Preferably, they have some other connection to each other (nationality, discipline, occupation, etc.). This is inspired by the recent deaths of Antonioni and Bergman. I’m not talking about mid-level celebrities, but highly visible, household names. Ones I have so far:
John Adams & Thomas Jefferson
C.S. Lewis & Aldous Huxley (plus JFK)
Yul Brynner & Orson Welles
Joseph Stalin & Sergei Prokofiev
Sammy Davis Jr. & Jim Henson
I’m sure there are a lot more, but I was hoping to limit things to really big names.
Spain and England adopted the Gregorian calendar in different years. When they made the change they had to adjust by 10 days (11 by the time England did it) to get back on track with solar time. In the 17th century, there was effectively a 240-hour time-zone difference between Spain (or France, for that matter) and England.

As you noted, John F. Kennedy and C.S. Lewis both died on Nov. 22, 1963. Lewis’s death didn’t receive nearly the attention it would have otherwise. Hadn’t known about Aldous Huxley.
Adolf Hitler and Eva Braun, and Joseph Goebbels, his wife and family, all died on the same day in the Fuhrerbunker, April 30, 1945.
