Jordan. The gospels present John the Baptist's ministry as the precursor to that of Jesus and the baptism of Jesus as marking the beginning of Jesus' ministry, after which Jesus travels, preaches and performs miracles.The Cradle, the Cross, and the Crown: An Introduction to the New Testament by Andreas J. Köstenberger, L. Scott Kellum 2009 p. 141–143. Jesus's baptism is generally considered the beginning and the Last Supper with his disciples in Jerusalem as the end of his ministry. However, some authors also consider the period between the Resurrection and the Ascension part of the ministry of Jesus. Luke states that Jesus was "about 30 years of age" at the start of his ministry. There have been different approaches to estimating the date of the start of the ministry of Jesus.Eerdmans Dictionary of the Bible 2000 Amsterdam University Press p. 249.Luke 1–5: New Testament Commentary by John MacArthur, Jr. 2009 p. 201. One approach, based on combining information from the Gospel of Luke with historical data about Emperor Tiberius yields a date around 28–29 AD/CE, while a second independent approach based on statements in the Gospel of John along with historical information from Josephus about the Temple in Jerusalem leads to a date around AD 27–29.The Riddles of the Fourth Gospel: An Introduction to John by Paul N. Anderson 2011 p. 200. In the New Testament, the date of the Last Supper is very close before the date of the crucifixion of Jesus (hence its name). Scholarly estimates for the date of the crucifixion generally fall in the range AD 30–36.Paul's early period: chronology, mission strategy, theology by Rainer Riesner 1997 pp. 19–27 (p. 27 has a table of various scholarly estimates) The three Synoptic Gospels refer to just one passover, specifically the Passover at the end of Jesus's ministry when he is crucified (with the exception of Luke's Gospel, which narrates a visit of the Holy Family for Passover when Jesus is twelve years old). There are three references to Passovers in John's Gospel: 2:13, 6:4, and 12:1. Some contend that the Gospel of John refers to only two actual Passovers, one at the beginning of Jesus's ministry and the second at the end of Jesus's ministry, and that the third reference to Passover is only a forecasting of the second Passover in the Gospel of John. But much scholarship recognizes that a lot of time passes between 6:4,
