Is your feature request related to a problem? Please describe.

I don't want to see every birthday from e.q. ex girlfriends and other archived contacts. But often, it's important, to have the adress (in a different addressbook).

Describe the solution you'd like

It would be nice, to choose the addressbook(s) for birthdays or to disable addressbook for the generated birthday calendar.
