FAQ
Common questions and answers about this topic.
How do I calculate business days between two dates?
Switch to "Difference" mode, enter the start and end dates, then check "Exclude weekends". The result shows both total calendar days and working days with weekends removed.
Can I exclude holidays from the calculation?
Yes. Use the "Custom excluded dates" section to add specific dates like national holidays. These dates are skipped in both add-time and difference calculations, in addition to any weekend exclusion.
What is the difference between calendar days and working days?
Calendar days count every day including weekends and holidays. Working days exclude weekends and any custom excluded dates, giving you the actual number of business days in the range.
How do I subtract days from a date?
In "Add time" mode, click the "Backward" direction toggle. Enter your starting date and the number of days or hours to subtract. The result will show the date in the past.
