WEEKNUM

WEEKNUM는 내부 날짜 값에 대한 해당 연도의 주 번호를 계산합니다.

note

ISO 8601 표준은 월요일을 한 주의 시작으로 정해 놓았습니다. 새해가 한 주의 중간에서 시작할 경우 그 주가 어떤 해의 주로 간주될 지는, 7일 중에서 어떤 해에 속하는 날짜가 더 많은지에 따라 결정됩니다. 이 기준에 따르면, 한 해의 첫 주는 그 해의 1월 4일이 속하는 주가 됩니다.

note

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.


tip

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


=ISOWEEKNUM(DATE(1995;1;1)) returns 52. Week 1 starts on Monday, 1995-01-02.
