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).
