Día de los Muertos is a holiday rooted in Pre-Columbian Meso-American traditions and the observance of All Souls’ Day brought to Mexico by the Spanish in the early 1500s. It is celebrated on November 1 and 2, with preparations happening in the days beforehand. The holiday centers on family remembrance, with homes and cemeteries decorated with altars and ofrendas (offerings) for the spirits of loved ones who have passed away.
