Who is it for?
Travel and visa agencies, travel blogs, community sites and universities welcoming international students. The 90/180 rule is one of the most-asked travel questions, and the widget answers it on your page.
How are days counted?
Under the Schengen Borders Code: no more than 90 days in any 180-day period, with both entry and exit days counted. Everything is calculated in the visitor’s browser.
Is it free?
Yes, free and ad-free. We only ask you to keep the small credit link below it.
Does it collect visitor data?
No. No cookies, no tracking; dates never leave the visitor’s browser.
Does it replace the official calculator?
It is a planning tool. The European Commission’s official calculator remains the reference.
