got to Memorial Day and Easter. I decided to scrap Easter due to it being
based on the lunar cycle, had no idea how to calculate that one.

You and me both but here is a post by the late George Simms from 4 Dec 2000:

Hi Anthony,

This formula was by Thomas Jansen from Germany. It came second in a contest
to find the shortest formula to calculate the date for Easter Sunday for
any year between 1900 to 2078. You will need to ask him the "how" and
"why" it works.

The winning formula was by Norbert Hetterich from Germany with :

=FLOOR(DAY(MINUTE(A1/38)/2+56)&"/5/"&A1,7)-34

Again I don't know how and why it works, but it does.

The contest was run by Hans Herber http://www.herber.de

BTW. I came 20th (Last) <bg

All the Best
