Cron job enables to run a set of commands at scheduled date and time repeatedly. Fortunately, Magento 2 store owners can use this functionality in the store! However, before making any changes to your live site, it’s essential to set up a staging environment in Magento 2. This allows you to test any updates or changes without risking disruption to your live site.

Moreover, there are tasks that need to be done later in order to avoid system overload, or simply due to the requirement of condition fulfillment. But if want some of the tasks to be done in decided hours you need to Dynamically Schedule Cron Job in Magento 2 System Configuration.
