How Working Days Calculator works

Count working days between dates or add business days using custom weekend days and optional local holiday dates.

The formula

Working days are calendar days that are neither selected weekend days nor listed holidays falling on a working weekday.

A practical example

Count Monday through Friday between two dates, then exclude a locally entered public holiday.

Important limitations

No country holiday service is queried. Only the holiday dates you enter for the current calculation are excluded.

Frequently asked questions

Are holidays detected automatically?

No. Add relevant dates manually; V1 deliberately does not use country holiday APIs.

Can weekends be Friday and Saturday?

Yes. Choose any one to six days as the weekend.
