I liked the idea of org-diary-class!
About avoiding holidays and certain weeks:
I used remind and wyrd for a while and 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) to 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
