Jesus was definitely NOT born on 25 December.
An extract of one of the many web links on this controversial matter gives -
Jesus was NOT born on 25 December.
The approximate month of Jesus’s birth is estimated to be around the time of Tishri (mid to late September). To arrive at this date, start at the conception of John the Baptist, Sivan (June), count forward six months to arrive at Gabriel’s announcement of the conception of Jesus, Kislev (December), then count forward nine more months, the time it takes for human gestation, to reach Tishri (September), when Jesus was born in or around 2 BC.
The date and time of Jesus's birth is unknown and the Bible was written 50 + years after his death.
Absolutely nothing is factual, simply hearsay and circumstantial.
Comments are welcome.
