Question

I need help to count only business days (i.e excluding Saturday and Sunday ) between two dates in xslt 1.0

Answer 1

count only business days (i.e excluding Saturday and Sunday ) between two dates in xslt 1.0

If it can be assumed that the two given dates will not fall on Saturday or Sunday, you could use the method shown in the following example:

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="/">
    <output>
        <workdays>
            <xsl:call-template name="duration-in-workdays">
                <xsl:with-param name="start-date" select="'2015-04-02'" />
                <xsl:with-param name="end-date" select="'2015-04-08'" />
            </xsl:call-template>
        </workdays>
    </output>
</xsl:template> 

<xsl:template name="duration-in-workdays">
    <!-- assumes start-date and end-date are both workdays -->
    <xsl:param name="start-date"/>
    <xsl:param name="end-date"/>
    <xsl:variable name="start">
        <xsl:call-template name="JDN">
            <xsl:with-param name="date" select="$start-date" />
        </xsl:call-template>
    </xsl:variable>
    <xsl:variable name="end">
        <xsl:call-template name="JDN">
            <xsl:with-param name="date" select="$end-date" />
        </xsl:call-template>
    </xsl:variable>
    <xsl:variable name="start-weekday" select="($start + 1) mod 7" />
    <xsl:variable name="end-weekday" select="($end + 1) mod 7" />
    <xsl:variable name="weeks" select="floor(($end - $start) div 7)" />
    <xsl:variable name="days" select="($end - $start) mod 7" />

    <xsl:value-of select="5 * $weeks + $days - 2*($start-weekday > $end-weekday)"/>
</xsl:template> 

<xsl:template name="JDN">
    <xsl:param name="date"/>
    <xsl:variable name="year" select="substring($date, 1, 4)"/>
    <xsl:variable name="month" select="substring($date, 6, 2)"/>
    <xsl:variable name="day" select="substring($date, 9, 2)"/>
    <xsl:variable name="a" select="floor((14 - $month) div 12)"/>
    <xsl:variable name="y" select="$year + 4800 - $a"/>
    <xsl:variable name="m" select="$month + 12*$a - 3"/>
    <xsl:value-of select="$day + floor((153*$m + 2) div 5) + 365*$y + floor($y div 4) - floor($y div 100) + floor($y div 400) - 32045" />
</xsl:template> 

</xsl:stylesheet>

</xsl:stylesheet>

Caveat: not tested thoroughly.

<xsl:template match="/">
    <xsl:value-of select="this:WorkDayDifference(xs:date('2014-05-01'),xs:date('2014-05-12'))"/>
    

</xsl:template>

    <xsl:function name="this:WorkDayDifference">
        <xsl:param name="startDate" as="xs:date"/>
        <xsl:param name="endDate" as="xs:date"/>
        <xsl:variable name="endDateDay" select="this:day-of-week($endDate)"/>
        <xsl:variable name="days" select="days-from-duration($endDate - $startDate)"/>
        <xsl:variable name="dow1" select="this:day-of-week($startDate)"/>
        <xsl:variable name="dow2" select="this:day-of-week($endDate)"/>
        <xsl:variable name="weeks" select="xs:integer($days div 7)"/>
        <xsl:variable name="offset" select="if($dow2 ge $dow1) then if($endDateDay = 6 or $endDateDay = 0)then(-6)else(-5) else if($endDateDay = 6 or $endDateDay = 0)then(-1)else(0)"/>
        <xsl:variable name="wdays" select="sum((0,1,1,1,1,1,0,0,1,1,1,1,1,0)[position() ge $dow1 + 1 and position() le ($dow2 + 7)]) + $weeks * 5 + $offset + 1"/>
        <xsl:value-of select="number($wdays)"/>
    </xsl:function>
    
    <xsl:function name="this:day-of-week" as="xs:integer?" >
        <xsl:param name="date" as="xs:anyAtomicType?"/>
        <xsl:sequence select="if (empty($date)) then () else (xs:integer((xs:date($date) - xs:date('1901-01-06')) div xs:dayTimeDuration('P1D')) mod 7)"/>
    </xsl:function>
