Business Days Calculator

Count the business days between two dates online, already discounting weekends and national holidays.

Updated: July 2026

What is the Business Days Calculator

If you work in HR, Logistics, the Financial Sector or Law (law), you know that calculating deadlines by hand is a recipe for disaster. But worse than calculating by hand is using outdated calculators on the internet.

We developed the most modern and reliable Business Days engine in Brazil, built with three pillars that other tools ignore:

  1. Updated with Law 14,759/23: Did you know that National Zombie and Black Consciousness Day (November 20) became a mandatory National Holiday at the end of 2023? Almost no internet tool has updated this calculation, causing you to miss deadlines at the end of the year. We've already included it!
  2. Mobile Holidays Engine: In addition to fixed holidays, our algorithm uses Computus computational mathematics to find the exact day of Easter in any year you search. With this, we automatically discount Good Friday, Carnival and Corpus Christi in a dynamic way.
  3. Procedural Deadline Rule (CPC) and HR: The Civil Procedure Code (CPC) and most contracts say: "the start day is excluded, and the expiry day is included". We put a gigantic button on the screen so you can turn this rule on and off with one click.

How to use our Deadlines Dashboard?

Using the tool is simple. Just enter the start date and the end date. Immediately the screen will show our HR Dashboard, displaying:

  • The total number of calendar days;
  • The total number of Weekends that were deducted;
  • The total number of National Holidays that fell in the middle of working days and were discounted.

And to ensure maximum transparency for you to present the count to your boss or in court proceedings, we display a Found Holidays Table, listing the name and exact date of each holiday that our robot subtracted from the count!

Perguntas frequentes

What are business days?

Business days are normal business days, that is, from Monday to Friday, excluding holidays. Saturdays, Sundays and national holidays are not considered business days. They serve as the basis for contract deadlines, deliveries and payments.

Does the calculator take holidays into account?

Yes. The tool automatically discounts national holidays, both fixed ones (like Christmas) and movable ones, which change dates every year because they depend on Easter, like Carnival and Corpus Christi. State and municipal holidays are not included in the account.

What is the difference between business days and calendar days?

Calendar days count all days on the calendar, including Saturdays, Sundays and holidays. Business days only include working days. Therefore, a period of 10 working days usually ends well after 10 calendar days.

Does the starting day count?

This depends on your term rule, as each contract or rule may define it differently. The calculator counts the working days of the period informed, but it is worth checking whether, in your case, the first day should be included or not.

Do I need to pay or register to use it?

No. The Business Days Calculator is completely free, works directly in the browser and does not require registration. You can do as many calculations as you want, whenever you need.
