Calendar That Shows Run Dates Not Due Dates

I am trying to build out a marketing calendar that shows duration of the run dates of the campaign item(s) such as banners or display ads, not due dates.
I know you can go to the Due Date Field and select a start and end date from there, but that still does not help in reporting on tasks that might be off track.

What am I missing?

Welcome, @Chris_Giggy,

I’ve read your post a couple of times, but I’m not clear exactly what you’re looking for. Could you go into more detail about the outcome you’re seeking? I’m not clear how duration would help you, or what you mean by “reporting” in the context of a request to see something on a calendar.

Does the Gantt view which actually has a Duration column help you?
