@Nick That works! Thank you!
I used the below instead (learned that I needed to escape that comma).
#+DATE: {{{time(%b %d %Y\, %a)}}}
I had read about {{{date}}} but assumed that {{{time}}} does the same thing
as {{{date}}} because they are put together with the same description. The
documentation actually doesn't tell what {{{time}}} does:

@John: Looks like I will not need any elisp hacks :)
