On which date was Christ born? Most Christians celebrate the birth of Christ (Christmas) on December 25. But was this really the day of Christ's birth? What was the actual date of Christ's birth?
As far as I know there is no proof of any certain date of Christ's birth. And it is only by tradition that we accept it as the 25th of December. Now I'm not one for following tradition for traditions sake, but according to this site a lot of the evidence that people provide to rule out December as Christ's birthday is not rooted in fact. I don't think the exact day is important to salvation myself, but the fact that He was born. According to the author of that site the movement to suggest he couldn't have been born in december was started by the Jehovah's Witnesses, I don't know if that's true but that's what he claims.  

The author dosen't claim that Jesus definitely was born on Dec. 25th. But claims that we just can't rule that out. Here are a couple of his points:


Those against the December date claim that it was too cold for
shepherds to be out in the field in winter; However it didn't seem to
actually get that cold in Bethlehem in December, and even if it did
shepherds would in fact stay out in the fields even in colder
weather.
Claims are made that tradition puts it in December beacause of the
pegan winter solstice, the problem with that argument is that the
winter solstice is on the 21st to the 22nd, not the 25th, and there
are thousands of pegan holidays so ANY day is some pegan celebration
in some part of the world.


So can it be proved that it was the 25th of December? No. Can it be disproved? Probably not.

Does it matter more that it happened on a certain day or just the fact that it happened?
