Setting up the Job Queue for Calendar Event Execution - Codeunit 2161

Does anyone know the purpose of CodeUnit 2161 (Calendar Event Execution) and how it should be properly set up in the Job Queue? We’re running BC14 on premise. I’m setting this up for a new company and noticed that in our existing company it is running, but the setup is odd. It is set up as a recurring job, yet no days are checked. It is not possible to set the job queue up this way through the BC client.
