How Long is One Business Day?

One business day means a 24-hour period within the standard workweek, from Monday to Friday. However, it also refers to a portion of a day that is comprised of 8 hours when businesses are operating. The time is usually 9 to 5, depending on the industry and location.

  • For example, if you placed an order on Thursday and it is to be delivered on the next business day, that would be Friday.
  • If you place an order on Friday, the next business day will be Monday, as Saturday and Sunday are weekends and are excluded from the list of business days.

Business Days vs Calendar Days

Now that you know what is considered a business day, it is important to differentiate it from the calendar days. Calendar days are basically all seven days of the week. It also includes all public holidays.

For instance, if someone tells you the return policy is 7 calendar days, it means that you only have one week, including Saturday and Sunday.

If the return policy is 7 business days, it might stretch up to two weeks in real time.

Business Days Vs Working Days

You must have seen business days and working days used interchangeably. However, sometimes they mean different things.

A workday is similar to a business day in the sense that employees are expected to work 8 hours. However, in some industries, employees have to work overtime and they get paid for that.

  • Business days are Monday to Friday in an office or financial setting.
  • Working days can include weekends, depending on the industry. For example, retail, hospitals, and restaurants do not close on weekends either.
  • Business days are the same across different sectors and are mostly used in corporate settings, while working days are more job-specific.

How to Calculate Business Days

When you are counting the business days, you do not count the day an event or contract happened. You start counting from the next day.

For example, you placed an order on a Monday and the delivery takes three business days, you should count from Tuesday as that will be considered the first business day. You also skip weekends and public holidays while counting.

Here is how you can calculate business days.

  • 1 Business Day: From Monday to Tuesday, or from Friday to the following Monday (excluding the weekend).
  • 2 Business Days: From Tuesday to Thursday, or from Friday to the following Tuesday.
  • 3 Business Days: From Wednesday to the next Monday or from Friday to the following Wednesday.
  • 5 Business Days: From Monday to the next Monday or from Thursday to the next Thursday.

Business Day in Contracts

The definition of a business day in a contract depends on the laws of a particular jurisdiction. The business days should be explained clearly in the contract to make it legally enforceable.
