Short answer: I don't know.
Longer answer: Vito returned to the Mall some time in 1946, probably spring or summer. Michael was still in Sicily. The next we see of Michael in America is when he woos Kay in New Hampshire, and he tells her, "I've been back a year." The next we see of Michael after that is the trip to Vegas. How much time elapsed overall is uncertain--more than a year, probably less than five years.


Ntra la porta tua lu sangu � sparsu,
E nun me mporta si ce muoru accisu...
E s'iddu muoru e vaju mparadisu
Si nun ce truovo a ttia, mancu ce trasu.
