Repeat every X business days and every Xth day-of-the-week

Repeat every X business days and every Xth day-of-the-week

[Jay McCarthy]

Dear org-mode developers,

I wish that I could write +1bd on a repeating tasks so that it skips
from Friday to Monday.

I looked into implementing this myself, but there are a lot of places
(29) where the regexp [dwmy] is used and it scares me off because I
think I'll break something. It almost seems like you should be able to
add a new 'what' to 'org-timestamp-change' and it will Just Work. But
the algorithm in there would need to change a bit, because it would
try to change by a number of days, but then adjust based on the advic
day of the week.

For now, I just manually complete the task on Saturdays and Sundays...
but it seems wrong to get credit in the TODO -> DONE log when I really
didn't do it :)

I also wish that I could specify in some way that an event happens
every third Thursday of the month or on the first and third Wednesdays
(when my recycling cans are picked up). I don't know of a good way to
fit that into the current annotation scheme of + and ++.

If you have any advice about how I could do it myself safely, I'd be
happy to try and contribute.

Jay

Diary s-exprs can do things like this:

--8<---------------cut here---------------start------------->8---

* TODO every third Thursday of the month
  <%%(org-float t 4 3)>

* TODO every first and third Wednesday of the month
  <%%(or (org-float t 3 1) (org-float t 3 3))>
--8<---------------cut here---------------end--------------->8---

Except these TODO's don't behave like repeating tasks.  If you mark it
DONE it stays DONE as opposed to cycling back to TODO for the next
occurrence.

You can also just adjust the date with S-right until the next
occurrence - this doesn't mark it DONE.  Then you don't get 'credit' for
doing it on weekends.

HTH,
