The Day of the Dead originates from the ancient cultures of the (Aztec), (Toltec), and other (Nahua) peoples. For these cultures, grieving the dead was seen as disrespectful and unnecessary because death was viewed simply as a part of the life cycle, a journey that everyone must undertake. Those who have passed away would forever remain alive in the memories and spirits of the living.
The modern Day of the Dead in Mexico, shaped by Spanish colonization, merges Catholic religious rituals and celebrations (akin to Western Halloween and All Souls' Day) and is celebrated on November 1st and 2nd each year. November 1st is referred to as "Día de los Inocentes" (Day of the Innocents), a day to remember children, while November 2nd is "Día de los Muertos" (Day of the Dead), which honors adults. It is believed that during this time, the spirits of the deceased return to the world of the
living. This day is also a time for families and friends in Mexico to come together and pray for the deceased. Traditional memorial practices include setting up personal altars adorned with sugar skulls, marigolds, and foods that the departed enjoyed in life, and bringing these offerings to the cemetery to honor the deceased.
