Working Days & SLA Calculator API

What it does

Stop hard-coding calendars. A simple API to calculate target dates by skipping weekends, national/regional public holidays, and financial stock market closures (NYSE, etc.). Ideal for E-commerce, HR SaaS, and Fintech.

### Stop hard-coding calendars. When your product promises delivery in *N business days*, real life is messy: weekends, changing legal holidays, and country-specific calendars break naive date math. This API gives you production-ready business-day calculations in one call: - ✅ Add or subtract working days. - ✅ Skip weekends automatically. - ✅ Skip country public holidays (US/CN/GB/... and more). -
