Jesus Christ Was Born on 21 September 5 BC

When was Jesus Christ born? The New Testament contains the information which allows to find out real date of a birth of Jesus Christ. Many researchers tried to make it. I have own version. This version is stated in my book Astro-Biblos (Russia, St. Petersburg, 1996). Basing on facts that Zoroastrianism had influence on the Qumrans Scrolls of the Essenes (precursors of Christianity) and analyzing Gospels from this point of view, learning upon the ancient Zoroastrian calendar, I have established the real date of birth of Jesus Christ. He was born on 21st September 5 BC.
