About

Nager.Date is an open-source API for public holidays by country code and year, with holiday types and subdivisions, CORS and no key. Free for private and non-profit projects; commercial use needs an active GitHub sponsorship, as do the Docker and NuGet offline builds. Asia coverage is partial.

What you can do with it

Fetch a country's national holidays for a year with one keyless request
Skip national holidays when counting business days in a scheduling app
Show the next national holidays per country in a web page with CORS

Get started

Call /api/v4/Holidays/{countryCode}/{year} without a key
Sponsor the project on GitHub before any commercial use

Example

curl "https://nagerholidays.com/api/v4/Holidays/TR/2026"
