### 構文

DAYS360(Date1; Date2[; Type])

日付 2 が 日付 1 より前の場合、この関数は負の数を返します。

オプションのパラメータ タイプ では、計算方法を指定します。タイプに 0 を指定、または空白のままにした場合は、アメリカ式 (NASD、National Association of Securities Dealers, Inc.) が適用されます。タイプに 0 以外を指定した場合は、ヨーロッパ式が適用されます。

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.

### 例

=DAYS360("2000-01-01";NOW()) returns the number of interest days from January 1, 2000 until today.
