## DATAE

El resultat és una data que és un nombre de mesos abans de la data d'inici. Només es tenen en compte els mesos; els dies no s'utilitzen per al càlcul.

### Syntax

DATAE(DataInicial; Mesos)

DataInicial és una data.

Mesos és el nombre de mesos abans (negatiu) o després (positiu) de la data d'inici.

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

### Example

Quina és la data un mes abans del 31/03/2001?

=DATAE("2001-03-31";-1) retorna el número de sèrie 36950. En format de data, això és 2001-03-31.
