WEEKNUM racuna broj sedmice u godini za interni datum.

Note Icon

Internacionalni Standard ISO 8601 je proglasio Ponedjeljak prvim danom sedmice. Sedmica koja je dijelom u jednom godini a dijelom u drugoj je dodijeljena godini u kojoj vecina njenih dana leži. To znaci da je prva sedmica bilo koje godine ona sedmica koja sadrži 4. Januar.


This function is available since LibreOffice 5.1



Broj je interni datum.


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