[Solved] crontab issue "day of week"

Is there an issue with running a cron entry like the below entries?

0 2 21 12 2 cd /usr/local/bin;./cksecurity.sh -f /home/theninja/security.dat21

I wanted this to run on Tues at 2am, which it did successfully, however I also had the following entry to run next tuesday that also ran on 12/21.

0 3 28 12 2 cd /usr/local/bin;./cksecurity.sh -f /home/theninja/security.dat28

Is there an issue with the weekday field taking precedence or ignoring the day_of_month field?

Thanks
Dave

Have a look at post #3 in this thread

If you want cron to run every Tuesday and 2AM

 
0 2 * * 2 cd /usr/local/bin;./cksecurity.sh -f /home/theninja/security.dat$(date '+%d')

A quick read of the man page answered my question......

0 0 1,15 * 1 command

   would run command on the first and fifteenth days of each month, as well as every Monday. To specify days by only one field, the
   other field should contain an * .

Thanks for the replies though.
