Is there a short simple key sequence that will take you to the last 
entry in a date-tree and open that headline?  Slightly better would be a 
way to go to the last, and open the last N headlines.  It could be 
generalized into "go to end of current item and open last N items of 
whatever depth" when applied to other outline forms.

I know how to do this with tabs and cursor movement to walk down the 
tree opening headlines as needed.  This requires more work and paying 
attention.

I have not found a simple way to do this.  Does one exist?

Can't you just do something like this on the top-level headline for the
tree

C-c C-k C-c C-f M-7 C-c C-p

(where N=7 in this example)

That puts the cursor on the 7th-last heading (hope that makes sense)
It's not particularly short though...
  C-c C-k - show all siblings
  C-c C-f - go forward to next headline
  M-7 C-c C-p - go back to previous heading 7 times

or maybe

C-c C-f C-b C-c C-r

You should be able to build a local interactive function that takes a
prefix argument for N to get you where you want to be.

You can also use M-3 S-TAB to open show level 3 tasks and then navigate
the folded tree.

HTH,
Bernt

Hi Robert,

Not sure what you want to do after opening but I have some code that
extracts a time range out of a date tree.  Maybe you can reuse the
searching parts ...

Cheers,
Martin
