Cron Tab
Posted by TMP on 12th April 2008
Cron can appear to be challenging at first, but with the proper help, you will find it easy and very helpful to automate tasks on your website.
Cron is simply a way to run any program/script on your web hosted account once a day, once a week, once a month, every Tuesday and Thursday, etc.
It is helpful in automatically performing web site maintenance, automating scripts that generate new sales/coupons/etc. It can even help establish a back routine for your web site.
Cron is composed of five fields. The following chart details each field.
| Minute | Hour | Day of Month | Month | Day of Week | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
etc. |

Common examples include…
| minute | hour | day of month | month | day of week | |
| To perform a daily task at 2 am | 0 | 2 | * | * | * |
| To perform a weekly task on Sunday at 2 am | 0 | 2 | * | * | 0 |
| To perform a monthly task on the 1st of each month at 2 am | 0 | 2 | 1 | * | * |
| To perform a task each Tuesday AND Friday at 2 am | 0 | 2 | * | * | 2,5 |
The following chart indicates what each number or symbol represent.
Please note:
- Set the cron to perform the task ONLY as frequently as you expect you need the task to be performed.
- Do NOT set the cron to perform something everyday and that only needs to be done once a month or every other week. This wastes valuable CPU time for your website and for others.
