Calendar View Settings - Don't show time


I don't use time in my calendar cards - it's like a work planning tool. How can I only show all day items - it seems weird to have the time section when thee is nothing there ?

I would also like to know how to do this. I do not use the times in calendar either. The closest I have come is to set the day start time to 11:30pm and end time to 12:00am.

That at least hides most of the times.
