Open in Claude

Calendera answers questions about public and school holidays across Europe — 38 countries and their regions, in the languages each country publishes them in. Ask which days are public holidays in Bavaria next year, when the school holidays fall in Vaud, or where in Europe 3 October is a day off, and Claude answers from the dates the regions actually keep: school terms, days moved off a weekend and each region's own holidays included; town festivals that are nobody's day off left out. Where a country's regions keep different holidays — Germany, Switzerland, Spain, Italy and others — the answer says so and names the regions, rather than passing a national list off as anyone's year. Ask to see a year and it opens as a calendar in the conversation: public holidays, school holidays and bridge days marked, in the region's own language. Its leave planner shows how far a few days off go — click the days you would take, see how many days in a row they add up to, and share the plan into the conversation. The dates come from the OpenHolidays API (Open Database Licence), gov.uk (Open Government Licence) and the statutes of Cyprus, Denmark, Greece and Türkiye, republished by calendera.org and refreshed every morning.
