How this service works
Verified, always-current business-day arithmetic for ~200 countries incl. subdivisions (German Bundeslaender, US states) and correct per-country weekend rules (e.g. Fri/Sat in Egypt). Informational only — verify legally binding deadlines with the competent authority. Not legal advice.
Output
A JSON object containing the input date, the country code, and the calculated previous business day as an ISO 8601 date string (e.g. {"date":"2026-04-06","country":"DE","previousBusinessDay":"2026-04-02"}), correctly accounting for national public holidays, regional holidays if a subdivision is specified, and the country's actual weekend structure.
Example use cases
Payment value date calculation
“Our payment system needs to know the previous business day before March 29, 2026 in Japan — can you look that up using country code JP?”
Legal filing deadline in US state
“What was the last business day before July 4, 2026 in California? Use country code US and region CA.”
Egyptian payroll cutoff
“Find the previous working day before January 1, 2026 in Egypt — they use a Friday–Saturday weekend, country code EG.”
Technical details
Endpoint
GEThttps://businessdayapi.com/v1/previous?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to step backward by exactly one business day from a reference date, especially when correct holiday and weekend handling across international jurisdictions (including non-standard weekends like Friday–Saturday in Egypt or Fri–Sat in the Gulf) is critical. Prefer it over generic date libraries when up-to-date, country-verified holiday calendars for ~200 countries and their subdivisions are required without maintaining your own holiday database.
Side effects
- Missing required 'date' or 'country' parameter returns a 400-level error
- Invalid ISO 3166-1 alpha-2 country code returns an error or unrecognized-country response
- Invalid or unsupported region subdivision code may return an error or fall back to country-level holidays
- Malformed date string (non-ISO format) returns a parsing error
- Payment of 0.001 USDC required; unpaid or failed x402 payment returns 402 Payment Required
- Very recent or future dates may have incomplete holiday data for some countries
