Calculate Workdays Between Dates Using NETWORKDAYS in Excel

In this tutorial, we explore the NETWORKDAYS function in Excel, which allows users to determine the number of active workdays between two given dates, excluding weekends and optionally considering holidays. The video demonstrates how to set up the function with a start date and an end date and explains how to incorporate holiday lists to get an accurate calculation of workdays. The video also touches on the limitations of the default weekend settings in the NETWORKDAYS function and hints at the upcoming exploration of the NETWORKDAYS.INTL function to customize the definition of weekends.
