Does it have anything to do with Christmas?
user
Christmas is an annual Christian holiday that is celebrated on December 25th.  There are numerous reasons for the celebration of Christmas in Christian cultures.  Most of these revolve around the idea that the birth of Jesus Christ represents the arrival of salvation.  Since December 25th is the day after the solstice, it may be correlated with Jesus Christ's birth, but it is not related directly to the solstice.
