Function Package: date.leap-year.zip

boolean date:leap-year(string?)

Template Syntax

<xsl:call-template name="date:leap-year">
   <xsl:with-param name="date-time" select="string" />?
</xsl:call-template>

The date:leap-year function returns true if the year given in a date is a leap year. If no argument is given, then the current local date/time, as returned by date:date-time is used as a default argument.

The date/time string specified as the first argument must be a right-truncated string in the format defined as the lexical representation of xs:dateTime in one of the formats defined in [XML Schema Part 2: Datatypes]. The permitted formats are as follows:

xs:dateTime (CCYY-MM-DDThh:mm:ss)
xs:date (CCYY-MM-DD)
xs:gYearMonth (CCYY-MM)
xs:gYear (CCYY)

If the date/time string is not in one of these formats, then NaN is returned.
