I would say that running the script every day, and letting it decide
if Today is the right day, is a good approach.

Manually creating a list of dates seems to me to be asking for
trouble. A modern "date" command (with a "v" option) offers many
helpful features.
I don't have an HP-UX system running at the moment, but the following
method seems to work on a Mac:
#!/bin/sh
# Start of test loop.
ofs=1 # Offset (months), for testing.
while test ${ofs} -lt 24 ; do
# Actual last-workday-of-month calculation.
dow=8 # "%u": 1=Mon - 7=Sun.
back=0 # Days back from end-of-month.
while test ${dow} -gt 5 ; do # Want day-of-week Mon-Fri (1-5).
back=` expr ${back} + 1 ` # Increment back step.
date -v1d -v+${ofs}m -v-${back}d # End of this month less "back" days.
# (If "ofs" == 1.)
dow=` date -v1d -v+${ofs}m -v-${back}d +%u ` # Day of week.
echo "dow = ${dow}"
done
# Date strings for comparison with Today.
lwd_dat=` date -v1d -v+${ofs}m -v-${back}d +%G-%m-%d `
tod_dat=` date +%G-%m-%d `
echo ${lwd_dat}
### echo ${tod_dat}
# End of test loop.
echo ''
ofs=` expr $ofs + 1 ` # Increment offset months.
done
