The actual birthdate of Jesus was Sept 11, 3 BC.
Many readers will know that I believe the actual birthdate of Jesus was Sept 11, 3 BC. This isn’t based on any original research of my own (here’s a short YouTube video of me discussing the date). Rather, it is based on the work of E. L. Martin’s The Star that Astonished the World (which can be read for free). Most academics are unaware of Martin’s research because he wasn’t a member of the biblical studies guild. Others reject it out of hand because of Martin’s involvement with the old Worldwide Church of God. The quality of one’s research, however, doesn’t depend on having a PhD in biblical studies or whether one is doctrinally correct in all areas. I don’t buy Martin’s views on other things, but I find his work on the birth of the messiah persuasive (and it has a long history of endorsement in planetariums).
