How to get rid of one of the calendars?

[kriticar]

I would like to get rid of the left calendar application, and to use instead of it the right one as default calendar (attached picture) .
I am not able to uninstall the left one (dimmed).
What are my options considering that I don't have titanium backup?

is your device rooted?

Do not uninstall if not rooted. Just disable from settings / apps.

Disable is dimmed, that is why I asked.

So this is what I did:

1) Go ahead and install apk file under
2) When done, open Aurora Advanced Settings app (something like that)
3)Scroll down and choose "System Component Management"
4) Hit the check button for "Disable Desktop Calendar"

That's it, hope it helps! Feel free to ask any questions if needed..

I can install the Aurora, but I cannot open it.
