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. > 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? > 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.
