Business Days Calculator
How many business days between two dates?
Weekends out, public holidays out, and the ones it removed listed by name — so you can see whether the calendar you picked is the one your contract means.
How this is worked out
- A holiday that falls on a weekend is not double-counted — it is listed separately, since it costs no working day.
- Substitute days are applied per calendar: the UK moves a weekend holiday to the next Monday, the US to the nearest weekday.
Questions people ask
The things that come up about business days calculators, answered plainly.
Which holidays are removed?
Whichever calendar you select. Every one is computed from its rule rather than looked up, so the answer is right for any year — including moving observances, like a holiday on a Saturday being taken on the Friday before.
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.
