## DAYS360

根據利息計算中使用的一年 360 天傳回兩個日期之間的差異值。

### Syntax

DAYS360("Date1"; "Date2"; Type)

若 Date2 早於 Date1，則函式會傳回負數。

選擇性的參數 type 決定了差異型態的類型。如果 type = 0 或者是缺少參數，則會使用 US 方式 (NASD, National Association of Securities Dealers, Inc.)。如果 type <> 0，則會使用歐洲方式。

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

### Example

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