Use of this command in cron job

[balaji2u]

Im analysing a script thats used for cron job and i get a clear view about it.
but the author of the script provided a unix command to make an automatic execution of the script.i know this can be down using the standard cron job manager in cpanel.
but i want to know the individual use of the numbers(1-5-2-*-*-* as in below command) and what it represents?


15 2 * * * /usr/local/bin/php /home/youraccount/fullbackup.php
he said this command will make the script to run on
every night at 2:15 a.m
pls explain it to me .
