Using MS Excel's Networkdays Function

By Deborah J. Sparks


"How can I figure out the number of working days, excluding weekend and holidays, between two dates?"


Use the NETWORKDAYS function:

Trying to calculate vacation entitlement or determine the number of working days for a project that has a set end date? Try the NETWORKDAYS function. Here are the components:

  • The start date
  • The end date
  • Holidays (optional)

You can key in the dates and number of statutory holidays, or simply refer to cell addresses that contain this information.

Here is the formula used for the worksheet below:


Note: If this function is not available, and returns the #NAME? error, install and load the Analysis ToolPak add-in from the Tools menu.

There are many other date formulas and functions, including DAYS360, in Excel that will help you get the results you need.
