Yes, it looks like it works completly. (What I am missing is a knowledge
of Lisp. Thus that will come.)

One thing bugs me. I am used to end a formula ending with ';N'.
Sometimes if you do not do this, this geves an error. But in this case
this gives an error:
        Substitution history of formula
        Orig:   '(time-to-day-in-year (org-read-date t t (concat $2)))
        $xyz->  '(time-to-day-in-year (org-read-date t t (concat $2)))
        @r$c->  '(time-to-day-in-year (org-read-date t t (concat $2)))
        $1->    '(time-to-day-in-year (org-read-date t t (concat 2007)))
        Result: #ERROR
        Format: NONE
        Final:  #ERROR
When using nothing after the formula, I get:
        Substitution history of formula
        Orig:   '(time-to-day-in-year (org-read-date t t (concat $2)))
        $xyz->  '(time-to-day-in-year (org-read-date t t (concat $2)))
        @r$c->  '(time-to-day-in-year (org-read-date t t (concat $2)))
        $1->    '(time-to-day-in-year (org-read-date t t (concat #("2007-01-01" 0 1 (hilit-chg hilit-chg lazy-lock t) 1 2 (hilit-chg hilit-chg lazy-lock t) 2 3 (hilit-chg hilit-chg lazy-lock t) 3 4 (hilit-chg hilit-chg lazy-lock t) 4 5 (hilit-chg hilit-chg lazy-lock t) 5 6 (hilit-chg hilit-chg lazy-lock t) 6 8 (hilit-chg hilit-chg lazy-lock t) 8 9 (hilit-chg hilit-chg lazy-lock t) 9 10 (hilit-chg hilit-chg lazy-lock t)))))
        Result: 1
        Format: NONE
        Final:  1
And when I put ';S' after the formula, I get the same as with nothing
after the formula.
Why this error by ';N'?
Also what is the meaning of the strange expansion by concat? Maybe not
neccesary, but I like to understand what is happening.
