The following events occurred on November 12.
- Marty: "You're not gonna believe this. We gotta go back to 1955!"
- Doc: "I don't believe it!"
- Marty: "That's right, Doc. November 12th, 1955."
- Doc: "Unbelievable that Old Biff could've chosen that particular date. It could mean that that point in time inherently contains some sort of cosmic significance, almost as if it were the temporal junction point of the entire space-time continuum. On the other hand, it could just be an amazing coincidence."

November 12, 1955 was one of the most event-filled dates in Hill Valley history.
