Ah. Where can I find documentation on “the special sexp diary entries
implemented in the Emacs calendar/diary package”?

Hmm. That makes the entry unreadable as a date+time. One of the main

perfectly readable even to people who know nothing about Org, Emacs, or
Lisp. Is there a way to get a readable format that still behaves as I
described?
