## WORKDAY

結果是可格式化為日期的日期數字。接著，您會看到開始日期之後某天工作日的日期。

#### Syntax

WORKDAY(StartDate; Days; Holidays)

StartDate 是指開始計算的日期。若開始日期是工作日，則會在計算中包含該日。

Days 是指工作日天數。開始日期之後的結果為正值，開始日期之前的結果為負值。

Holidays 是指選用的假日清單。這些日子是非工作日。請輸入個別列出之假日的儲存格範圍。

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 - PreferencesTools - Options - LibreOffice Calc - Formula, button Details... in section "Detailed Calculation Settings", Conversion from text to number list box.

#### Example

2001 年 12 月 1 日過後 17 個工作日的日期為何？在 C3 輸入開始日期「2001-12-01」，並在 D3 中輸入工作日天數。儲存格 F3 到 J3 包含下列耶誕節與新年假日：「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.
