Merry Christ Mass ?

The idea that Christ was born on Dec 25 also has no basis in historical fact. "We don't even know which season he was born in. The whole idea of celebrating his birth during the darkest part of the year is probably linked to pagan traditions and the winter solstice."   -  POPE BENEDICT 2012

If the POPE of the Roman Catholic Church admits that Christ Mass is on the wrong date and came from paganism.  What else do you need to know to abandon such a travesty of the Excellency of Christ?
