When Michael visits Roth, Hyman is watching a college football game. Back then college football ended by Thanksgiving weekend, other than bowls on/around New Year's Day (at which time Michael/Roth were in Cuba).
I'd have to go back to listen but others have posted that the game broadcast was USC vs. Notre Dame. In 1958, they played on November 29th. So the Communion/shooting had to be before that.
