Frequently asked questions
Are Saturdays and Sundays excluded?
Yes, by default. The count includes only Monday to Friday, minus any holidays you list.
Are the start and end dates included?
Yes. Both the start date and the end date are counted if they fall on a working day.
How do I add holidays?
Type one holiday per line, for example 2026-12-25. Only holidays inside the selected range affect the count.
Can I count a six-day work week?
This calculator uses the standard five-day week. For a six-day week, count calendar days and subtract only Sundays manually.
