How to use the Excel WORKDAY Function

The WORKDAY function figures out a date that represents the “nearest” working day N days in the past or future. WORKDAY can be used to calculate due dates, delivery dates, and other dates that should exclude non-working days.


If you are employing the WORKDAY in Excel, you will be required to input the following key terms.

  • start date – The date you want to begin with.
  • days – The range of work days ahead of or behind the start date.
  • holidays – [optional] Certain dates that should be seen as work-free. They can either be a range of cells having the dates you want to exempt from your calculations, or a range constant of the serial numbers depicting the dates.
  • return value- A serial number representing a particular date in Excel.

Let’s say you are working on a project containing a number of tasks. You are aware of the starting date and the number of workdays required to complete each of the tasks. You now want Excel to determine the date to complete each task. You cannot just include the start date and the total number of days because that would mean that weekends and holidays have been included to the required number of days for the tasks to get done. You will need to exclude weekends and holidays from the equation.
As soon as Excel determines the finish date, you would want a simple way to depict the project timeline. The end result should look like this.
