IBM Planning Analytics Tips & Tricks: Excel’s NETWORKDAYS Function

January 26, 2021

Have you ever wanted to define the number of working days between two calendar dates? Do you define “working days” simply as non-weekend days or do you also include holidays? Did you know that you can calculate this information using Excel’s NETWORKDAYS function?

The NETWORKDAYS function is used to determine the number of whole working days between start_date and end_date. Working days are defined as the exclusion of weekends, which in essence computes the number of Mondays through Fridays. The function also includes an optional parameter to exclude holidays and any other specific non-working days.

The syntax of the function is:

NETWORKDAYS (start_date, end_date, [holidays])

Start_date: This is required
End_date: This is required
Holidays: This is optional
- This consists of a range of one or more dates to be excluded from the calendar. The list entails a range of cells that contains the dates.

Note: All dates are entered in date format or in serial number format

This information can be used to help calculate any/all of the following pieces of your model:

Benefit accruals and eligibility
Ratios such as “Revenue per day” or “Units per day”
Days remaining for end-of-service dates
Anything else that requires the number of days within the formula
