How old was Jesus when he began to ministry?

Answer 1

He never had a 'ministry' in the sense that we know today. In the eyes of his Jewish contemporaries he was a 'wandering rabbi' - a Jewish tradition that remained very common all over middle and eastern Europe until WW 1, including the disciples and the miracle stories attributed to them. Since he died in his early thirties, it is probable that he had been 'active' so to speak for the last 5 (probably) to 10 years before that. That would have made him some 25 years old when he started preaching.

Answer2: Luke 3:23 "When Jesus began his work, he was about 30 years old..."

Answer 2

• Luke: "In the fifteenth year of the reign of Tiberius Caesar" (iii, 1). "Jesus himself began to be about thirty years of age" (23).

  In the fifteenth year of Tiberius, who began his reign in August, 14 A.D., Jesus, according to Matthew, was at least thirty-three years of age; according to Luke, about twenty-two.

  Regarding this subject, Dr. Geikie writes as follows: "The age of Jesus at his entrance on his public work has been variously estimated. Ewald supposes that he was about thirty-four, fixing his birth three years before the death of Herod. Wieseler, on the contrary, believes him to have been in his thirty-first year, setting his birth a few months before Herod's death. Bunsen, Anger, Winer, Schurer, and Renan agree with this. Lichtenstein makes him thirty-two. Hausrath and Keim, on the other hand, think that he began his ministry in the year AD. 34, but they do not give any supposed date for his birth, though if that of Ewald be taken as a medium he must have been forty years old, while, if Wieseler's date be preferred, he would only have been thirty-seven ... Amidst such difference, exactness is impossible" (Life of Christ, Vol. I, pp. 455, 456).

• From the death of Herod, a comet, and a census we can narrow down Jesus' birth to 5-6 B.C. According to Luke, Jesus was around 30 years old when he started his ministry. His ministry started around A.D. 26-27 (cross reference rulers mentioned with other records outside of The Bible). If you count the number of Passovers (a yearly feast) mentioned, his ministry lasted for at least 2 years, take into account another unknown feast, likely over 3 years. Because of the day of the week he was crucified on (and the day he rose from the dead) he either died in A.D. 30 or A.D. 33.
  

• According to most Bible scholars Jesus was born in 4 BC (either the spring or the fall) by our modern calendar and began His ministry around 27 AD (age 30). The time of Jesus' birth and the duration of His ministry was prophesied in Daniel 7. Although He performed His first miracle at the wedding in Cana, this didn't quite mark His public ministry. In fact for the first year of Jesus' ministry, much of it was done in private.
  

• Luke3:23 tells us: "And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph..."

Luke was intent on getting details, telling us in verse 1: "Now in the fifteenth year of the reign of Tiberius Caesar, Pontius Pilate being governor of Judaea, and Herod being tetrarch of Galilee, and his brother Philip tetrarch of Ituraea and of the region of Trachonitis, and Lysanias the tetrarch of Abilene, Annas and Caiaphas being the high priests, the word of God came unto John the son of Zacharias in the wilderness." It was at this place, where John the Baptist baptized Jesus, and "the Holy Ghost descended in a bodily shape like a dove upon him (v.23), being commended by the Father with "a voice [that] came from heaven," He began His ministry.
