From here in the U.S., the perspective on this question is twofold. Firstly, Christmas, Hanukah, Kwanza and New Years are all folded into a generic "Happy Holidays"... add to this the second aspect of Christmas having become the most commercialized "holiday" of the year and an attempt (at least seen by many) of de-Christianizing the season in the hope of prospering P.C.
The shopping season for Christmas actually begins the Friday following Thanksgiving (4th Thursday of November) known as "Black Friday" in that many businesses will either end the year in the red or in the black depending on sales. This aspect of Christmas reigns over nearly the entire month of December. (We don't, by the way, observe "Boxing Day as does the U.K. and our friends to the North).
To the point of Christmas having been a pagan festival... could be true, since it's relatively close to the Winter Solstice (December 21) but no where in the New Covenant of the Bible are we reminded to remember or celebrate the birth of the Savior... only His death, burial and resurrection.
"Despite its popularity today, this theory of Christmas’s origins has its problems. It is not found in any ancient Christian writings, for one thing. Christian authors of the time do note a connection between the solstice and Jesus’ birth: The church father Ambrose (c. 339–397), for example, described Christ as the true sun, who outshone the fallen gods of the old order.
