How many business days are there between two dates?

Select the two dates and the calculator counts every day in the range that is not a weekend or a public holiday. It also shows the total calendar days, how many of those were weekend days, and which holidays fell inside the range, so you can check the number rather than just trust it.

What counts as a business day?

By default a business day is Monday to Friday, excluding any public holiday you have enabled. If your working week runs Sunday to Thursday, switch the weekend setting to Friday–Saturday; if you work six days, choose Sunday only. The count updates immediately.

What date is 10 business days from today?

Switch to the add mode, leave the start date as today, and enter 10. The calculator steps forward day by day, skipping weekends and holidays, and shows the resulting date with its weekday. Use subtract to work backwards from a fixed deadline to the date you need to start.

Does the result include the start and end date?

The end date is always included. The start date is controlled by the "count the start date" toggle, which is on by default — that matches phrasing like "you have five working days from today". Turn it off for contracts that count from the day after the trigger date.

Which public holidays does it know about?

The presets cover the United States, United Kingdom, Germany and France. Each one is derived from the published rule — a fixed date, an n-th weekday of the month, or an offset from Easter — so it stays correct for any year instead of relying on a table that goes stale. Countries whose holidays are announced annually by decree, including China's public holidays and its make-up working days, cannot be derived that way, so add those dates in the custom field.

Is this the same as the NETWORKDAYS function in Excel?

The between mode does the same job as NETWORKDAYS, and the add mode matches WORKDAY. The difference is that you can change the weekend pattern and paste holidays in without building a separate range in a spreadsheet.

About the Business Days Calculator

This business days calculator answers the two questions that come up every time a deadline is set: how many working days between two dates, and what date falls a given number of business days from today. It skips weekends and public holidays, so a ten-business-day turnaround lands on the date your team will actually hit rather than the one a plain calendar suggests. Weekends are configurable — Saturday–Sunday, Friday–Saturday, or Sunday only — and you can layer on a national holiday preset plus any company closure days of your own. Every calculation runs locally in your browser; no dates are uploaded.
