Hello everybody it is quite easy question.

I'm using org-mobile so it synchronize my android agenda with org mode.

When I use org-deadline (C-c C-d) and I choose today, the format will look like this: DEADLINE: <2015-08-03 Pzt>,

I just want it to make all deadlines always be at 10 am instead, like this: DEADLINE: <2015-08-03 Pzt 10:00>. I would also like the same behaviour with org-schedule (C-c C-s).

How can achieve this?

  • You can type in a date with time at the prompt like this: January 5, 2015 10:00. You can also insert the current date programmatically with a specified time like this: (org-deadline nil "10:00") or (org-scheduled nil "10:00"). Look at the doc-string for org-read-date to familiarize yourself with the acceptable formats -- M-x describe-function RET org-read-date RET.

org-deadline works by calling org-add-planning-info, with org-deadline's input (nil if you call it with C-c C-d) and gets a default time from org-parse-time-string, which is hard-coded to today at 00:00. So there is no variable we can easily change to set the default time.

This default time is then passed to org-read-date which gets the user input and does take an argument letting us set our own default time. Thus, we can advise org-deadline to call a different version of org-read-date whose default time is some value we set:

(require 'cl-lib)

(defvar org-deadline-default-time "10:00"
  "The default time for deadlines.")

(defun advise-deadline-default-time (deadline-func arg &optional time)
  (let ((old-time (symbol-function #'org-read-date)))
    (cl-letf (((symbol-function #'org-read-date)
               #'(lambda (&optional a b c d default-time f g)
                   (let ((default-time (or default-time
                     (apply old-time a b c d f default-time g)
      (apply deadline-func arg time)

(advice-add #'org-deadline :around #'advise-deadline-default-time)
  • I don't know. It does not work directly when I copied it. Nothing changed When I used C-c C-d Aug 4, 2015 at 9:38
  • I've edited in some bug fixes. It's working for me except with when there is already a deadline on the entry.
