The functions whose names end with _ADD or _EXCEL2003 return the same results as the corresponding Microsoft Excel 2003 functions without the suffix. Use the functions without suffix to get results based on international standards.

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, 2000-01-01 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.

## 0일에 대한 날짜 기준

날짜는 0일부터의 오프셋으로 계산됩니다. 0일을 다음 중 하나로 설정할 수 있습니다.

날짜 기준 | @@@사용
--- | ---
'1899-12-30' | (기본값)
'1900-01-01' | (이전 StarCalc 1.0에서 사용됨)
'1904-01-01' | (Apple 소프트웨어에서 사용됨)

날짜 기반을 선택하려면 LibreOffice - 기본 설정도구 - 기본 설정 - LibreOffice Calc - 계산을 선택하십시오.

다른 스프레드시트 간에 날짜 값이 들어 있는 셀을 복사하여 붙여 넣을 경우 두 스프레드시트 문서를 날짜 기준으로 설정해야 합니다. 날짜 기준이 다르면 표시되는 날짜 값이 달라집니다.!

## 두 자리수 연도

In LibreOffice - Preferences 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.

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.

Time zone information is not used in Date and Time functions and cells.
