I am creating crontab entries and want to make sure I am doing them correctly.

So if I want to create a crontab entry that would run a script /etc/fixit.sh everyday at 3:09Am it would be

9 3 * * * /etc/fixit.sh

and on every sunday at 5:01PM it would be

1 17 * * 7 /etc/fixit.sh

and at 5:55AM on 2nd day of every month it would be

55 5 2 * * /etc/fixit.sh

Thanks in advance, I look forward to meeting new linux guru 's and learning alot!!
