Jesus was almost certainly NOT born on December 25th.
That being said, the peculiar beliefs of Jehovah's Witness have developed over the last couple of centuries. As different individuals have taken control of the organization over time, they each have made significant changes in doctrines, practices and "beliefs" in order to create a religion in their own image.
Charles Taze Russell, as misguided as he was, likely actually believed he was discovering (or perhaps "rediscovering") revealed truth. In his time they celebrated Christmas.
After he died, Joseph Rutherford, who was an opportunist and a bully, drastically altered the religion, again morphing it into his own image. As a lawyer (of questionable credentials) he transformed the religion into the highly legalistic entity it is even to this day.
From Rutherford's time until now the emphasis has been on being different and unique. The Bible, while omnipresent, has largely been a mere prop to lend credibility to their doctrines and beliefs.
Oddly, the current Governing Body of Jehovah's Witnesses has recently made changes that superficially make the religion appear more mainstream. Although they still don't celebrate Christmas and they will disfellowship you for openly criticizing the WT leadership, they now have their very own TV show very much like the 700 Club and a myriad of other televangelists.
Oh, and they need your money. Lots of it!
Let's review: It's a cult!
