How can I have more control over repeating tasks in Org?

Question

I began exploring org-mode lately and I love it. But, I'd like to know how I can have more control over repeating tasks, like if I've set a task to repeat everyday, how can I make it exclude weekends?

Also, is there a option like a holiday mode or something similar which when turned on asks for the duration i'll be away and all my repeating tasks(if I have any that are scheduled during the time I take off) are rescheduled automatically to the next scheduled day after the holiday ends.

My solution:

1. Tag items 'winter', 'weekends', 'schoolnights', etc.

2. Make sure each of these tags has an associated speed-key in org-tag-alist.

3. Write a predicate for each tag that tells you if it is not current: not-winter-p (returning non-nil between April and November in the northern hemisphere), weekdayp, not-schoolnight-p, etc.

4. Put it all together in your own agenda command:

(Ah-ha! Discovered I have to put non-numbered-list text here to make following code appear properly formatted)

(defun ph/agenda ()
  "Display my agenda."
  (interactive)
  (org-agenda-list)
  (cl-loop
    for (predicate . speed-key)
    in
    '((weekendp . ?\[)
      (winterp . ?\])
      (not-schoolday-p . ?\{)
      (not-schoolnight-p . ?\}))
    when (funcall predicate)
    do (org-agenda-filter-by-tag nil speed-key 'exclude)))

Answer 2

You could use diary dates. I have an event that happens every 1st, 3rd, and 5th Friday of the month.

* Music Jam
   <%%(diary-float t 5 1)>
   <%%(diary-float t 5 3)> 
   <%%(diary-float t 5 5)>

There are other diary functions too. diary-float, diary-remind, diary-cyclic, etc. You can read more about this via

      M-x info RET org RET m Agenda  

Search for diary, and you'll find it. (C-s diary)
