How this service works
Is it a business day? Weekend + public-holiday check with next business day — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object indicating whether the queried date is a business day for the given country, whether it falls on a weekend or public holiday (with holiday name if applicable), and the date of the next valid business day.
Example use cases
Payment settlement date validation
“We need to schedule a wire transfer for March 29 — is that actually a business day in Germany, or should we push it to the next working day?”
SLA deadline calculation for support team
“Our support SLA says we need to respond within one business day. Today is July 4 — is that a business day in the US, and if not, what's the next one?”
Contract execution date check
“The contract is dated November 11 — is that a business day in France, or does it fall on a public holiday? If it's a holiday, what's the next valid business day?”

Endpoint
POSThttps://twin.unykorn.org/geo/business-day?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine business day validity for a specific country with public holiday awareness, especially for scheduling payments, SLAs, contract dates, or any workflow that must avoid weekends and national holidays. Prefer this over a simple weekday check when public holidays matter and when you need the next business day fallback date.
Side effects
- Missing or invalid country ISO-2 code returns an error
- Invalid date format (not YYYY-MM-DD) causes a parse error
- Unsupported or unrecognized country codes may return incomplete holiday data
- Edge cases around regional holidays (state/province-level) may not be covered
