How this service works
Check if a specific date is a business day in a given country. Accounts for weekends and public holidays. Also returns the next business day if the given date is not one.
Output
Returns a boolean indicating whether the queried date is a business day in the given country, along with the next business day date if it is not, accounting for both weekends and country-specific public holidays.
Example use cases
Automated payment scheduling across time zones
“I need to schedule a payment for January 15th, but make sure it lands on a business day in Germany. Can you check if that date works, and if not, what's the next available business day?”
Contract deadline validation for international deals
“Our contract with our French partner has a deadline of July 14th next year. Can you verify that's actually a business day in France, or should we push it to the next working day?”
Payroll processing for multi-country teams
“We're setting up automated payroll transfers for December 26th. Check if that's a business day in both the UK and Canada, and if either one is a holiday, tell me when we should process those payments instead.”

Endpoint
GEThttps://api.strale.io/x402/business-day-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify whether a specific date is a valid working/business day in a particular country, especially when scheduling payments, contract deadlines, or automated workflows that must land on a business day. Ideal for multi-country business logic where public holiday calendars vary.

- Unsupported or invalid ISO country code returns an error or unexpected results
- Dates far in the future may have incomplete public holiday data
- Network or service unavailability returns a 5xx error
