: the Schengen 90/180-day rule uses a rolling 180-day window. From any date, you look back 180 days and count every Schengen day inside that span. Days outside that 180-day span do not count toward your 90-day allowance.

So the date 180 days before your reference point is the start of your rolling window on that date. Trips that ended before this date no longer count. Trips that started after it count in full. Trips that overlap the boundary count only from the start of the window onwards.

The calculation is plain calendar arithmetic: 180 calendar days, including weekends and public holidays. There is no business-days exception and no rounding by month. The Schengen Borders Code specifies exactly 180 days, not six months, because months vary in length.

If you want this 180-day window combined with your past trips, the Days Remaining calculator does that automatically. This tool is for working backwards from a specific date.

Frequently asked questions

Is the UK in the Schengen Area?
No. The UK has never been part of the Schengen Area, even when it was an EU member. Since Brexit (31 January 2020), British citizens travelling to Schengen countries are treated as third-country nationals and subject to the 90/180-day rule like any other non-EU visitor.
How many days can I stay in the Schengen Area?
Up to 90 days within any rolling 180-day period, counted across all Schengen countries combined: they share a single 90-day budget, not 90 days each.
How does the rolling 180-day window work?
The window isn't fixed; it slides. From any given date (today by default, or whatever you set with the "As of" picker), the calculator looks back 180 days and counts every day you spent inside Schengen during that span. As you move the reference date forward, older trips eventually fall outside the window and stop counting. Add your trips above to see how the rolling window applies to your dates.
Are the EU rules 90 days per calendar year?
No, this is a common misconception. The 90 days don't reset on 1 January. The rule uses a rolling 180-day window: from any given date, look back 180 days and the total time inside Schengen during that span must be 90 days or fewer. As older days age past the 180-day mark, they roll out of the window and become available again. Use the calculator above to check how the window applies to your specific trips.
How do my 90 days build back up?
Used days roll out of your 90-day budget gradually rather than resetting all at once. Each day you spend outside the Schengen Area, the oldest day in your 180-day window inches further into the past. Once a used day passes the 180-day mark, it falls outside the calculation and becomes available again. The calculator above highlights which days will fall outside the window next, so you can see when your next allowance frees up.
Do entry and exit days both count?
Yes. The day you enter and the day you exit are each counted as a full day inside the Schengen Area, regardless of what time you cross the border. A trip from 1 May to 5 May counts as 5 days, not 4. This is defined under EU Regulation 2016/399 and the calculator applies it by default.
Can I split my 90 days across multiple trips?
Yes. The 90 days don't have to be consecutive. You can divide them across as many trips as you like, but every trip's days count toward the same total, and any trip that started within the previous 180 days is still on your tab.
How do I calculate my Schengen days?
Add every Schengen trip you've taken (or planned) within the last 180 days, including the entry and exit dates. The calculator does the maths for you and shows how many days you have remaining in your current 180-day window. You can also check a future date with the "As of" picker to see if you'll be compliant when you arrive.
