Frequently Asked Questions
How do you calculate working days?
Working days (business days) are calculated by counting all days between two dates and excluding weekends (Saturday and Sunday). You can also exclude public holidays for more accurate project planning.
Do working days include weekends?
No. Working days specifically exclude weekends (Saturday and Sunday). A standard work week is 5 days (Monday through Friday). This calculator automatically skips weekend days in its count.
How many working days are in a year?
Typically 260-262 working days in a year (52 weeks × 5 days). However, this varies by country and year due to public holidays. In the US, with federal holidays, it's usually around 250 working days.
Can I exclude holidays from the calculation?
Yes! This calculator allows you to optionally exclude common holidays. You can select which holidays to exclude (New Year's, Christmas, etc.) for a more accurate business days count.
What is the difference between calendar days and working days?
Calendar days include every day of the week (7 days), while working days only count Monday through Friday (5 days per week), excluding weekends. For project planning, working days give a more realistic timeline.
