How much time passed between the crucifixion and Peter's statement in Acts 3?
Approximately eight or nine weeks passed between the crucifixion and Peter’s statement in Acts 3. This event occurred only about eight or nine weeks after the crucifixion, and the preceding three years and a few months are what Peter references.
The context explains that Peter’s statement in Acts 3 is given only about eight or nine weeks after the crucifixion. Counting backward three years from that point, the entire period Peter refers to spans only about three years and a few months. Peter argues that all these events were in fulfillment of what God had said. The passage also stresses that this message is Jewish, since Gentiles are excluded from the lineage of Israel, and the Messiah came through Israel as the vehicle.
