Thanksgiving is a holiday celebrated in the United States on the fourth Thursday of November where people gather with family and friends over a feast of traditional foods like turkey and pumpkin pie to give thanks for what they are grateful for. The origins of the holiday come from the first Thanksgiving in 1621 where Pilgrims shared an autumn harvest feast with Native Americans after experiencing a successful growing season. Common Thanksgiving traditions include spending time with loved ones, eating meals together, and reflecting on blessings in one's life.
