What is a working day?

A working day (or business day) is typically a weekday (Monday through Friday) that is not a public holiday. This calculator allows you to customize which days are considered working days and automatically excludes federal holidays based on your selected country.

Which countries' holidays are supported?

The Working Days Calculator supports federal holidays for the United States, United Kingdom, Canada, Australia, Germany, France, India, Japan, and many other countries. You can also add custom holidays for company-specific non-working days.

Can I customize the work week?

Yes! The calculator allows you to customize which days of the week are working days. While the default is Monday-Friday, you can adjust this to match your company's work schedule, including 6-day work weeks or alternative schedules.

How are holidays calculated?

The calculator includes official federal holidays for each country. These holidays are automatically excluded from the working day count. You can view a list of holidays that fall within your date range and add custom holidays as needed.
