Business days & weekends calculators

Count weekdays and apply a holiday list that you supply.

Choose the right calculation

The default workweek is Monday to Friday. Date ranges use the inclusive and exclusive boundaries stated on each tool. No country holiday list is inferred, and special working Saturdays or weekends require a different calendar model.
