That works for the next two years, so thank you!

I also want to send myself a reminder the previous Friday when there's 
an event on one of those Thursdays.  That was trickier, but this is what 
I came up with:

OMIT 26 November 2020 # Thanksgiving
REM Thu --6 SKIP SATISFY [!isomitted($T+6) && (day($T+6) < 3 || day($T+6) > 9)] \
    RUN send_email -s "send meeting email for [$T+6]"

I could have distributed the +6 for the > 9 test ("day($T) > 3"), but 
couldn't figure out how to do that for the other test so left it.

This works, but I'm not thrilled by having to sprinkle $T+6 all around.  
Is there a better way of accomplishing the same thing?
