You have two problems: Nov 15 is not a Saturday every year and you will have to test the year either in your script or in the crontab line:
Assume you want 2015:
crontab example:

This is not a good use of crontab. I suspect you want to run this thing the third Saturday of every November, not just once every 5-7 years. IF you need to run it JUST ONCE, the use at:
You should refer to your man page for the at command, because some varieties of at use slightly different syntax. I think HP's at is one of them.

CRONTAB(1) General Commands Manual CRONTAB(1)NAME
crontab - maintain crontab files for individual users (V3)
SYNOPSIS
crontab [ -u user ] file
crontab [ -u user ] { -l | -r | -e }
DESCRIPTION
Crontab is the program used to install, deinstall or list the tables used to drive the cron(8) daemon in Vixie Cron. Each user can have
their own crontab, and though these are files in /var, they are not intended to be edited directly.
If the allow file exists, then you must be listed therein in order to be allowed to use this command. If the allow file does not exist but
the deny file does exist, then you must not be listed in the deny file in order to use this command. If neither of these files exists,
then depending on site-dependent configuration parameters, only the super user will be allowed to use this command, or all users will be
able to use this command.
If the -u option is given, it specifies the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines
"your" crontab, i.e., the crontab of the person executing the command. Note that su(8) can confuse crontab and that if you are running
inside of su(8) you should always use the -u option for safety's sake.
The first form of this command is used to install a new crontab from some named file or standard input if the pseudo-filename ``-'' is
given.
The -l option causes the current crontab to be displayed on standard output.
The -r option causes the current crontab to be removed.
The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables. After you exit
from the editor, the modified crontab will be installed automatically.

/etc/cron.allow
/etc/cron.deny
STANDARDS
The crontab command conforms to IEEE Std1003.2-1992 (``POSIX''). This new command syntax differs from previous versions of Vixie Cron, as
well as from the classic SVR3 syntax.
DIAGNOSTICS
A fairly informative usage message appears if you run it with a bad command line.
