Okay, sure, they're broken.  The current way isn't as smart as the older way
(and by the way [wink], thanks for the history lesson, Randal).  But it is
still easy enough to do by having the crontab line use the date command inside
an if.  It's "inelegant" and harder to read, but big deal, the general answer
does exist:

52 8 * * 1 if [ `date +\%d` -ge 21 -a `date +\%d` -le 27 ] ; then echo "Subject: green RECYCLE out Tuesday morn\n" | smail opmgr ofcasst >/dev/null ; fi
