Cal question

This probably would be a cake walk for you, but i am having trouble with this.
I am trying to print every tuesday of the month from cal, and the FS default is space. There is one row that has few spaces at the beginning and so when i print $3, those spaces get ingnored and a different day gets printed. How can i ractify this problem? Thanks for your help.

without cut, and using gnu date
Code:
year=`date +%Y`
month=`date +%m`
for day in 1 2 3 4 5 6 7 8 9 10
do
    d=`date +%a -d "$year-$month-$day"`
    if [ "$d" == "Tue" ];then
        day=$day   
        break 
    fi
done
while [ "$day" -lt  31 ]
do
    echo $day
    day=$(( $day+7 ))
done

or
Code:
for day in `seq 31`
do
 d=`date +%a -d "$year-$month-$day"`
 if [ "$d" == "Tue" ];then
    echo $day    
 fi
don
