Documentation/Calc Functions/NETWORKDAYS EXCEL2003
Date and Time
Calculates the net number of work or business days between two dates. Holidays (or other non-work days) can be specified and these are excluded from the count, together with the standard weekend days of Saturday and Sunday.
NETWORKDAYS_EXCEL2003 exists only for interoperability with legacy documents created with older versions of Microsoft Excel. In Calc, if you open an Excel 2003 (.xls) file that contains calls to the NETWORKDAYS function, those calls are converted to calls to the NETWORKDAYS_EXCEL2003 function. If you save a document from Calc in ODS (Open Document Format for Office Applications) or OOXML (Office Open XML) format, any calls to the NETWORKDAYS_EXCEL2003 function are converted to refer to the NETWORKDAYS function.
Because of the limited applicability of this function, fuller details are intentionally omitted from this wiki.
