What, you don’t know what Dia de Los Muertos is? You mean you don’t have an altar to remember those who have passed?
Wikipedia explains that Day of the Dead or in Spanish: Día de Muertos “is a Mexican holiday observed throughout Mexico and around the world in other cultures. The holiday focuses on gatherings of family and friends to pray for and remember friends and family members who have died.”
“The celebration takes place on October 31, November 1 and November 2, in connection with the triduum of Allhallowtide: All Hallows’ Eve, Hallowmas, and All Souls’ Day.[2][3] Traditions connected with the holiday include building private altars called ofrendas, honoring the deceased using sugar skulls, marigolds, and the favorite foods and beverages of the departed, and visiting graves with these as gifts. They also leave possessions of the deceased.”
