Day of the Dead (Día de los Muertos) is observed in Mexico and regions with large Hispanic populations every November 1 and 2. This two-day holiday coincides with All Saints' Day and All Souls' Day, while also incorporating traditions from pre-Christian times, where celebrations dedicated to deceased ancestors were held. The festival has historical roots linked to the worship of the goddess known as the Lady of the Dead, which evolved into the modern symbol of La Calavera Catrina, a female skeleton. Typical customs include building private altars (ofrendas) for the deceased, adorned with their favorite foods, beverages, sugar skulls, photos, memorabilia, and Mexican marigolds. Additionally, it is customary for families to visit cemeteries to clean and decorate graves. In 2008, UNESCO recognized the Day of the Dead as part of the Representative List of the Intangible Cultural Heritage of Humanity.
