# NETWORKDAYS

Returns the number of workdays between a start date and an end date. Holidays can be deducted.

The functions whose names end with _ADD or _EXCEL2003 return the same results as the corresponding Microsoft Excel 2003 functions without the suffix. Use the functions without suffix to get results based on international standards.

### Syntax

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 recognised 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 - Preferences Tools - Options - 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.

### Examples

How many workdays fall between 2001-12-15 and 2002-01-15? The start date is located in C3 and the end date in D3. Cells F3 to J3 contain the following Christmas and New Year holidays: "2001-12-24", "2001-12-25", "2001-12-26", "2001-12-31", "2002-01-01".

=NETWORKDAYS(C3;D3;F3:J3) returns 17 workdays.

How many workdays fall between September 12nd and 25th in 2016 if only Mondays, Tuesdays and Wednesdays are considered as workdays?

=NETWORKDAYS(DATE(2016;9;12); DATE(2016;9;25); ; {1;0;0;0;1;1;1}) returns 6 workdays.
