Syntax

WORKDAY(StartDate; Days [; Holidays])

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

Days is the number of working days. Positive value for a result after the start date, negative value for a result before the start date.

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

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 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

What date came 17 working days after 1st December 2001? Enter the start date "2001-12-01" in C3 and the number of working days 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".

=WORKDAY(C3;D3;F3:J3) returns 2001-12-28. Format the serial date number as a date, for example in the format YYYY-MM-DD.
