Hi,

I've always found the DATE header to be kind of useless, as it only indicates
the creation date of the file.

For me, it would be better if it would be the last edit date as it is the case
with the Emacs time-stamp.

Here a proposition to make this automagic:

--8<---------------cut here---------------start------------->8---
(add-hook 'org-mode-hook
         (lambda ()
(set (make-local-variable 'time-stamp-format) "%:y-%02m- %02d") (set (make-local-variable 'time-stamp-start) "^#\\+DATE: +")
           (set (make-local-variable 'time-stamp-end) "$")))
--8<---------------cut here---------------end--------------->8---

Of course, `time-stamp-format' may be changed according to your taste.

Shouldn't be such a thing be the default?


DATE was implemented exactly to specify a fixed date.  You can get
the modification date with

    {{{modification-time(%Y-%m-%d)}}}

and the current date with

    {{{date(%Y-%m-%d)}}}

These will be expanded upon export.  So you can, in fact, do

    #+DATE: {{{modification-time(%Y-%m-%d)}}}
