I would like to sum clock intervals from tasks by tag. I found this blog post (code below). When I use it, I get the same report, regardless of the tag I request:

Time: 4499:28 (4499 hours and 28 minutes)

Furthermore, I get this warning after evaluating the code:

‘org-re’ is an obsolete macro (as of Org 9.0); you can safely remove it.

The post is from 2008 and therefore I assume that the code is incompatible with my version.

How can I sum clocked intervals for a specific tag?

Appendix: here is the obsolete code:

(defun wicked/org-calculate-tag-time (matcher &optional ts te)
  "Return the total minutes clocked in headlines matching MATCHER.
MATCHER is a string or a Lisp form to be evaluated, testing if a
given set of tags qualifies a headline for inclusion. TS and TE
are time start (inclusive) and time end (exclusive). Call with a
prefix to be prompted for TS and TE.

For example, to see how much time you spent on tasks tagged as
URGENT, call M-x wicked/org-calculate-tag-time RET URGENT RET. To
see how much time you spent on tasks tagged as URGENT today, call
C-u M-x wicked/org-calculate-tag-time RET URGENT RET . RET +1 RET."
  (interactive (list
        (read-string "Tag query: ")
        (if current-prefix-arg (org-read-date))
        (if current-prefix-arg (org-read-date))))
  ;; Convert strings to proper arguments
  (if (stringp matcher) (setq matcher (cdr (org-make-tags-matcher matcher))))
  (if (stringp ts)
      (setq ts (time-to-seconds (apply 'encode-time (org-parse-time-string ts)))))
  (if (stringp te)
      (setq te (time-to-seconds (apply 'encode-time (org-parse-time-string te)))))
  (let* ((re (concat "[\n\r]" outline-regexp " *\\(\\<\\("
             (mapconcat 'regexp-quote org-todo-keywords-1 "\\|")
              "\\>\\)\\)? *\\(.*?\\)\\(:[[:alnum:][email protected]:]+:\\)?[ \t]*$")))
     (case-fold-search nil)
     tags tags-list tags-alist (llast 0) rtn level category i txt p
     marker entry priority (total 0))
      (org-clock-sum ts te)
      (goto-char (point-min))
      (while (re-search-forward re nil t)
    (catch :skip
      (setq tags (if (match-end 4) (match-string 4)))
      (goto-char (setq lspos (1+ (match-beginning 0))))
      (setq level (org-reduced-level (funcall outline-level))
        category (org-get-category))
      (setq i llast llast level)
      ;; remove tag lists from same and sublevels
      (while (>= i level)
        (when (setq entry (assoc i tags-alist))
          (setq tags-alist (delete entry tags-alist)))
        (setq i (1- i)))
      ;; add the nex tags
      (when tags
        (setq tags (mapcar 'downcase (org-split-string tags ":"))
          (cons (cons level tags) tags-alist)))
      ;; compile tags for current headline
      (setq tags-list
        (if org-use-tag-inheritance
            (apply 'append (mapcar 'cdr tags-alist))
      (when (and (eval matcher)
             (or (not org-agenda-skip-archived-trees)
             (not (member org-archive-tag tags-list))))
        ;; Get the time for the headline at point
        (goto-char (line-beginning-position))
        (setq total (+ total (or (get-text-property (1+ (point)) :org-clock-minutes) 0)))
        ;; if we are to skip sublevels, jump to end of subtree
        (org-end-of-subtree t)))))
    (if (interactive-p)
    (let* ((h (/ total 60))
           (m (- total (* 60 h))))
      (message "Time: %d:%02d (%d hours and %d minutes)" h m h m)))

    There are a couple of questions already answered about clocking tables and tags, like this or more probably this. I do understand that you're after a different use case, but further clarification will help.

  • I agree with @Muihlinn: instead of showing what code does not work, you should show an example org file and what you expect to get.

  • The solution with the clock report in the second link (stackoverflow.com/questions/38545767/…) worked for me (#+BEGIN: clocktable :maxlevel 2 :scope file :tags "nicetag"). I can't mark it as a duplicate: would you like to write an answer? Thanks for the comment @NickD: next time I'll ask what I want to do first, and add an example of a way that failed after.

    Yes, the "duplicate" is on SO. You can always write your own answer and accept it though (and a "link-only" answer might be acceptable in this case).

1 Answer 1


Following the link @Muihlinn's comment, one solution consists of a clock report:

#+BEGIN: clocktable :maxlevel 2 :scope file :tags "nicetag"

I can't mark this question as a duplicate since the other solution is on a different forum.
