Namedays Calendar vs The Calendar
This API looks up which name(s) are celebrated on a given calendar date — or which date a given name falls on — across roughly 40 countries' nameday traditions, via a documented OpenAPI v2 surface (/today, /tomorrow, /yesterday, /getdate) served as JSON. It's a personal open project by its maintainer (Michal Abaline) with no signup, no API key, and no rate limiting, positioned as a lighter keyless alternative to older nameday lookup services.
The Calendar publishes pre-generated, static JSON (and downloadable .ics) files for US federal and all-50-state holidays (2025–2028), 30 countries' public holidays, plus FOMC meeting dates, US tax deadlines, market holidays, and key-date calendars for a dozen sports leagues. Every one of its 99 documented endpoints is a flat file behind Cloudflare, so there's no authentication, no rate limit, and CORS is wide open — licensed CC BY 4.0 as long as you link back.
