(from `man crontab`), the 3rd, 4th & 5th fields are:
monthday       The day of the month, 1-31
month          The month of the year, 1-12
weekday        The day of the week, 0-6, 0=Sunday

* is a wildcard, so ths script will execute every day of the month, every month of the year, every day of the week.

Remember to include the full path to the script, and ensure it sets up all the environment variables it needs, as .profile won't get executed..
