The question is not clear.  E.g.:

   "I would like the function to work without actually switching to the
   calendar window -- i.e., it should work even when the buffer is buried."

While we clearly can't select the calendar window if the calendar is
not displayed, I don't see why that would make it undesirable to
temporarily select that window when it does exist.  E.g.

   (with-selected-window (or (get-buffer-window (current-buffer) 0)
                             (selected-window))
     (calendar-cursor-to-visible-date date))

Of course, if there are various windows displaying that buffer, things
are more interesting.

Those work just fine (although they don't quite do what you think they do).

Here I lost you again.  calendar-cursor-to-visible-date works inside the
calendar buffer, so you can't use it without switching to the
*Calendar* buffer.  But that's unrelated to whether or not you select
the corresponding window (if any).

Happy Holidays !!!

Here is the thread on stackoverflow that provides a working example of the problem, and a working solution:

http://stackoverflow.com/questions/20776564/how-to-use-calendar-cursor-to-visible-date-without-switching-to-calendar

Without adding `set-window-point` to the function `calendar-cursor-to-visible-date`, functions like `with-current-buffer` and `set-buffer` do not work properly.

From another window, it should be possible to use `calendar-cursor-to-visible-date` without actually switching to that "*Calendar*" buffer.

Thanks,

Keith
