Man that profits from a film being a Xmas film says it's a Xmas film shock. Unless he said it in the 80s before it was released then it clearly was never intentionally a Xmas film.
It was an action film that used Xmas as the reason McClane was in the building. Xmas is a McGuffin.
Look how Xmassy the poster was. It doesn't even mention Xmas.

People have convinced themselves it is a Christmas movie. At first it was an ironic joke around 2009, before then there was no talk of it being a Xmas film. It snowballed (pun intended) and now people watch it at Xmas. If that makes it a Xmas film then fine but it is clear that there was never any intention for it to be one. It's just a joke that got out of hand. It's a great film, I'd watch it at any time of the year which is another reason it's not really a Xmas film.
