In the movie, the scene in which Michael meets Kay again takes place during Autumn. Based on the movie timeline, it would have been before 1951 when Anthony was born. The Annotated Godfather lists it as Autumn 1950, but in regards to Turnbull's timeline of the novel, it would rather be late 1948.

"It was between the brothers Kay -- I had nothing to do with it."
