Examples

Frequently Asked Questions
Does "exclude weekends" also exclude holidays?
No. This calculator only excludes Saturdays and Sundays. Public holidays are still counted as weekdays. For holiday-aware calculations, you would need to manually subtract known holidays.
Why does the day count differ by one from what I expect?
This usually depends on whether you include the end date. Counting "from January 1 to January 3" yields 2 days exclusive or 3 days inclusive.
