Short Stay Visa (90/180 Rule) Calculator
Track previous stays, check your current balance, and test a planned trip against the rolling 180-day rule used in many short-stay visa systems (including Schengen).
1) Add previous stays
2) Check date and planned trip
What this short stay visa calculator helps you do
If you travel frequently, it is easy to lose track of visa days. This calculator is designed to make that process clearer. You can enter your past travel periods, choose a reference date, and estimate how many days you have used under a short-stay framework based on a rolling 180-day window with a 90-day maximum.
The tool is especially useful for people moving between countries for tourism, business meetings, family visits, or remote-work transitions where short-term compliance matters. Instead of manually counting dates, you can get a quick, structured answer.
How the 90/180 rolling rule works
Rolling means the window moves every day
The most common mistake is treating the rule like a calendar half-year. It is not. For any given day, authorities can look back 180 days (including that day) and count how many days you were present. If the count exceeds 90, that day can be non-compliant.
- Window size: 180 days
- Maximum presence: 90 days in that window
- Counting style: entry and exit days are generally counted as days of presence
How to use this calculator
- Add each previous stay with a start and end date.
- Set a reference date to see your current used and remaining days.
- (Optional) Add a planned trip to test whether the full trip appears compliant.
- Review the result summary, including any potential violation date.
Example scenario
Suppose you stayed from January 10 to February 20, then again from April 1 to April 20. You now want to travel from June 1 to July 15. A proper rolling-window check may show that the first part is fine, but a later date in the trip might push you over 90 days.
That is why a good short stay visa calculator tests each day of a planned trip instead of only checking the trip start date.
Common mistakes travelers make
- Counting only full months and ignoring exact dates.
- Checking eligibility only at departure or arrival, not during the entire trip.
- Ignoring overlap between trips or same-day exits/entries.
- Relying on memory instead of records (boarding passes, stamps, tickets).
Important note
This calculator is an educational planning tool, not legal advice. Border authorities make final decisions based on official records and applicable law. Always verify with official immigration sources, especially if your itinerary is close to the limit.
