How this service works
Count business days between two dates, skipping weekends and your holiday list, NETWORKDAYS style.
Output
Returns a JSON object containing the count of business days, calendar days, and weekend days in the range; the list of holidays that were applied; whether both endpoints were counted (inclusive flag); a summary string; and metadata such as source and timestamp.
Example use cases
Contract deadline business day count
“My contract starts on February 3, 2025 and ends on April 30, 2025 — how many business days is that, excluding weekends and these company holidays: 2025-02-17, 2025-04-18?”
Project sprint planning calendar
“We're planning a sprint from March 10, 2025 to March 28, 2025. How many actual working days do we have, skipping Saturday and Sunday but also March 14 and March 17 which are company off-days?”
Invoice payment due date compliance
“Our payment terms say 30 business days from the invoice date of May 1, 2025 to May 30, 2025 — can you tell me exactly how many business days fall in that window, excluding weekends and Memorial Day on May 26?”
Technical details
Endpoint
GEThttps://work-time-calc.x402tookit.com/business-days?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a server-side, authoritative business-day count between two dates with full control over which days are treated as the weekend and a custom holiday list of up to 500 dates — equivalent to Excel's NETWORKDAYS function. Prefer it over client-side date math when accuracy, auditability, or support for non-standard work weeks (e.g. Sun–Thu) matters.
Side effects
- Missing required start or end query parameter returns an error
- Malformed date strings (non-YYYY-MM-DD) cause a parsing error
- End date before start date returns a negative business day count (by design)
- Invalid holiday date formats in the comma-separated list may be silently skipped or cause an error
- More than 500 holidays supplied may be rejected
- Invalid weekend day values (not sat/sun/mon etc.) cause a parameter error
