I'm trying to come up with a sexp diary entry that shows my payday,
which is the last weekday of the month, in my Org agenda. I've tried
to adapt the example given in the Emacs manual and this is what I came
up with:
%%(let ((month (car date))
(day (cadr date))
(dayname (calendar-day-of-week date)))
(or
;; months with 31 days
(and (memq month '(1 3 5 7 8 10 12))
(or (and (= day 31)
(memq dayname '(1 2 3 4 5)))
(and (memq day '(29 30))
(= dayname 5))))
;; months with 30 days
(and (memq month '(4 6 9 11))
(or (and (= day 30)
(memq dayname '(1 2 3 4 5)))
(and (memq day '(28 29))
(= dayname 5))))
;; February (the weird one)
(and (= month 2)
(or (and (memq day '(28 29))
(memq dayname '(1 2 3 4 5)))
(and (memq day '(26 27 28))
(= dayname 5)))))) Chris' Paycheck Deposited
It appears to work so far. However, I'm certain there's got to be a
more concise way of coding this, but I can't seem to find any
pre-existing calendar functions that might help. Am I missing
something?
To make this even better, is there some way to consult another file of
diary entries containing all the holidays at my workplace, so the
diary entry would show up on the last weekday of the month that is not
a company holiday?
Thanks!
Chris

This is based on the same idea and example from the manual, but it
precalculates what it needs in order to simplify the decision at
the end:
(let* ((dayname (calendar-day-of-week date))
(day (calendar-extract-day date))
(month (calendar-extract-month date))
(year (calendar-extract-year date))
(lastday (calendar-last-day-of-month month year))
(last-two-days-before-last-day (list (- lastday 2) (- lastday 1))))
(or (and (= day lastday) (memq dayname '(1 2 3 4 5)))
(and (memq day last-two-days-before-last-day) (= dayname 5)))
)
Very lightly tested, so use with caution.

I'm sure there is - simplest is probably to set a variable in your
.emacs with all the holidays - schedule that with org for Dec. 31 :-) -
but you are on your own for that. I just don't think it's worth it: at
least for me, there are only three holidays during a year that might
interfere with that pay schedule.
HTH,

Where do the functions 'calendar-extract-day',
'calendar-extract-month', 'calendar-extract-year', and
'calendar-last-day-of-the-month' come from? I was looking for
something like those when I wrote my initial implementation, but I
don't seem to have them (hence the ugliness of the code!) I'm running
GNU Emacs 23.2 for Mac OS X. Searching for these functions using `C-h
f` turns up nothing for me.
Thanks for the help,
Chris

Never mind... I think I had something messed up in my initialization
file; they're showing up now.
