NETWORKDAYS(StartDate; EndDate [; [ Holidays ] [; Workdays ] ])

StartDate is the date from when the calculation is carried out. If the start date is a workday, the day is included in the calculation.

EndDate is the date up until when the calculation is carried out. If the end date is a workday, the day is included in the calculation.

Holidays is an optional list of holidays. These are non-working days. Enter a cell range in which the holidays are listed individually.

Workdays is an optional list of number values defining standard work week. This list starts by Sunday, workdays are indicated by zero and non-working days by non-zero value.


When entering dates as part of formulas, slashes or dashes used as date separators are interpreted as arithmetic operators. Therefore, dates entered in this format are not recognized as dates and result in erroneous calculations. To keep dates from being interpreted as parts of formulas use the DATE function, for example, DATE(1954;7;20), or place the date in quotation marks and use the ISO 8601 notation, for example, "1954-07-20". Avoid using locale dependent date formats such as "07/20/54", the calculation may produce errors if the document is loaded under different locale settings.


Unambiguous conversion is possible for ISO 8601 dates and times in their extended formats with separators. If a #VALUE! error occurs, then unselect Generate #VALUE! error in - LibreOffice Calc - Formula, button Details... in section "Detailed Calculation Settings", Conversion from text to number list box.


This function ignores any text or empty cell within a data range. If you suspect wrong results from this function, look for text in the data ranges. To highlight text contents in a data range, use the value highlighting feature.
