Year 4 BC was a common year starting on Tuesday or Wednesday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a common year starting on Monday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Sabinus and Rufus (or, less frequently, year 750 Ab urbe condita). The denomination 4 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Judea Province, Roman Empire
- After the death of Herod the Great, there is unrest in his kingdom. His son, Herod Archelaus becomes the new ruler of Judea. Herod Antipas becomes tetrarch of Galilee and Perea.
- The Governor of Syria, Publius Quintilius Varus, assembles three of his four legions, including Legio X Fretensis, and marched down to Jerusalem from Antioch to restore order. He crucifies 2,000 Jewish rebels.
- Jesus: Due to 4 BC being the year of King Herod's death, it is usually cited by modern Biblical literalists as being the last possible birth year of Jesus (d. circa AD 30).
According to Biblical scripture, Jesus' birthday can only be calculated by the lunar / solar calendar as described in the book of Genesis 1:14. In the Strong's Exhaustive Concordance, the word seasons is translated from the Hebrew מועדים moedim which is best translated as appointed times, holy days, or feasts. In Leviticus 23, these feasts are given in detail, and correspond perfectly with various accounts in the New Testament writings. The gospel of Luke surrenders a clear picture of the births of both Jesus and His cousin John the Baptist, giving specific Biblical months according to priestly courses and historical events. John was conceived around the Feast of Pentecost and was born around the Feast of Passover. Jesus' conception was six months after John's, around the extra biblical feast of Hanukkah and was born around the Feast of Tabernacles. Another word for Tabernacles used in multiple translations of the Bible is manger. And the Word became flesh, and tabernacled among us, and we beheld His glory, glory as of the only begotten of the Father, full of grace and truth.
