'Year' in the Bible

But one of them, Caiaphas, who was the high priest that year [the year of Christ’s crucifixion], said to them, “You know nothing at all!

Now he did not say this [simply] on his own initiative; but being the high priest that year, he [was unknowingly used by God and] prophesied that Jesus was going to die for the nation,

and led Him to Annas first; for he was the father-in-law of Caiaphas, who was high priest that year.
