Thanks for the work.
But why do you call this timeline definitive? Definitive according to who or what?
There are a lot of contradictions:
- within the novel (e.g. return of Michael)
- between novel and film(s) (e.g. massacre)
- between GF and GF2 (e.g. birth of Vito)
Some events aren't mentioned at all. How can you tell the year of Fredo's wedding?
He got this timeline over here where it includes notes about those contradictions.
