The "Day of the Dead" celebration takes place every year on the days when Halloween fills the streets and shops of many countries in the world with pumpkins, ghosts and scary costumes. Despite the proximity in time and the presence of skulls and skeletons in both, "Day of the Dead" is not Mexican Halloween; This is another ceremony that commemorates the deceased, their symbolic return home and the continuation of the connection between the living and the dead. Traditions of commemorating the dead existed among several Native American cultures, and after the arrival of the Spanish, it became mixed with the Catholic observance of All Saints' Day. For families, one of the most important parts of the ceremony is the construction of the operanda, the memorial altar for the deceased. On these altars are placed the picture of the deceased, his favorite food and drink, candles, water, bread for the dead, colored papers and flowers. In some areas families go to the cemetery and clean and decorate the graves. Yellow and orange marigolds are one of the most important signs of this ceremony. Families use its petals to create a path between the entrance of the house and the altar; show the way back to the spirits. Harrier butterflies are also associated with the spirits of the dead in certain local beliefs, as their annual migration arrives in Mexico almost at the same time as the Day of the Dead. Face makeup in the shape of a skull, colorful clothes, candles, flowers and the image of "Katrina" have also become in recent decades the most well-known visual symbols of this celebration. The global expansion of the images of the Day of the Dead and its proximity to Halloween have made Mexicans and many Mexicans living in other countries emphasize the independent identity of this ritual. This year, the main days of this ceremony are Sunday and Monday, November 1 and 2, 2026 (November 10 and 2, 1405), although in many areas of Mexico the ceremony begins a few days earlier.
