In this session, we delve into the WORKDAY function in Excel. This powerful function allows you to calculate a specific date after a given number of working days. Unlike the WEEKDAY function, the WORKDAY function considers only the active working days between two dates, excluding weekends and holidays. By using this function, you can accurately determine future dates based on your work schedule and any holidays you may have. We will also touch upon the nuances of different countries' workweek standards and provide examples to ensure a clear understanding of the function.

What will you learn

  • How the WORKDAY function differs from the WEEKDAY function
  • The syntax of the WORKDAY function in Excel
  • Calculating a future date by considering only working days
  • Incorporating holiday lists into the WORKDAY function

Takeaway notes

  • The WORKDAY function helps in calculating a specific date considering only working days.
  • Syntax: =WORKDAY(start_date, days, [holidays])
  • start_date: The starting date.
  • days: The number of working days to add.
  • [holidays] (optional): A range of dates to consider as non-working days.
  • The function excludes weekends (usually Saturdays and Sundays).
  • You can customize holidays by including them in the function's holiday argument.
  • The WORKDAY function does not count the start date as a workday.
  • In some regions, weekends may differ (e.g., Fridays and Saturdays). This will be covered in the next session with the WORKDAY.INTL function.
