Try and adapt the following script (based on cal command output) :

Code:

day=${1:-$(date +%e)}
month=${2:-$(date +%m)}
year=${3:-$(date +%Y)}

#
# Determine week in the month
#

wmonth=${month}
wyear=${year}

cal ${wmonth} ${wyear} | \
awk -v day="$day" '
        /^[[:digit:][:space:]]*$/ && NF>0 {
           if (substr($0, 1, 2) != "  ") wm += 1;
              for (i=1; i<=NF; i++) {
                if ($i+0 == day+0) {
                    print wm;
                    exit;
                 }
              }
           }
    ' | read week

#
# Determine week in previous month
#

if [ -z "${week}" ]
then

   # Previous month/year

   (( wmonth = month - 1 ))
   if (( wmonth == 0 ))
   then
      wmonth=12
      (( wyear -= 1))
   fi

   # Determine week

   cal ${wmonth} ${wyear} | \
   awk '
        /^[[:digit:][:space:]]*$/ && NF>0 {
           if (substr($0, 1, 2) != "  ") wm += 1;
        } 
        END { print wm }
    ' | read week
fi

#
# Display result
#

echo "Date = ${day}-${month}-${year}, Week.Month.Year = ${week}.${wmonth}.${wyear}"

Examples:

Code:

$ wm.ksh
Date =  7-11-2006, Week.Month.Year = 1.11.2006

$ wm.ksh 1 11
Date = 1-11-2006, Week.Month.Year = 5.10.2006

	      ini_set('intl.default_locale', 'es_ES');

	      $cal = IntlCalendar::createInstance();
	      $cal->set(2013, 5 /* June */, 30); // A Sunday

	      var_dump($cal->getFirstDayOfWeek()); // 2 (Monday)

	      echo IntlDateFormatter::formatObject($cal, <<<EOD
	      week of month    : 'W'
	      week of year     : 'ww
	      EOD
