Access carefully maintained public holiday data for all Swiss municipalities – machine-readable, multilingual, and historised since 2003. Ideal for planning, analytics, and AI models.
Since 2003, we have been researching and maintaining public holiday and school holiday data with a strong focus on quality, long-term consistency, and transparency. Public PDF and iCal files serve as quality assurance, while your systems receive structured data via the API.
Long-term solution: our Public Holidays API is designed as a reliable foundation for business logic, planning, and reporting – not as a short-lived project.
Municipality-level detail: holidays are available for all Swiss municipalities, with mapping via postal code, BFS municipality ID, or GEO ID.
All relevant public holidays – including cantonal and local holidays where applicable
Municipality resolution – via ZIP code, BFS ID, or GEO ID
Annual requests – one calendar year per API call
Languages German, French, Italian, and English
Combinable with school holidays – identical parameter structure, same API architecture
Historical data since 2003 – ideal for statistics, time series, and AI models
Formats – JSON, XML, or CSV for system integration
Energy & grids – analyse load profiles and demand changes on public holidays
Transport & logistics – schedules, capacity, and incident management with holiday awareness
Retail & e-commerce – effects on orders, delivery times, and opening hours
HR & planning – absences, shift planning, international coordination
AI models & forecasting – holidays as features in time-series and forecasting models
REST API – simple HTTP-based interface
Formats – JSON, XML, CSV (ideal for back-ends, BI tools, and imports)
Multilingual – documentation in German, French, Italian, and English
Secure access – SSL/TLS encrypted, API-key authentication
All interfaces are defined according to OpenAPI 3.0 and integrate seamlessly with Swagger, Postman, and OpenAPI Generator.
The conditions depend on:
Data scope – individual cantons or all of Switzerland
Time range – current years, planning horizons, historical periods
Usage type – internal use or integration into your own apps / APIs (no public holidays API and no redistribution of raw data)
As a small independent provider, we ensure our data is not used to create competing services. Applications where public holiday data is the core of the product (holiday portals or public holidays APIs) are therefore not permitted.
Simply tell us which cantons / years and which type of usage you require (internal or integration) – we will gladly prepare a tailored offer.
