Hi, Orger friends :-)
I sometimes have to convert from a date to a week number, for when I am
shift-arrowing a clock table summarizing weeks. It was easy at the
beginning of the year, but I see it requires more thought as year
advance. I can write little programs to do so, but I wonder if someone
has an easy trick in Org mode (or in Emacs)?
If none, maybe that C-!, or something related to dates or calendar
display, could show the week number for each week? (random ideas! ...)

The agenda shows it in the daily/weekly view, so you can go to the date
of interest and do a day view: vd. Or you can crib the code that
calculates it and incorporate it into your own function
(org-days-to-iso-week does it but it requires a day number since BCE I
think, so you have to do some figuring).

Try this.
(org-odt-format-date "<2011-12-31 Sat>" "%U")
(org-odt-format-date "[2011-12-24 Sat]" "%U")
You can steal the implementation. The functions have nothing to do with
org-odt, btw.

Another way to get the week of the year is:
(require 'calendar)
(require 'cal-iso)
(car
(calendar-iso-from-absolute
(calendar-absolute-from-gregorian
(list month day year))))
