How this service works
Count business days (Mon–Fri) between two dates, with weekend and holiday breakdown. Provide a country code and real public holidays (via Nager.Date) are excluded too. Use this when an agent needs to working days between dates, optionally minus public holidays.
Output
Returns a structured object containing the total number of business (working) days between the two dates, the number of weekend days excluded, the number of public holidays excluded (if a country code was provided), and a list of the specific public holidays that fell within the range.
Example use cases
Project deadline estimation
“How many working days do we have between February 10 and March 28, 2025, excluding UK public holidays? I need to figure out if there's enough time to complete the project.”
Invoice payment terms compliance
“A client invoice is dated January 15, 2025 and has net-30 business days payment terms — what's the exact due date if we exclude US holidays?”
HR notice period calculation
“An employee handed in their resignation today, April 7, 2025. If their contract requires 20 business days' notice, excluding German public holidays, what is their last working day?”

Endpoint
GEThttps://agentstoolshub.com/api/v1/live/business-days?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise count of working days between two dates, especially when you need to exclude public holidays for a specific country. It is ideal for deadline calculations, SLA tracking, invoice payment terms, HR notice periods, and project scheduling. Prefer this over manual date arithmetic whenever country-specific holiday data matters.
Side effects
- Missing start or end date parameter returns a 400 error
- Invalid date format (non-ISO 8601) causes a parse error
- Unsupported or invalid country code returns an error or falls back to no holiday exclusion
- End date before start date may return zero or a negative count
- Network errors to Nager.Date public holiday API could cause holiday lookup to fail
