Day of the Dead (Día de Muertos) is a Mexican holiday celebrated throughout Mexico and around the world in many cultures. The holiday focuses on gatherings of family and friends to pray for and remember friends and family members who have died. It is particularly celebrated in Mexico, where it attains the quality of a National Holiday, and all banks are closed. The celebration takes place on November 1–2, in connection with the Catholic holidays of All Saints' Day (November 1) and All Souls' Day (November 2). Traditions connected with the holiday include building private altars honoring the deceased using sugar skulls, marigolds, and the favorite foods and beverages of the departed and visiting graves with these as gifts.
In most regions of Mexico, November 1 honors children and infants, whereas deceased adults are honored on November 2. This is indicated by generally referring to November 1 mainly as Día de los Inocentes ("Day of the Innocents") but also as Día de los Angelitos ("Day of the Little Angels") and November 2 as Día de los Muertos ("Day of the Dead")
Plans for the day are made throughout the year, including gathering the goods to be offered to the dead. During the three-day period, families usually clean and decorate graves;] most visit the cemeteries where their loved ones are buried and decorate their graves with ofrendas (offerings), which often include orange Mexican marigolds. These flowers are thought to attract souls of the dead to the offerings.
Toys are brought for dead children, and bottles of tequila, mezcal or pulque or jars of atole for adults. Families will also offer trinkets or the deceased's favorite candies on the grave. Ofrendas are also put in homes, usually with foods such as candied pumpkin, pan de muerto ("bread of the dead"), and sugar skulls and beverages such as atole. The ofrendas are left out in the homes as a welcoming gesture for the deceased. Some people believe the spirits of the dead eat the "spiritual essence" of the ofrendas food, so even though the celebrators eat the food after the festivities, they believe it lacks nutritional value. Pillows and blankets are left out so that the deceased can rest after their long journey. In some parts of Mexico, such as the towns of Mixquic, Pátzcuaro and Janitzio, people spend all night beside the graves of their relatives. In many places, people have picnics at the grave site as well.
Those with a distinctive talent for writing sometimes create short poems, called calaveras ("skulls"), mocking epitaphs of friends, describing interesting habits and attitudes or funny anecdotes. This custom originated in the 18th or 19th century, after a newspaper published a poem narrating a dream of a cemetery in the future, "and all of us were dead", proceeding to "read" the tombstones.
The traditions and activities that take place in celebration of the Day of the Dead are not universal and often vary from town to town.
