Worldwide Holidays and Observances RESTful API

What it does

Giving you access to public, local, and bank holidays, as well as observances, across more than 230 countries, over 3,300 states, and in more than 100 languages. We use latency based DNS routing to serve over 90% of all requests handled in less than 10ms. Our cloud-based auto-scaling servers can handle over half a billion API queries per day. Our data is aggregated and verified from multiple sources and updated regularly. Pick the workflow closest to yours. Every one runs on the same REST endpoint, the same API key, and the same monthly quota. Filter to national holidays only and drop the observances, seasons, and religious dates you do not pay out for. One request per country per year. Ask…from calendarific.com
