My math is too fuzzy to decipher that. How about running this
every Sunday from cron?
DOM=`date --date=tomorrow +%d`
if [ "$DOM" -lt 15 -o "$DOM" -gt 21 ]
then exit
fi
..rest of script goes here...
I think that means today's %d must be between 14 and 20,
but the concept is handy because the string you hand
date= can be something like 'today + 2 weeks' if you
need to track things that fall into next month.
