Thanksgiving is an annual holiday celebrated in the United States and Canada that originated as a harvest festival, with the main American observance falling on the fourth Thursday of November. It centers around gathering with family and friends for a feast that traditionally includes turkey, stuffing, cranberry sauce, mashed potatoes, and pumpkin pie. The modern Thanksgiving is traced back to a 1621 celebration shared between the English colonists of Plymouth and the Wampanoag people. In the days following, Americans partake in leftovers and Black Friday shopping events with large discounts.
