Is it possible to convert plain text dates to Org dates automatically? I have entries in the format:

16 February 2015

which I would like to convert to Org dates: <2015-02-16 Mon>


Internally, org-mode uses the function org-read-date to do this:


For example,

(org-read-date nil nil "16 February 2015")

returns "2015-02-16". This doesn't put in the "<>" or "[]" for active/inactive time-stamps, but you can easily add them with a format:

(format "<%s>"   (org-read-date nil nil "16 February 2015"))
  • 1
    And pressing C-c c on the result will add in the day of the week. – SabreWolfy May 27 '15 at 11:03

I came up with something like this:

(defun my-format-time (time-string)
  (let* ((time (parse-time-string time-string))
         (day (nth 3 time))
         (month (nth 4 time))
         (year (nth 5 time)))
    (format-time-string "<%Y-%m-%d>" 
      ;; I would love to do an 'apply here, but the given list to be encoded contains nil which does n
      (encode-time 0 0 0 day month year))))

With that you can create an interactive function that scans for your specific date format and replaces the found date strings with the desired format.

  • Can you explain how to use this? I added (interactive) on the second line, selected date text and ran the function, but got an error about parameters. – SabreWolfy May 26 '15 at 11:54
  • @SabreWolfy You'll need to tell Emacs how to retrieve the time string, like with (interactive "r") – wasamasa May 26 '15 at 11:59
