In the Christian gospels, the ministry of Jesus begins with his baptism in the countryside of Roman Judea and Transjordan, near the river Jordan, and ends in Jerusalem, following the Last Supper with his disciples. The Gospel of Luke (3:23) states that Jesus was "about 30 years of age" at the start of his ministry. A chronology of Jesus typically has the date of the start of his ministry estimated at around 27-29 AD/CE and the end in the range 30-36 AD/CE.

Jesus' Early Galilean ministry begins when after his Baptism, he goes back to Galilee from his time in the Judean desert. In this early period he preaches around Galilee and recruits his first disciples who begin to travel with him and eventually form the core of the early Church as it is believed that the Apostles dispersed from Jerusalem to found the Apostolic Sees. The Major Galilean ministry which begins in Matthew 8 includes the commissioning of the Twelve Apostles, and covers most of the ministry of Jesus in Galilee. The Final Galilean ministry begins after the death of John the Baptist as Jesus prepares to go to Jerusalem.
