I know it is complex.

I thought about the first steps

I was thinkin= g about a variable (list?) with predefined holidays

or better omit-holidays

such a= s org-omit-holidays

we could add the omit dates in any pl= ace=A0

=A0=A0(add-to-list 'org-omit-holidays "1 Jan")
=A0=A0(add-to-list 'org-omit-holidays "1 May")
etc.


Then we could change (a= dapt) the=A0

function calendar-check-holydays from holidays.el

I did a search-replace to something like= this:

(defun org-check-calendar-omit-holiday= s (date)
=A0=A0"Check the list of org-omit-holidays for any that occur on = DATE.
The value returned is a list of strings of relevant org-omi= t-holiday descriptions.

Hi Daniel,

I liked the idea of org-diary-class!

I have added the function now to org-agenda.el



About avoiding holidays and certain weeks:

I used remind and wyrd for a while =A0and they are a quite good software for dealing with such appts.

There we have the OMIT function where we determine holidays and other
non-working days including Sat and Sundays


Normally we have an OMIT list at the beginning of file

Some functions simply omit those dates

Other expressions use another keyword AFTER (or BEFORE) =A0to change
OMIT behaviour

like
23 Mar AFTER OMIT "Bank payment"

eg If 23 Mar is in Saturday it will appear in Monday

This preamble is just to say 2 things:

1) remind/wyrd could be used as a benchmark for some of the calendar
isuues we have

2) I do not know if the week number in a year is a practical way of
setting exceptions to org-diary-class

Daniel

PS Wyrd page is

Interesting. =A0But too complex for now - and I actually do prefer local co= ntrol.

Hi Daniel,

I think it is a good idea to add such a function to org-mode. =A0But I
am not sure if skipping holidays is the best, because Universities
also have lecture-free weeks etc.

So I am more thinking about a function like this (untested)

(defun org-diary-class (m1 d1 y1 m2 d2 y2 dayname &rest skip-weeks)
=A0"Entry applies if date is between dates on DAYNAME, but skips SKIP-= WEEKS.
Order of the parameters is M1, D1, Y1, M2, D2, Y2 if
`european-calendar-style' is nil, and D1, M1, Y1, D2, M2, Y2 if
`european-calendar-style' is t. =A0The weeks are ISO week numbers where=
the item should not apply."
=A0(let* ((date1 (calendar-absolute-from-gregorian
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(if european-calendar-style
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(list d1 m1 y1)
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(list m1 d1 y1))))
=A0 =A0 =A0 =A0(date2 (calendar-absolute-from-gregorian
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(if european-calendar-style
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(list d2 m2 y2)
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(list m2 d2 y2))))
=A0 =A0 =A0 =A0(d (calendar-absolute-from-gregorian date)))
=A0 (and
=A0 =A0(<=3D date1 d)
=A0 =A0(<=3D d date2)
=A0 =A0(=3D (calendar-day-of-week date) dayname)
=A0 =A0(or (not skip-weeks)
=A0 =A0 =A0 =A0(progn
=A0 =A0 =A0 =A0 =A0(require 'cal-iso)
=A0 =A0 =A0 =A0 =A0(not (member (car (calendar-iso-from-absolute d)) skip-= weeks))))
=A0 =A0entry)))


What do you think?

However a sentence like this:

Maybe as a suggestion we could encapsulate such a huge expression in a
simpler org-mode function ?

Daniel


PS In

http://www.emacswiki.org/cgi-bin/wiki/DiaryMode#toc12

I found another suggestion which I do not know how to include in org-mode

------------------------------------
Schedule

If you want to write a schedule for school or university, you need to
define a block (it=92s derived from diary-block) between two dates and a weekday. The following function also recognizes holidays and won=92t
send you to school on those days=85 :)

=A0(defun diary-schedule (m1 d1 y1 m2 d2 y2 dayname)
=A0 =A0"Entry applies if date is between dates on DAYNAME.
=A0Order of the parameters is M1, D1, Y1, M2, D2, Y2 if
=A0`european-calendar-style' is nil, and D1, M1, Y1, D2, M2, Y2 if
=A0`european-calendar-style' is t. Entry does not apply on a history.&= quot;
=A0 =A0(let ((date1 (calendar-absolute-from-gregorian
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(if european-calendar-style
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(list d1 m1 y1)
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(list m1 d1 y1))))
=A0 =A0 =A0 =A0 =A0(date2 (calendar-absolute-from-gregorian
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(if european-calendar-style
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(list d2 m2 y2)
=A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0(list m2 d2 y2))))
=A0 =A0 =A0 =A0 =A0(d (calendar-absolute-from-gregorian date)))
=A0 =A0 =A0(if (and
=A0 =A0 =A0 =A0 =A0 (<=3D date1 d)
=A0 =A0 =A0 =A0 =A0 (<=3D d date2)
=A0 =A0 =A0 =A0 =A0 (=3D (calendar-day-of-week date) dayname)
=A0 =A0 =A0 =A0 =A0 (not (check-calendar-holidays date))
=A0 =A0 =A0 =A0 =A0 )
=A0 =A0 =A0 =A0 =A0 entry)))

Then: "&%%(diary-schedule 22 4 2003 1 8 2003 2) 18:00 History"= ;

We need to create a schedule for a period.

The package "remind" (and its simple interface "wyrd") = do this job
wonderfully but I do not know how to deal with this problem in Org

The following FAQ should help:
