A cron job is a scheduled task used to automate the execution of scripts or commands at defined intervals—such as every minute, hour, day, or week. It is commonly used to handle repetitive tasks automatically, helping to save time and reduce the chance of human error.

Typical uses for cron jobs include automating database backups, sending email notifications, clearing temporary files, and performing routine system maintenance. When configured through tools like cPanel, cron jobs help ensure that important tasks are executed consistently and on time, improving the overall reliability and performance of your website.
