What is Scheduled Apex?

Scheduled apex or schedulable apex is all about running a piece of apex code at a specific time over a set period of time. Schedule apex is a Salesforce class that runs at regular intervals. To schedule an apex class, we must implement the Schedulable interface. If you want to run a piece of code on the first of every month or on a daily basis, you can use it to make your life easier when you have to redeploy/change this code. Apex scheduler runs in system mode, which means that whether the user has permission to execute the class or not, the class can be executed.

Every 10 minutes, a new scheduled apex job is added, and it's a great time to start a career as a Salesforce Developer. You can also access scheduled batch apex from the developer console with the proper code and approach.
