  • start_date
    : The starting date for the count. Workday recommends using a cell reference to specify the date instead of entering the date as text, to ensure reliable results.
  • end_date
    : The ending date for the count. Workday recommends using a cell reference to specify the date instead of entering the date as text, to ensure reliable results.
  • method
    : The method to use in the count. False or omitted = US (NASD) method; True = European method.
    • In the US method, if
      start_date
      is last day of a month, Workday sets it to the 30th of that month. If
      end_date
      is last day of month, then if
      start_date
      is the last day of month, Workday sets
      end_date
      to the 1st of the following month; otherwise, Workday sets
      end_date
      to the 30th of that month.
    • In the European method, if
      start_date
      is the last day of the month, Workday sets it to the 30th of that month. If
      end_date
      is the last day of the month, Workday sets it to the 30th of that month.
