Nowadays Christmas is very different from the Christmas celebrated just aftewr Jesus' death. All Christmas is now is companies worldwide using their "True Meaning of Christmas" as a marketing ploy for money.
Also, praying is no longer the point of Christmas, and even though there is Christmas a mass on the day, it's not as important as presents. For example, on Christmas morning a boy is more likely to race to wherever the Christmas tree is and open his presents, and is less likely pray except for during mass.
