Real-World Use Cases

Non-EU nationals visiting the Schengen Area must follow the 90/180 rule: they can stay for up to 90 days within any rolling 180-day period. This calculator helps travelers track their used days and plan future trips without risking an overstay.

A digital nomad from Brazil spent 45 days in Portugal from January 15 to February 28, then wants to return on April 10. The calculator shows that on April 10, the 180-day window looks back to October 12 of the previous year. The 45 days from January and February fall within this window, leaving 45 days remaining.

A tourist from India visits France for 30 days in March, Italy for 20 days in May, and wants to visit Germany in August. By entering all three trips, the calculator shows whether the August trip would exceed 90 days in the rolling window, and if so, by how much.

A business traveler from the US makes frequent short trips to Schengen countries for meetings. Two 5-day trips in January, one 7-day trip in March, and a 10-day trip in June. The calculator tracks all trips and shows the running total against the 90-day limit.

A retiree from Australia wants to spend the summer in Spain. They plan to enter on June 1 and want to know the maximum number of days they can stay. The calculator shows the longest continuous stay possible from June 1, considering any previous trips in the preceding 180 days.

How It Works

The 90/180 rule uses a rolling window, not a fixed calendar period. For any date you check, the calculator looks back 180 days (the previous 179 days plus the reference date itself) and counts how many of those days you were physically present in the Schengen Area.

To use the calculator, enter each trip with its entry date, exit date, and optionally the country. The tool marks every day from entry to exit (inclusive) as a Schengen presence day. It then calculates how many of those days fall within the 180-day window ending on your reference date.

Both the entry day and the exit day count as full days of presence. If you enter on March 1 and exit on March 10, that is 10 days counted toward your 90-day limit. There is no partial day counting.

The longest stay calculation finds the maximum number of consecutive days you can stay starting from the reference date without exceeding 90 days in any rolling 180-day window. This accounts for your existing trip history, so the result reflects your actual available days.

The overstay detection checks every day you were present and flags any day where the preceding 180-day window contains more than 90 presence days. This catches both historical overstays and helps you avoid future ones.

Step-by-Step Usage Guide

1. Enter each past and planned trip using the entry date, exit date, and optional country fields, then click Add Trip.
2. Set the reference date to the day you want to check. By default, it is today. Change it to a future date to plan ahead.
3. The Days Used panel shows how many Schengen days fall within the 180-day window ending on the reference date.
4. The Days Remaining panel shows how many more days you can stay (90 minus days used).
5. The Longest Stay Possible panel shows the maximum consecutive days you can stay from the reference date without exceeding the 90-day limit.
6. Check the calendar view for a visual representation of your presence days and the 180-day window.
7. If an overstay is detected, a red warning panel appears with the dates and days used. Review this carefully.

Common Mistakes and Edge Cases

Things to keep in mind

• Entry and exit days both count: A trip from March 1 to March 10 is 10 days, not 9. Both the first and last day are counted as full presence days.
• The window is rolling, not fixed: The 180-day period is not January 1 to June 30. It moves with each day you check. On April 10, the window is October 12 to April 10. On April 11, it shifts to October 13 to April 11.
• Multiple short trips add up: Five 5-day trips across different months can use 25 days of your 90-day allowance. The calculator tracks all trips together, not individually.
• Border crossings without stamp: If you travel between Schengen countries (e.g. France to Germany), there is no border check. But all days in any Schengen country count toward the 90-day limit, regardless of which country you are in.
• Overstay consequences: Exceeding 90 days can result in fines, deportation, entry bans, and future visa denials. The Schengen Information System (SIS) records overstays, and they can affect future travel to all Schengen countries.
• Reference date matters: If you check days used on July 1 but plan to enter on August 1, check the reference date as August 1 instead. The window shifts, and trips from January may no longer count.
