Several Herods during this time period i would think it was his son Herod Archelaus ethnarch of Judea, Samaria, and Idumea (biblical Edom) from 4 BCE to 6 CE thay is being referred to.<quoted text>
A monk devised the calendar back in the 6th century. Somehow he made some miscalculations.
Its been known for centuries that there was conflict in the gospel of Matthew and Luke as ot the birth of Jesus.
Matthew claims that the birth of Jesus occurred during the reign of Herod the Great of Judea, whom we know died in 4 B.C.
Luke also tells us that Jesus' birth happened during Herod's reign. Luke even adds what appears to be detailed and historical evidence of the period. He writes that Jesus was born during a census or registration of the populace ordered by emperor Augustus at the time that Quirinius (Cyrenius) was Roman governor of Syria (Luke 2:1-3). In reality, this has to be a fabrication because Quirinius was not governor of Syria and Judea during Herod's kingship. Direct Roman rule over the province of Judea, where Bethlehem was located, was not established until 6 A.D. In other words, ten years separated the rule of Quirinius from Herod.
If the census did take place, it was in the year 6 CE, long after Herod's death. Therefore, Matthew's stories of the Wise Men's visit to Herod and the Christchild, and Herod's massacre of the innocents which caused the holy family to flee to Egypt, are all historically impossible. Moreover, it should be noted that Luke also got his facts wrong about the census of Augustus. Such an imperial census would only apply to Roman citizens of the empire, not to Joseph, a Galilean who was not under direct Roman rule.
...something is terribly wrong!
The Romans made Herod's son Herod Archelaus ethnarch of Judea, Samaria, and Idumea (biblical Edom) from 4 BCE to 6 CE, referred to as the tetrarchy of Judea. Archelaus was judged incompetent by the Roman emperor Augustus who then combined Samaria, Judea proper and Idumea into Iudaea province under rule of a prefect until 41. Herod's other son Herod Antipas was tetrarch of Galilee from 4 BCE – 39 CE.
