I know the year of JFK’s assassination was 1963 but not the month or day. I may remember it going forward because of this thread, though, because that’s the way my brain works.
I was born in 1970.
I’ve never heard the date"Nov 11" as a refrain the way “September 11” or “9-11” is, or in FDR’s speech about “December 7th, a date that will live in infamy*”, or the rhyme about Guy Fawkes Day (“remember, remember, the fifth of November / The gunpowder, treason, and plot…”) that featured in “V For Vendetta” (not being British, that was my initial exposure to it).
Or the Temptations singing about how “It was the third of September, a day I’ll always remember (yes, I will) / 'Cause that was the day that my Daddy died”
*Note: Dec 7 is also the birthday of the first girl I ever had a serious crush on, and I’ve remembered it for that reason since I was 9 years old, and it’s the mnemonic I have for remembering the date in FDR’S speech
