I am helping someone with an existing job tracking solution and they want to add a calendar to it. All they want is for their existing Due Date field to show up in a monthly calendar view with the name of the job that is due. Is that something that is easy to do with the free version? It seems like it has a lot more features than they are asking for.

Yep. It's easy to do in the Free Version. Just follow these instructions for pointing the calendar at the due date field in their file.

Another approach would be to relate the appointments table in our calendar to your job records. You can read more about this approach here:

Enjoy!
