How this service works
Add or subtract N business days from a date, skipping weekends and your holiday list, WORKDAY style.
Output
Returns a JSON object with the computed result date (YYYY-MM-DD), the weekday name of that date, the number of calendar days actually moved, whether the start date was itself a business day, a plain-English summary, and metadata fields like source, asOf, and any degraded-mode warnings.
Example use cases
Contract closing date calculation
“Our deal signed on 2025-07-01 — what's the closing date if the contract requires 45 business days to close, skipping weekends and these US holidays: 2025-07-04, 2025-09-01?”
Invoice payment due date
“An invoice was issued on 2025-06-10 with net-30 business days payment terms. What's the actual due date, excluding Saturdays, Sundays, and 2025-06-19?”
Project deadline countdown backwards
“I need to finish a deliverable that's due 2025-08-15 — what date do I need to start if I work backwards 10 business days, skipping weekends?”
Technical details
Endpoint
GEThttps://work-time-calc.x402tookit.com/add-business-days?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compute a future or past date by counting only working days — equivalent to Excel's WORKDAY function — especially when you need custom holiday exclusion lists and configurable weekend definitions. Prefer it over general date-math APIs when business-day semantics (skipping non-working days) are required rather than simple calendar-day arithmetic.
Side effects
- Missing required 'date' or 'days' parameters returns an error
- Invalid date format (not YYYY-MM-DD) causes a parsing error
- 'days' value outside -20000 to 20000 range is rejected
- More than 500 holidays provided exceeds the limit
- Malformed holiday date strings in the list cause validation errors
- Payment failure (x402) returns 402 Payment Required
