Business Days Calculator
How many business or working days between two dates?
Non-working days out, your own public holidays out, and every removed day listed — so you can see exactly what the count is made of rather than trusting a number.
How this is worked out
- A holiday landing on a non-working day is not double-counted — it is listed separately, since it costs no working day.
- Where your holidays move to a substitute day, enter the date actually taken off; that is the one that changes the count.
Questions people ask
The things that come up about business days calculators, answered plainly.
Which holidays are removed?
The ones you paste in. There is no country list, because no finite list would be right for most of the world — and a wrong default produces a confident answer that is silently incorrect. Paste your dates one per line and the count is right for you.
Does it count the start and end dates?
The start date is counted if it is a working day; the end date is not, which matches how a deadline of "ten business days" is usually read. The inclusive toggle adds it back.
What if my working week is not Monday to Friday?
Pick another. Sunday-to-Thursday, Monday-to-Saturday and Saturday-to-Thursday weeks are all available, which matters for anything spanning the Gulf, Israel or South Asia.
