Hi, In the following example, when I try to sort on the top heading (Planner 2014-15) for time, the heading Holiday does not sort correctly (unless I promote the heading to **. Is there a way that a sort can work with all the children of a given heading? I have also tried selecting all the headings and sorting but with no success. * Planner 2014-15 #+CATEGORY:PLN ** INSET DAY <2014-09-04 Thu> ** INSET DAY <2014-09-05 Fri> *** Holiday <2014-10-27 Mon>--<2014-10-31 Fri> ** B Meeting <2014-09-22 Mon> ** C Committee <2014-10-02 Thu> ** S Committee <2014-10-23 Thu> ** FS <2014-11-06 Thu> ** M Meeting <2014-11-27 Thu> Many thanks, Simon.
