How any people were baptized on Pentecost?

On Pentecost, as described in the Book of Acts in the New Testament, about 3,000 people were baptized after the Apostle Peter delivered a sermon to the gathered crowd. This event marked the beginning of the Christian Church and is celebrated as a significant moment in Christian history. The rapid growth of the early church was fueled by this mass baptism and the subsequent teachings of the apostles.
