You can type command "crontab -e" in terminal, which will open crontab file in vi editor.

In that file, you can use following line to run your job

1) To run job everyday at 12:20 AM
20 0 * * * "command or script to be executed"

2) To run job everyday at 5:20 AM
20 5 * * * "command or script to be executed"

Please check your syntax against the reference document, your cron job is set to run at 6 AM and 1 PM every day. The hours run 0-23 not 1-24, minutes run 0-59 instead of 1-60 and so on.

None of these will allow for a special backup time. These run at a preset time they are just blank files.
