How this service works
Add/subtract business days to a date, or count working days between two dates. Weekend- and custom-holiday-aware (0=Mon..6=Sun).
Output
Returns the resulting date after adding or subtracting the specified number of business days, or returns the count of working days between two dates. The result accounts for weekends (configurable day offsets 0=Mon through 6=Sun) and any custom holidays provided.
Example use cases
Invoice payment due date calculation
“Our payment terms are net 30 business days from June 3, 2025. What's the actual due date, skipping weekends and the July 4th holiday?”
Project sprint deadline planning
“If a sprint starts on Monday July 7, 2025 and lasts 15 business days, what date does it end? Weekends are Saturday and Sunday.”
Count working days between two dates
“How many business days are there between August 1, 2025 and August 31, 2025, excluding weekends and the Labor Day holiday on September 1?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/business-days-calcWhen to prefer
Use this endpoint when you need calendar-aware date arithmetic that skips weekends and optional custom holidays — ideal for financial due dates, project scheduling, SLA calculations, or any workflow where 'days' means 'working days' rather than calendar days.
Side effects
- Invalid date format returns a 400 error
- Negative day count without explicit subtract operation may be ambiguous
- Custom holidays in unsupported format cause parsing errors
- Missing required fields (start date or operation) return validation errors
