Show availability in Calendar (instead of occupation)

[fery]

Hi,

I would like to reverse the Calendar view from occupation to availability.

What do I mean by that? In month view I have ‘marked’ days when I am busy (have meetings, phone calls…), but instead of that I want to see days, when I have nothing, I am available.

I would like to compute that in days, not in hours. Is there any way how to proceed?

Thanks.
