Calculate the number of weekdays between two dates. The tool counts Monday through Friday and optionally removes public holidays or office closures that you enter manually.

How it works

Both dates are counted when they fall on a weekday. Public holidays are not excluded by default; type specific dates in YYYY-MM-DD format if necessary.

This is a basic weekday calculator, not a determination of contractual working days or legal deadlines.

Frequently asked questions

Does it automatically exclude UK bank holidays?

No. Enter any bank holidays you want excluded, because calendars differ across UK nations and years.

Does Saturday count?

No. This calculator counts Monday to Friday only.

Weekends and public holidays

The calculation counts Monday to Friday between the selected dates, including the starting and ending dates when they are weekdays. Enter holidays explicitly in the YYYY-MM-DD format to exclude them from the count.

National holidays, regional closures, bank holidays and employer-specific work schedules are not automatically loaded. For plain calendar days instead, use days between dates.

Include or exclude boundary dates

You can decide whether to count the earliest date and latest date in the range, independently, using the two checkboxes. By default both dates are considered; Saturdays, Sundays and any valid holidays you enter are excluded from the result. The calendar range is sorted chronologically before calculation, even if you enter the later date first. The calculator does not automatically know local public holidays or employment contract rules.
