Count the business days between two dates, or find where a deadline lands. Pick a country and its national holidays come out of the count.
Business days
National holidays only — state and regional ones are not included.
Five sevenths of a period is a reasonable estimate and a poor answer. Where the weekend falls inside the range changes the count, and a holiday on a Tuesday removes a working day that the division never sees. Thirty calendar days can hold twenty-two business days or nineteen, depending on the month and the country.
So this page counts day by day instead of estimating. It also shows the calendar days, the weekend days and the holidays separately, so you can see where the difference came from instead of accepting a number on its own.
The second mode answers the other half of the question: given a fifteen-working-day deadline, what date is that? Adding twenty-one calendar days is wrong whenever a holiday falls inside the window — which, in most countries, is most months.
That is your choice, and the toggle above shows which convention is in use — it changes the answer by exactly one day. Monday to Friday is five business days when both ends count, and four when the start date does not. Legal and contractual deadlines usually start counting the next day; "how many business days are in this month" counts both ends.
National holidays only, for the country you pick. State, provincial and local holidays are left out, because covering some and not others would give a wrong answer that looks precise. Family Day in Canada and the Melbourne Cup in Victoria are the kind of date that applies to part of a country, not all of it.
In the United Kingdom, the United States, Canada and Australia the day off moves to the next weekday, and the calculator follows. When Christmas and Boxing Day both fall on a weekend, the second one shifts to Tuesday, and the count handles that. In Brazil, Spain and Portugal the holiday is simply lost — there is no substitute day.
Yes. Enter a negative number of business days in the second mode and you get the date that many business days earlier — useful for working out when to start a task that has a fixed deadline.
