The third friday is always between days 15 and 21 inclusive of the month .
You can made the test like that :

Code:

day_of_week=$(date +%w)  # (0..6); 0 is Sunday, 5 is Friday
day_of_month=$(date +%e) # space padded
if [ ${day_of_week} -eq 5 -a ${day_of_month} -ge 15 -a ${day_of_month} -le 21 ]
then
   echo "third Friday "
fi
