Note.png Les funcions el nom de les quals acaba amb _ADD o _EXCEL 2003 retornen els mateixos resultats que les funcions corresponents del Microsoft Excel 2003 sense el sufix. Utilitzeu les funcions sense sufix per obtenir resultats basats en els estàndards internacionals.

LibreOffice internally handles a date/time value as a numerical value. If you assign the numbering format "Number" to a date or time value, it is converted to a number. For example, 01/01/2000 12:00 PM, converts to 36526.5. The value preceding the decimal point corresponds to the date; the value following the decimal point corresponds to the time. If you do not want to see this type of numerical date or time representation, change the number format (date or time) accordingly. To do this, select the cell containing the date or time value, call its context menu and select Format Cells. The Numbers tab page contains the functions for defining the number format.

Base de dates per al dia zero

Les dates es calculen a partir d'un dia zero de referència. Podeu configurar el dia zero de les maneres següents:

Base de dates Utilitza
'30/12/1899' (per defecte)
'01/01/1900' (s'utilitzava a l'StarCalc 1.0)
'01/01/1904' (s'utilitza a programari d'Apple)

Trieu Eines ▸ Opcions' ▸ LibreOffice Calc ▸ Calcula' per a seleccionar la base de dates.

Warning.png Quan copieu i enganxeu cel·les que contenen valors de dates entre diferents fulls de càlcul, ambdós documents de full de càlcul han d'estar definits amb la mateixa base de dates. Si les bases de dates són diferents, els valors de data que es mostren canviaran.

Anys de dues xifres

In Tools - Options' - LibreOffice - General' you find the area Year (two digits). This sets the period for which two-digit information applies. Note that changes made here have an effect on some of the following functions.

Note.png 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.
