Count only the days that actually count. Weekends are removed for you, and you can paste in your own public holidays.
Highlighted days are treated as non-working.

What Is It Used For?

Working out a delivery or shipping date given in business days.
Counting the working days in a month for payroll or capacity planning.
Checking a legal or contractual deadline expressed in working days.
Planning how much annual leave a trip will actually cost you.

Frequently Asked Questions
What counts as a working day?
By default, Monday to Friday, excluding any dates you list as holidays. You can change which weekdays count using the day buttons.
Are the start and end dates included?
Yes by default, since business deadlines usually count both endpoints. Untick the box if you only want the days in between.
Why do I have to enter holidays myself?
Public holidays vary by country, region and sometimes by employer. Entering your own list is the only way to get an accurate answer for your situation.
What happens if a holiday falls on a Saturday?
It is only counted once. The day is already excluded as a weekend, so listing it as a holiday does not reduce the total twice.
Can I use it for a four-day or six-day week?
Yes. Click the day buttons to mark exactly which days do not count as working days.
How many working days are there in a year?
Around 260 before holidays — 52 weeks of five days, give or take a day depending on which weekday the year begins on. Deducting typical public holidays leaves roughly 250 to 253 in most countries.
Does the calculator know my country holidays?
No, and deliberately so. Holiday calendars differ by country, by region and sometimes by employer, and a confidently wrong list is worse than no list at all. Pasting your own dates makes the result exact for your situation.
