when did this christmas come out

Christmas is a holiday with roots dating back over 4,000 years, originating in the winter solstice celebrations of various cultures. The modern holiday of Christmas, as we know it today, began to take shape in the 4th century AD under the Roman Empire. In 350 AD, Pope Julius I established December 25th as the official date for Christmas to coincide with the pagan holiday of Saturnalia. The tradition of gift-giving on Christmas can be traced back to the 14th century, when Saint Nicholas is said to have left gifts for three poor children.
