"The Day of the Dead" was released to PBS Kids' website and video on October 22, 2018. In the United States, the episode premiered on November 21 on both PBS Kids at 2:30 PM ET and on the 24/7 channel and re-aired on November 22 at 5:00 PM ET for the same purpose.
During Día de Muertos, the tradition is to build private altars ("ofrendas") containing the favorite foods and beverages, as well as photos and memorabilia, of the departed. The intent is to encourage visits by the souls, so the souls will hear the prayers and the words of the living directed to them. These altars are often placed at home or in public spaces such as schools and libraries, but it is also common for people to go to cemeteries to place these altars next to the tombs of the departed.
