Huh, that sounds interesting. What I did was define this function:
;; this is the one I'm currently using
(defun get-ts+7 ()
"returns a string of the form <%Y-%m-d %a> where the date elements are 7
days later
than the previous timestamp in the buffer. No error checking or anything
yet."
(interactive)
(let ((base-date (save-excursion
(re-search-backward
(org-re-timestamp 'all))
(match-string 0)))
(result nil))
(format-time-string "<%Y-%m-%d %a>"
(time-add
(date-to-time base-date) (days-to-time (1+ 7))))
))
And then I use this macro:
#+MACRO: ts (eval (get-ts+7))
And then my headings look like this:
* Week {{{n}}} (<2017-09-11 Mon>):Intro. On Discussion.
* Week {{{n}}} ({{{ts}}}): What is a River?
* Week {{{n}}} ({{{ts}}}): Rivers in the Broad Sweep of Time
It's not easy to look at in its org-native form, but it's pretty good on
export.
