why use EXSLT which are date extensions for XSLT1, when saxon8 has the
XPath2 date functions already?

This for example returns the first saturday of the current month.

$ saxon8 -it main saturday.xsl 
<?xml version="1.0" encoding="UTF-8"?>
today:  2007-01-30Z
1st of month   2007-01-01Z
1st day month   Monday
1st saturday of month : 2007-01-06Z

<xsl:stylesheet version="2.0" 

<xsl:template name="main">
today:  <xsl:value-of  select="current-date()"/>
<xsl:variable name="today" select="current-date()"/>
<xsl:variable name="fom" 
  select="current-date()- xs:dayTimeDuration(concat('P',day-from-date(current-date())-1,'DT0S'))"/>
1st of month   <xsl:value-of  select="$fom"/>
1st day month   <xsl:value-of  select="format-date($fom,'[F]')"/>
1st saturday of month : <xsl:value-of select="(for $d in  0 to 6
   $fom + xs:dayTimeDuration(concat('P',$d,'DT0S')))[format-date(.,'[F]')='Saturday']
