Very likely. Not, of course all that important when we celebrate as long as we do. I did see a presentation once that made a good case that the star shining on Bethlehem that led the wise men there was on December 25.
But whatever...
`Twas brillig, and the slithy toves
Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.
