FAQ
Frequently asked questions
Are weekends excluded?
Saturday and Sunday are excluded by default. Either one can be counted as a business day with its checkbox.
Are public holidays excluded?
No. The current calculator has no country holiday dataset or custom holiday input.
Are both dates included?
The start date is considered, while the end date is excluded by default. Enable Include end date to count it when eligible.
What happens when both dates are the same?
The default result is zero because the end date is excluded. Including the end date counts that date according to its weekday settings.
Is this identical to spreadsheet NETWORKDAYS?
Not exactly. It provides weekend controls but does not accept a holiday range.
