Hi Bruce,

I modified your code as follow to be able to insert a datetree entry
correctly being anywhere in an existing datetree. I also added the
possibility of having a prefix argument to prompt for the date. It works
for me, but I don't know if this is the most elegant way to obtain what
I want. Comments are welcome.


;; look for datetree root
(defun dnn-org-datetree-root ()
  (let ((re
"^\\([12][0-9]\\{3\\}\\)\\(-\\([01][0-9]\\)\\(-\\([0123][0-9]\\)\\)?\\)?
\\w+$"))
    (while (string-match re (org-get-heading))
      (org-up-heading-safe))
    (org-up-heading-safe)))

;; add a datetree entry
(defun dnn-org-datetree-find-create (arg)
  (interactive "P")
  (let ((d (calendar-gregorian-from-absolute
            (if arg (time-to-days (org-read-date nil t)) (org-today)))))
    (dnn-org-datetree-root)
    (org-datetree-find-date-create d 'subtree-at-point)))


Cheers,
Daniele
