How the business days calculator works
Count the working days between two dates, or find the date a number of working days after or before a start date. You choose which days are the weekend and can list holidays to skip.
The method
Business days = calendar days − weekend days − holidays on working days
Each day in the range is checked one by one, so any weekend and any list of holidays give an exact count.
Worked examples
- November 2 to November 30, 2026, both included: 29 calendar days, 8 weekend days, 21 business days. With November 26 as a holiday, 20.
- 10 business days after Friday, November 13, 2026 is Friday, November 27.
- With a Friday–Saturday weekend, November 2–30, 2026 also has 21 business days.
Frequently asked questions
Does the calculator know public holidays?
No. Public holidays differ between countries, regions and years, so rather than guess, the calculator lets you list the ones that apply to you. A holiday that falls on a weekend is not subtracted twice.
Is the start date counted?
When counting between two dates, the start date counts if it is a business day, and you choose whether the end date counts too. When adding business days, the start date is not counted: 1 business day after a Friday is the next Monday.
My weekend is not Saturday and Sunday. Can I change it?
Yes. Tap the days that are your weekend. In some countries the weekend is Friday and Saturday, and some people work six days a week.
How is this different from the Date Calculator?
The Date Calculator counts all days and Monday–Friday weekdays between dates. This one lets you choose the weekend, exclude your holidays and step forward or back by business days.
