12/21 - death of Gen. Patton. Most of the awake know that he was killed.
(And fwiw, there's a theory about Trump being the reincarnation of Patton. I don't worry about that stuff, but ... it's interesting that on D-Day he led Operation Fortitude, often described as the largest and most successful wartime deception operation in modern history.)
All Presidents are Inaugurated on 1/20. (Jan 20 falling on Sunday only pushes the public ceremony to the 21st, President still sworn in at noon on 20th).
Not all have been inaugurated on 1/20, only started happening recently within the United States.
