Before you pick one
Holiday lists change when governments announce new dates. Fetch the year you need at build time or once a day rather than hard-coding it.
Open an API’s page to see the exact request we send, the answer it gave, and how many of the last 30 days it was up. If it is marked CORS you can run the request from the page itself.
