In the coming days, in homes from Oaxaca to Los Angeles, families will clear a table, hang banners of cut paper and lay out orange marigolds. Día de los Muertos - the Day of the Dead - is observed from late October through November 2, varying by region and community, and despite the skulls it is not Mexico's Halloween. It is a homecoming.

Older than Mexico itself
The holiday's roots reach back thousands of years, to the Aztec, Maya and Toltec civilizations of Mesoamerica, whose rituals honored the dead and treated death as part of a natural cycle. After the Spanish arrived in the 16th century, those indigenous commemorations intertwined with the Catholic observances of All Saints' Day on November 1 and All Souls' Day on November 2, producing the celebration known today.
The two days have distinct meanings. November 1 - often called Día de los Inocentes or Día de los Angelitos - remembers children who have died; November 2 honors adults. Families believe the spirits of the departed return to visit during those days, and the mood is festive rather than mournful: the holiday is a celebration of life, not of death.
In 2008, UNESCO added Mexico's “Indigenous festivity dedicated to the dead” to its Representative List of the Intangible Cultural Heritage of Humanity. The tradition is kept most widely in Mexico, but it is also observed across Central and South America and, increasingly, in Latino communities across the United States.
What goes on the altar
At the center of the holiday is the ofrenda, an altar built to welcome the spirits home. Families cover it with photographs of the departed, their favorite dishes and drinks, and personal belongings. Traditionally the altar also represents the four elements: a pitcher of water to refresh the spirits after their journey, papel picado - perforated paper banners - stirring in the wind, food from the earth, and candles for fire, sometimes arranged to mark the cardinal directions.
Among the offerings is pan de muerto, a sweet bread baked for the season. Nothing on the altar is incidental: every item is placed to make the returning souls comfortable and to show them they are remembered.
The holiday's famous sugar skulls carry the same spirit. The decorated calaveras are whimsical rather than morbid - a nod to the cycle of life - and are often inscribed with the name of a loved one, living or dead.

The symbols that guide them home
The cempasúchil, or Mexican marigold, is the holiday's signature flower. Its bright color and strong scent are believed to guide spirits back to their families, and petals are laid in paths leading from the cemetery, or the front door, to the ofrenda.
The timing shows up in nature, too. Monarch butterflies arrive in Mexico for the winter around November 1, and many families believe the butterflies carry the returning souls of the departed.
Away from the altar, the celebration spills into public life: graves are cleaned and decorated, families hold vigils at cemeteries, and music and dance fill plazas. Underneath it all, the message is steady. The dead are not gone. They are expected.
