Checkiday - National Holiday API

Checkiday - National Holiday API

Industry-leading Holiday API. Over 5,000 holidays and thousands of descriptions. Trusted by the World’s leading companies.

Tap into the World’s most trusted, complete, and accurate holiday data set. It is trusted by some of the largest companies including CNN, The New York Times, Huffington Post, Vice, USA Today, WikiHow, Daily Mail, Gizmodo, Esquire, Upworthy, and Lifehack.

Why is Checkiday the most accurate?

Our API is built by developers for developers. Our proprietary software ensures holiday dates are computed from predefined patterns, removing human error from the equation. Every single holiday that we have added to our database has been individually researched by one or more trained human researchers to ensure authenticity and accuracy. Our data has been used by tens of millions and reaches many more through our customers. If an error is discovered, we act quickly to verify and correct it.

Why is Checkiday the most complete?

We have been researching holidays for over 11 years! While we initially scraped the internet to find potential holidays to verify, we now have a database of 5,000 unique events. Due to our popularity, many events are now submitted directly to us by their creator or a fan.
