Festivo Public Holidays
Festivo's Public Holidays API goes deeper than most competitors by resolving holidays down to city and regional level — not just country — across 250+ countries and 5,500+ states/regions, and can flag which holidays are substitute/observed days versus the original date. Requests carry an api_key query parameter against its EU-hosted gateway and return JSON, with support for multilingual holiday names and business-day/working-day calculations layered on top. A free tier covers 1,000 calls a day before paid plans (billed monthly, with EU invoicing/SEPA support) are needed.
