How to work with/access all the calendar events?

I’m using the calDav integration which is working OK - only problem is I need access to ALL of the calendar events in order to properly utilise the data in my calendar. It’s no good to just have access to one event at a time due to overlaps, whether it’s an all day event sat on top of (and therefore obscuring) a timed event or two timed events happening simultaneously.

Anyone successfully managed to access the data which is clearly there on the system as the calendar tab shows it beautifully!

thanks
