Frequently asked questions
Is this the same as the Business Days Calculator?
Yes — "working days" and "business days" refer to the same Monday-Friday count. This page exists for the alternate common search term.
Does this account for public holidays in my region?
No — only weekends are excluded. Subtract known public holidays from the result manually, since holiday calendars vary widely by country and region.
What is this commonly used for?
Estimating project delivery timelines, notice periods, or shipping/processing windows that are defined in working days rather than calendar days.
