Thanksgiving is a federal holiday in the United States, celebrated on the fourth Thursday of November. It originated as a harvest festival, and to this day the centerpiece of Thanksgiving celebrations remains Thanksgiving dinner. The dinner traditionally consists of foods and dishes indigenous to the Americas, namely turkey, potatoes (usually mashed), squash, corn (maize), green beans, cranberries (typically in sauce form), and pumpkin pie. Thanksgiving is regarded as being the beginning of the fall–winter holiday season, along with Christmas and the New Year, in American culture.

Christmas (or Feast of the Nativity) is an annual festival commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world. A feast central to the Christian liturgical year, it is preceded by the season of Advent or the Nativity Fast and initiates the season of Christmastide, which historically in the West lasts twelve days and culminates on Twelfth Night; in some traditions, Christmastide includes an octave. Christmas Day is a public holiday in many of the world's nations, is celebrated religiously by a majority of Christians, as well as culturally by many non-Christians, and forms an integral part of the holiday season centered around it.
