The birth of this child in Revelation 12 (whom John identified with Jesus) should have occurred while the Sun was “clothing” the woman, when the Sun was mid-bodied to Virgo. This period of time in 3 B.C.E. covered 20 days (August 27 to September 15). If Jesus were born within that 20-day period, it would fit most remarkably with the testimony of Luke (relative to the birth of John the Baptist and the eighth course of Abijah). Indeed, the chronological indications associated with the priestly course of Abijah place Jesus’ birth exactly within this period. But there is a way to arrive at a much closer time for Jesus’ birth than a simple 20-day period. The position of the Moon in John’s vision actually pinpoints the nativity to within a day ― even to within a period of an hour and a half (within 90 minutes) on that day. This may appear an absurd assessment on the surface, but it is quite possible.
The key is the Moon. The apostle said it was located “under her feet.” What does the word “under” signify in this case? Does it mean the woman of the vision was standing on the Moon when John observed it or does it mean her feet were positioned slightly above the Moon? John does not tell us. This, however, is not of major consequence in using the location of the Moon to answer our question because it would only involve the difference of a degree or two. The Moon travels about 12 degrees a day in its course through the heavens. This motion of one or two degrees by the Moon represents on earth a period of only two to four hours. This difference is no problem in determining the time of Jesus’ birth. What is vital, however, is that this shows the Moon as a New Moon.
