Cron jobs are scheduled tasks that are executed automatically at a specified time or interval. They are often used to automate repetitive or time-consuming tasks, such as checking for updates, or sending notifications. In the context of WordPress, cron jobs can be useful for improving the performance and reliability of your site. For example, you can use a cron job to schedule regular backups of your site or optimize your site’s performance by scheduling tasks such as deleting expired transients or clearing out old post revisions.

Overall, cron jobs can be a powerful tool for managing and maintaining a WordPress site, and they can save you time and effort in the long run.


What is WP-Cron?

WP-Cron is a powerful system used by WordPress to schedule tasks and execute them at regular intervals. It is designed to increase the flexibility and efficiency of the WordPress system by allowing the user to set up tasks to run at pre-determined times, ensuring that the tasks are always running when they should be. This system allows WordPress to keep up with the ever-changing needs of its users, as well as providing a convenient way to automate certain tasks that need to be done regularly. While the name (and the main idea) comes from UNIX cron, WordPress cron doesn’t work like that and uses intervals for task scheduling.

The default time intervals provided by WordPress are hourly, twice daily, daily, and weekly. Here, the time-based tasks depend on users visiting your site, meaning that WordPress cron will only execute if a user visits your website. In other words, WordPress cron is executed when the page loads up. Sometimes this isn’t that reliable, and that’s why many users prefer a server-level cron job over the WP-Cron job.
