When is the Biblical Passover?

When is the proper time for the Biblical Passover? This has been a subject of controversy
dating to before the time of Christ. Can the proper date for the Passover be ascertained beyond reasonable doubt? Yes it can, as demonstrated in this carefully researched book. Also covered are related questions, such as on what day was Jesus Christ crucified? What day was he resurrected? Did the New Testament Church of Jesus Christ and the Apostles keep the Passover or Easter? Did the Church of God continue to keep the Passover, and were Christians persecuted for keeping Passover?
