Frequently Asked Questions
Are weekends excluded from business days?
Yes. The business-days figure counts Monday to Friday only and excludes Saturdays and Sundays. Public holidays are not removed.
Does the order of dates matter?
No. If you enter the end date before the start date, the tool automatically swaps them and shows the absolute difference.
