Hi, I'm having the exact same issue as this question on stackoverflow http://stackoverflow.com/questions/18123972/emacs-org-mode-clear-non-repeated-scheduled-time-when-deadline-is-repeated and I've copied it below. The solution provided to the question modifies the source, which I'd like to avoid if possible. Is there a better way of doing this like by setting a variable or a hook? Or does anyone have better ideas about this type of workflow? Question: > I use org-mode to manage some deadlines for repeated tasks. For example, I > may have something like the following: > * TODO My Weekly Task > DEADLINE <2013-08-10 Sat +1w> > If I mark the task as DONE, then the deadline automatically increments to > the next week as expected.
