How this service works
Add business days to a date or count the business days between two dates, Monday-Friday, skipping holidays you list.
Output
Returns the resulting date (when adding days) or the count of business days (when counting between two dates), along with the weekday name, list of holidays that were skipped, number of business days added, and a human-readable summary of the calculation.
Example use cases
Contract deadline calculation
“Our contract was signed on April 1, 2025 and requires delivery within 30 business days. Skipping April 18 and May 26 as holidays, what is the actual deadline date?”
Invoice payment window
“How many business days are there between May 5, 2025 and May 30, 2025, excluding May 26 as a holiday? I need to know if a 'net 18 business days' payment term is being met.”
Project milestone planning
“I need to schedule a milestone 10 business days before our June 20, 2025 launch. What date is that, skipping June 19 as a holiday?”
Technical details
Endpoint
GEThttps://timezone-time.x402tookit.com/business-days?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise business-day arithmetic that respects weekends and custom holiday lists, such as calculating contract deadlines, payment terms, regulatory filing windows, or project scheduling. Prefer this over manual calendar counting or generic date-difference APIs when holidays must be excluded and business-day accuracy is required.
Side effects
- Missing required 'start' query parameter returns an error
- Neither 'end' nor 'add_days' provided results in an ambiguous request error
- Malformed date strings (non-YYYY-MM-DD format) cause parsing errors
- Negative add_days with insufficient prior business days may return unexpected results
- Invalid holiday date formats in comma-separated list may cause holidays to be ignored
