The annual event held in the United States to celebrate Thanksgiving is Thanksgiving Day, which occurs on the fourth Thursday of November. This holiday has historical roots in the early 17th century, when Pilgrims and Indigenous Americans shared a harvest feast, marking a moment of gratitude. Today, Thanksgiving is characterized by family gatherings, feasting on traditional foods such as turkey, stuffing, and pumpkin pie. It serves as a time for reflection and appreciation, with many Americans also observing practices of volunteering and giving to those in need. The celebration has evolved but remains a cherished tradition across the country.
