The financial day count basis rules are explained further on the Wikipedia Day Count Convention page

Note: The date arguments should be entered into the function as either:

  • References to cells containing dates, or
  • Dates returned from formulas

If you attempt to input these date arguments as text, Excel may misinterpret them, due to different date systems, or date interpretation settings.

Warning: Although you can input the date arguments as date serial numbers, this is not recommended as date serial numbering does vary across different computer systems.
