The origins of Christmas in America can be traced back to the arrival of European settlers in the 17th century. The holiday was initially observed as a religious celebration by Puritans and other Christian groups, who marked the day with church services and family gatherings. Over time, the celebration of Christmas began to incorporate secular traditions, such as gift-giving and seasonal decorations. Today, Christmas is celebrated widely across the United States, with Christmas trees, Santa Claus, and other familiar elements playing a central role.
