Template Syntax

<xsl:call-template name="date:day-in-week">
   <xsl:with-param name="date-time" select="string" />?
</xsl:call-template>

The date:day-in-week function returns the day of the week given in a date as a number. If no argument is given, then the current local date/time, as returned by date:date-time is used the default argument.

The date/time string specified as the argument is 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)

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

The numbering of days of the week starts at 1 for Sunday, 2 for Monday and so on up to 7 for Saturday.
