And to be fair, the writer is actually trying to prove the scriptures do not contradict. But the initial contradiction is only in his understanding, so that makes the whole study mute. Thanks to everyone for all their help.

Edited for clarification:
I was referring to the nonsense of John being on "a different calendar." Matthew, Mark, and John were all Jews. The only one who is speculated to have not been a Jew is Luke (and Ray even says he was most likely a Gentile). This guy's hogwash claim that John was using a different calendar is just that - hogwash. To me, it just rang of trying to make an "epistle of straw" out of John.
Sort of as if, "Oh, John tried his best, but he was off. Don't blame him guys because he was on a different calendar, so it's not his fault. Pat him on the head, he tried." - Disgusting.
I am not trying to disparage or "strawman" Luke either. I'm merely using him as an example that even though he was probably a gentile, he even still knew precisely when the Passover was. How much more ridiculous would it be to insinuate that a Jew didn't know?
I get this feeling that this man is a wolf in sheep's clothing. He appears to be doing a "good" thing by trying to prove that the Scriptures don't contradict with the right hand, but his left is creating doubt in regards to John's writings. I wouldn't surprised if this so-called "research" is used in the future to try to create doubt in the books John wrote.
I could be wrong on this, and if I am, God will correct me. I just can't shake the feeling that this is laying the foundation for a domino effect.
