Not exactly.

The exact length of Jesus’ ministry is unclear from the Gospels: the Synoptics for instance mention only the last Passover in Jesus’ life. This, combined with what some see as chronological clues in Mark’s Gospel, has led some people to believe that Mark, and the Synoptics in general, portray Jesus as being in public for more or less only a single year, which they think is consistent with other prophetic figures of the period who had very short careers (before the authorities cracked down on their movements), as well as being more practical, considering Jesus’ and the disciples’ lack of formal occupations. This view, however, has two major flaws: it assumes that Mark’s sequence is chronologically correct, and not Matthew’s and Luke’s, and a literalistic reading which supposes that only the events written in Mark actually occurred. The three Gospels are known to often arrange their (episodic) material differently. Hence, to use, say, the time indicators in Mark one would have to assume that the events happened in the exact order as they appear in that Gospel. Which puts you in a dilemma if you look at Matthew and Luke: which Evangelist then represents the correct sequence? And is it not equally possible that Mark was the one who changed things instead of Matthew or Luke?
John, meanwhile, mentions three Passovers within his Gospel and a few festivals in between. In his narrative, Jesus begins His ministry apparently shortly before the first Passover and then undergoes His Passion and Resurrection in the third. A literal reading of John would infer that Jesus was in public for more or less
two years, at the least (considering that John himself admits that “
there are many other things that Jesus said and did”, more than he could write, it could be possible that he skipped some periods of time or something).
BEGINNING OF MINISTRY

ONE YEAR HAS ELAPSED
Late March-late April (Spring): Second Passover (6:4)

TWO YEARS HAVE ELAPSED
Late March-late April (Spring): Third Passover (11:55ff.)
There is, as you would mention in the impromptu chart above, a feast simply introduced by John as “
a feast of the Judaeans”. Much speculation has arisen over its identity: some have suggested Passover - which would make the total of Passovers in John into four, hence supporting the idea of a three-year ministry - others
Shavuot, aka Feast of Weeks or Pentecost, still others Purim, etc.
The idea of Jesus preaching for three (or to be more exact, three-and-a-half years) started and became popular with Origen and Eusebius, both of whom linked Daniel’s prophecy of the Seventy Weeks (9:24-27), more specifically the final half-week, to Jesus. “
And he shall make a strong covenant with many for one week, and for half of the week he shall put an end to sacrifice and offering.” Because the two reasoned that Jesus
must be the fulfillment of this prophecy (as always), then it follows that His ministry must have lasted for that duration.
Therefore it is written, ‘
and in the midst of the week shall be taken away sacrifice and libation’; (Daniel 9:27) and it is clear that with the Passion was forcibly taken from them sacrifice and libation, when according to the Evangelical Scripture ‘
the veil of the Temple was rent from the top to the bottom’ (Matthew 27:41).
