How this service works
Public and bank holidays for 100+ countries, and the business-day answer behind them. Returns holidays[] with localName, name, global and types; pass ?date= and it also answers isBusinessDay with nextBusinessDay and previousBusinessDay, walking weekends and year boundaries. Requires ?country=<ISO 3166-1 alpha-2, e.g. US>; optional ?date=YYYY-MM-DD or ?year=1975..2100. Errors: 400 bad_country (a 3-letter code like USA is rejected)|bad_date|bad_year, 404 unknown_country.
Output
A list of holidays for the country and year with each holiday's local name, English name, date, whether it is nationwide, and which regions observe it. When a date is supplied, also returns a boolean isBusinessDay flag plus the dates of the next and previous business days (crossing weekends and holidays, including across year boundaries).
Example use cases
Settlement date calculation for finance
“We have a trade settling in 3 business days from November 27 2025 in the US — can you work out the exact settlement date, skipping weekends and any US public holidays?”
Payroll scheduling across year boundary
“Our payroll is due on December 31 2025 in the UK — is that a business day, and if not, what's the previous business day we should use instead?”
SLA deadline verification for logistics
“I need to confirm whether August 15 2025 counts as a working day in France for our delivery SLA — and if it's a holiday, what's the next business day?”

Endpoint
GEThttps://x402.donnyautomation.com/holidaysWhen to prefer
Choose this endpoint when you need authoritative public and bank holiday data for 100+ countries with direct business-day computation built in — avoiding the need to implement your own weekend/holiday walking logic. It is especially useful for settlement, payroll, SLA, and scheduling agents that need to cross year boundaries or handle regional holiday distinctions in a single call.
Side effects
- Missing or invalid country code returns an error — must be ISO 3166-1 alpha-2
- Year outside supported range 1975–2100 may return an error or empty result
- Invalid date format (not YYYY-MM-DD) returns a parsing error
- Network or payment (x402) failure prevents the response
- Some countries may have incomplete or unofficial regional holiday data
