What is Cron Jobs
Cron is a time-based job which are scheduled in Unix or Unix-like computer operating systems. You can use Cron to schedule jobs, i.e. to execute different commands or shell commands scripts at specified times, dates, or intervals.
This allows you, to automate system maintenance or management tasks like, to download files from the internet, or to send emails on a regular basis. It is a daemon, i.e. a background process that always runs on the server. The tasks Cron is supposed to perform are called Cron Jobs.

To the extent that you really need to run cron jobs at intervals of less than 15 minutes, we recommend that you turn to VPS server -type services .
Note! The Hosting servers benefit from monitoring systems so that if you configure the cron job at an interval of less than 15 minutes, it will automatically be changed to 17 minutes or 18 minutes as per systems resources. By setting an interval of 15 minutes, it will be kept.
