## About

## What it does
Working Day Calculator counts business days between two dates for a given country. Send a `country`, `start`, and `end`, and get back a breakdown of the date range in calendar terms and working-day terms.

The response includes `total_days` for the full inclusive range, `weekends` for Saturday and Sunday days, `holidays` for public holidays that fall on weekdays, and `working_days` for the resulting Mon–Fri count after those holidays are removed. That makes it easy to calculate lead times, SLA windows, payroll periods, project timelines, and delivery estimates without hard-coding your own calendar logic.

Use Working Day Calculator when your app needs country-aware date math. For example, you can verify whether a support deadline lands on a working day, estimate how many business days remain in a procurement cycle, or compute working-time reports for internal tooling.

Because the country is part of the request, the result can reflect local public holidays rather than just weekdays. That helps keep schedule calculations consistent across regions and avoids off-by-one errors in date ranges.
