Way way back...like in 1996 when I changed calendar to actually print the
date of variable event entries, like your Tue+2 entry (it used to print
"Tue+2", there were some issues with some month wraps, etc and some 
odd end cases that just displayed improperly.

A lot of times a normal calendar run would print just fine, but different
values of -A #### wouldn't match up.  Several years after making the changes,
I wished I had just gutted all of the date processing in calendar and 
started fresh instead of shoe-horning in the changes I made.

Around that time there was some debate about just importing OpenBSD's (or 
maybe it was NetBSD's) calendar so I left it alone and forgot about it.
That import never happened, and there are still some oddities floating
around, as you can see.
