Documentation/How Tos/Calc: ISLEAPYEAR function

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.
