Hide items with a certain tag in agenda based on time of day

Question

Is it possible to hide items with a certain tag after at specific time of the day? For example, I'd like that after 5pm and on weekends, :WORK: items don't appear in the agenda.

EDIT: I am dealing with scheduled items and relying on org-agenda-list function.

Answer 1

You can customize skipping specific entries in org-agenda by using a skip function. This is a function (or lisp form) that will be evaluated at each headline and should return nil (to not skip the headline) or the point of the next headline to consider (which is typically the next headline, but could be, for example the next sibling to speed the search up).

In this case, we just need a function to skip the headline if it has a certain tag (get those with org-get-tags-at) and the (current-time) is after a certain hour:

(defun skip-tag-after (tag hour)
  (let* ((next-headline (save-excursion
                          (or (outline-next-heading) (point-max))))
        (current-headline (or (and (org-at-heading-p)
                                   (point))
                              (save-excursion (org-back-to-heading))))
        ;; (now (decode-time (current-time)))
        (target (decode-time (current-time)))
        (day (nth 6 target))
        )
    (setcar (last target 7) hour)
    (setcar (last target 8) 0)
    (if (and (member tag (org-get-tags-at current-headline))
             (or (eq day 0)
                 (eq day 6)
                 (time-less-p (apply #'encode-time target) (current-time))))
            next-headline
            nil)))

This doesn't consider the weekday, but that logic

You can either (setq (setq org-agenda-skip-function-global '(skip-tag-after "WORK" 17)) to skip such headlines globally in every agenda, or set it set org-agenda-skip-function locally inside a org-agenda-custom-command to affect just that agenda.

Answer 2

A very simple workaround would would be to make a special agenda view (or views) that you only use on evenings and weekends.

To give a very simple example, you could customize org-agenda-custom-commands by adding something like ("x" "No Work" tags-todo "-work" nil). Then on evenings and weekends you can pull up your overall agenda view with C-c a x.
