README

Working Days is a working days and business days API that counts the working days and non-working days for any country and month. Pass a two-letter country code and month number to get total counts, working date lists, and non-working days marked with holiday names.

The Working Days API provides a simple, reliable way to integrate working days functionality into your applications. Built for developers who need production-ready working days capabilities without the complexity of building from scratch.
