Holidata.net is a no-nonsense, ad-free provider of international holiday data under a Creative Commons License.
The purpose of holidata.net is to provide a source for free, reliable, international holiday data in machine-readable form via a stable API. The holidays are described in their native language, using UTF-8.
There really isn't an API, but rather a URL convention. Data can be obtained by using an HTTP request of the form:
https://holidata.net/<LOCALE>/<YEAR>.<FORMAT>
This allows the user to select the LOCALE, YEAR and FORMAT.
- The
LOCALEshould be one of the supported locales. - The
YEARshould be a four-digit value no earlier than 2011. - The
FORMATshould be one of:csv,json,yaml,xml.
Visit holidata.net for more information. Because the data is static content, the web server provides a status code that indicates success (200) or error (404).
