I'm using the spreadsheet capabilities of org for the first time (very
cool!) to plan an upcoming trip. I'd like to create a column formula to
automatically calculate the dates/day of week but I'm a bit stumped. I
don't see a way for the formula to know which row it is currently
processing. I'm also coming up short trying to find any elisp to go from
day of year -> formatted date string. Any suggestions?

Can you give an example table of what you want to do?
I do not understand fully.
| A | B |
|------------------+-----|
| [2010-03-16 Tue] | Tue |
| [2010-03-17 Wed] | Tue |
| | |
Do you want to automatically extract the weekday from an org-mode
time-stamp in another column?

Hi Josh,
Could you provide a small example table that shows the challenge you are
describing?

Sure thing. Basically I'd like the "date" column to be automatically
calculated so that I can move things around, add extra days here and there,
and not have to edit that column by hand.
| date | location | activities | notes |
|-----------+----------+---------------+----------------------------|
| 03-16 Tue | moon | collect rocks | |
| 03-17 Wed | mars | terraform | this might take a few days |
| 03-18 Thu | earth | breath air | |
If I wanted to add an extra day on mars I could just enter a new row,
recalculate the forumula, and the dates would be automagically updated.
It's not such a big deal in a small example like this but I'm planning out a
3 week vacation with a fair number of destinations. I'd like the day of
week to display because some sites are closed on certain days.
It goes without saying that I've spent more time trying to figure this out
than it would actually save so it's more about education at this point :)

Hey Nick, the first one came through just fine. This is pretty cool but
still not quite what I'm looking for. It totally helped me get what I
wanted though! I wanted to have a separate row for each day so I could fill
in activities. Modifying your example I get:
| date | place | activity | notes
|
|------------------+---------+---------------------------+------------------|
| <2010-03-19 Fri> | | | dummy
|
| <2010-03-20 Sat> | | |
|
| <2010-03-21 Sun> | moon | collect rocks |
|
| <2010-03-22 Mon> | jupiter | thrash around the red dot |
|
| <2010-03-23 Tue> | mars | see the little green men |
|
| <2010-03-24 Wed> | earth | | home, sweet home
|
#+TBLFM: @2$1 = <03-19-2010>::$1 = @-1$1 + 1
Exactly what I wanted! I can insert days, move them around, and just hit
C-u C-c C-c to have it update. I'd like to understand how it works though,
if you don't mind. What does the ::$1 synax mean? And how did it know that
we were dealing with a date?

As I understand it
This is a formula line with 2 formulas in it. The formulas are
separated by the ::
@2$1 = <03-19-2010> sets the cell at row 2, column 1 to Mar 19, 2010
Then the next formula just calculates all of the values for column 1
leaving the static entry previously defined alone.
$1 = @-1$1 + 1 column 1 entries are the previous row for column 1 plus 1
so it just adds 1 to the initial value of the date for each following
row in your table.
HTH,
Bernt

And the magic is that calc understands date and knows how to do
arithmetic with them.

Well, you can use the full power of both Emacs Lisp and Emacs Calc in
the org spreadsheet cells so the following works (although maybe it's
not quite as pretty as you would like...):
--8<---------------cut here---------------start------------->8---
| date number | date | activity |
|-------------+--------------------+----------|
| 733850 | <Thu Mar 18, 2010> | swim |
| 733851 | <Fri Mar 19, 2010> | run |
| 733852 | <Sat Mar 20, 2010> | eat |
#+TBLFM: $1=1+@-1::$2='(calc-eval (concat "date(" $1 ")"))::@2$1='(calc-eval "date(now())");%d
--8<---------------cut here---------------end--------------->8---
The first column are date numbers which are then shown in text in the
second column. the first date is currently set to "today" but this
could be any specific date by simply replacing "now()" by say
"date(3,18)" for 18 March.
I'm sure it can be done more expertly by others, of course, as I am
definitely not up to speed with calc.
Hope this helps.
