Calendar — entry 012 of 17

Non-Working Days

Verified Jul 2026

icsdb is an open-data repository of pre-built .ics calendar files enumerating official non-working days for France (and its overseas territories), Belgium, Germany, Ireland, Switzerland, the UK's home nations, and the US, maintained on GitHub rather than served through a query API. Consumers fetch the raw .ics files directly off raw.githubusercontent.com (which serves them with open CORS) and import them into any calendar tool or icalendar-parsing library; there's no key, rate limit, or cost, but the project itself has had no commits since 2020.
