The time lines are the years that they were high priest. One had to be at least 30 to be a priest and I assume a few years on the job to learn the ropes and get the gelt to buy the position from Rome and some reputation with the other priests. You can find some history here;

Interesting, the last you hear of Caiaphas is Acts 4:6 with his son, Annas, the next high priest but no mention of his father, Annas, as was the case with the trial of Jesus. In fact there is no mention of the high priest by name after Acts 4.
Oh Well — he missed a good show. Too bad.
