Counting working days

A business days counter counts only the weekdays between two dates, Monday through Friday, and skips Saturdays and Sundays. That matters whenever a timeline is measured in working days rather than calendar days — shipping and delivery estimates, payment and notice periods, service-level deadlines, and project schedules are almost always quoted this way.

This tool counts both the start and end date when they fall on a weekday, the same way a spreadsheet's NETWORKDAYS function does, and also shows the total number of calendar days and how many of them were weekend days. It does not remove public holidays, because those differ from one country and region to the next, so if a holiday falls inside your range, subtract it from the business-day total.

Frequently Asked Questions

Quick answers about counting business and working days.

Is this business days calculator free?

Yes. It is completely free, with no sign-up, and it runs entirely in your browser.

What counts as a business day?

A business day is a weekday, Monday through Friday. Saturdays and Sundays are treated as weekends and are not counted.

Does it include the start and end date?

Yes. Both the start and end date are counted if they fall on a weekday, the same way spreadsheet functions like NETWORKDAYS work.

Does it skip public holidays?

It only skips weekends. Public holidays vary by country and region, so if you need to exclude them, subtract the holiday count from the result.

Can I count working days until a deadline?

Yes. Set today as the start and the deadline as the end to see how many working days you have left.

How is this different from the days between dates tool?

Days between dates counts every day. This calculator counts only working days, skipping weekends, which is what most delivery and deadline estimates use.

Are the dates I enter stored anywhere?

No. The calculation happens in your browser, so the dates never leave your device.

Can I use it on my phone?

Yes. It works in any mobile browser, with nothing to install.
