## About

## What it does

Working Day Counter calculates how many working days fall between two dates for a given country. Send `country`, `start`, and `end`, and it returns the calendar-day span plus a breakdown of `working_days`, `weekends`, and `holidays`.

Use it when you need date-based business logic that respects local public holidays. For example, payroll systems can compute pay periods, procurement workflows can estimate SLA windows, and scheduling tools can skip non-working days when assigning deadlines.

The response is simple and explicit. `total_days` gives the inclusive calendar range, `weekends` counts Saturday and Sunday days in that range, `holidays` counts public holidays that fall on weekdays, and `working_days` gives the final Mon–Fri count after excluding those holidays.

Working Day Counter is useful anywhere you need consistent working-time calculations without maintaining your own holiday calendar for every country.
