That's actually how I'm doing it, but I'm not fully up on how macros
work short of just being text replacements. Currently, at the top of my
file, I have:
#+MACRO: gendate src_perl[:results output]{print ($1*5);}
# Where 'print ($1*5);' will later be replaced with a perl function that
takes the first day of class and an integer
# ex: /print find_date( '20160926', 6 );/ # 6 = Sixth lecture day,
output: "6, Oct 12, 2016" assuming MW class.
and in the org file, I can have headlines:
* Day {{{gendate(6)}}}
...
* Day {{{gendate(10)}}}
and so on. During export, the result desired is:
/Day 6, Oct 12, 2016/
{etc.}
FWIW, Eric had the solution:
#+MACRO: gendate src_perl[:results output _/*raw*/_]{print ($1*5);}
Thank everyone!

P.S. I should start a blog with all I learn on this. /Someone/ could
benefit from my struggles. :)
