This information comes from 
"https://help.ubuntu.com/community/CronHowto"\\ 
\\ 
To edit the cron job list:
\\ 
    crontab -e (don't sudo, or you will change root cron, not your user cron)
\\ 
Then add your job, which has the format:
\\ 
Each line has five time-and-date fields, followed by a command, followed by a newline character ('\n'). The fields are separated by spaces. The five time-and-date fields cannot contain spaces. The five time-and-date fields are as follows: minute (0-59), hour (0-23, 0 = midnight), day (1-31), month (1-12), weekday (0-6, 0 = Sunday). 
\\ 
    01 04 1 1 1 /usr/bin/somedirectory/somecommand\\ 
\\ 
The above example will run /usr/bin/somedirectory/somecommand at 4:01am on January 1st plus every Monday in January. \\ 
\\ 
An asterisk (*) can be used so that every instance (every hour, every weekday, every month, etc.) of a time period is used. \\
