[O] What is the best way to set #+DATE to today's date?

[Kaushal]

Hi all,

There are quite few documents in which I want to update the date stamp to the last update time.

I like that #+DATE keyword value is used aptly in latex/pdf and html exports.

But I couldn't find an elegant way for that date to be updated to today's (last updated) date.

I came up with the below. But please let me know if there's an inbuilt way to do the same.

PART 1: Config in init.el

    ;; Update TODAY macro with current date

    (defun modi/org-update-TODAY-macro (&rest ignore)

      "Update TODAY macro to hold string with current date."

      (interactive)

      (when (derived-mode-p 'org-mode)

        (save-excursion

          (goto-char (point-min))

          (while (re-search-forward

                  "^\\s-*#\\+MACRO:\\s-+TODAY"

                  nil 'noerror)

            (forward-line 0)

            (when (looking-at ".*TODAY\\(.*\\)")

              (replace-match

               (concat " "

                       (format-time-string "%b %d %Y, %a" (current-time)))

               :fixedcase :literal nil 1))))))

    (add-hook 'org-export-before-processing-hook #'modi/org-update-TODAY-macro)

PART 2: org document where I want the #+DATE to auto update

    #+MACRO: TODAY [current date is auto-inserted when exporting]

    #+DATE: {{{TODAY}}}
