Día de los Muertos is a communal celebration of life that predates Hispanic invasion and consists of two days - November 1st and 2nd. It honors deceased loved ones whose souls are believed to return to Earth to celebrate with the living. Families set up altars and decorate gravesites with favorite items and flowers to welcome the souls back and guide them home. Traditions vary but include lighting candles in cemeteries to protect souls and remember lives that have passed through seasonal foods, masks, and sweets.
