How business days are counted
This calculator counts every day from Monday to Friday between the two dates you pick and excludes Saturdays and Sundays. It walks through the range one day at a time, checking the weekday for each date: if a day falls on a weekend it is added to the weekend count, otherwise it counts as a business day. The total days figure is simply every calendar day in the range, so business days plus weekend days always add up to it.
The calculator does not include public holidays. Bank holidays, national days and regional closures vary widely from country to country and even region to region, so a weekday that is a holiday where you are will still be counted here as a business day. If holidays matter for your deadline, count how many fall on weekdays inside your range and subtract them from the business day figure.
Note: The end date is included by default. Untick "Include the end date" when you want to measure the gap up to but not counting the final day, for example when counting working days remaining before a deadline.
Frequently asked questions
What counts as a business day?
A business day is any weekday from Monday to Friday. This calculator counts those days between your two dates and leaves out Saturdays and Sundays.
Does this include public holidays?
No. It only removes weekends and does not know about national or local public holidays, so subtract any bank holidays that fall on weekdays yourself.
Does it count the start and end dates?
The start date is always counted. The end date is included by default, but you can untick "Include the end date" to stop the count one day earlier.
