There seems to be diverse opinions about the length of time of Jesus's ministry. And, that depends upon the opinions of the scholars and what sources they are referencing and what point they are trying to prove.
That whole discussion is on par with arguing about how many angels can dance on the head of a pin.
2000 years later it really doesn't matter. What does matter is that Jesus did live and what he taught while walking the earth and what he is teaching all of us, now.
The 3.5 year ministry was solely the creation of Eusebius.
Prior to his mischief, it was commonly held that Yeshua’s ministry was about one year. Eusebius added the words of John 6:4 to the Bible to stretch the length of Yeshua’s ministry, but failed to consider that the words he added would be far beyond anything a real Jew like John would write about one of the chief prophecies of the entire scriptures, and the literal key to salvation.
