An explainer from The Local addresses common questions about the Schengen area’s “90-day rule,” a framework that governs short stays for travellers who do not require a visa. The rule limits non-EU/Schengen visitors to spending no more than 90 days within any rolling 180-day period in the Schengen area. The piece focuses on why the system is confusing and how travellers can think about day counting when planning trips. It describes the general approach used to assess eligibility: authorities consider the total time spent across the Schengen countries during the relevant six-month window rather than resetting the count after each entry or after moving between member states. The explainer also highlights practical issues travellers ask about, such as how days spent in the region are counted and what happens when trips overlap the 180-day timeframe. By summarising frequently asked questions, the article aims to help travellers check whether their itinerary stays within the permitted limit.
