## DATEVALUE

Tagastab jutumärkides oleva tekstiga väljendatud kuupäeva seerianumbri.

Programmisisene kuupäevanumber tagastatakse arvuna. Arvu määrab ära kuupäevasüsteem, mida LibreOffice kuupäevade arvutamiseks kasutab.

Kui tekstistring sisaldab ka kellaajaväärtust, tagastab DATEVALUE üksnes teisenduse täisarvulise osa.

This function is part of the Open Document Format for Office Applications (OpenDocument) standard Version 1.2. (ISO/IEC 26300:2-2015)

#### Süntaks

DATEVALUE("Tekst")

Tekst on kehtiv kuupäevaavaldis, mis tuleb sisestada jutumärkides.

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.

#### Näide

=DATEVALUE("1954-07-20") yields 19925.
