From Apache OpenOffice Wiki
ISLEAPYEAR
Tests if a date is in a leap year.
This function is only available if the Analysis AddIn is installed.
Syntax:
ISLEAPYEAR(date)
- Returns 1 if date lies in a leap year, and 0 otherwise.
Example:
ISLEAPYEAR("2012-05-24")
- returns 1; 2012 is a leap year.
Issues:
- This function is not available in Excel. Try =MONTH(DATE(YEAR(date);2;29))=2 if you need compatibility with Excel.
