How Dia de los Muertos is celebrated in Mexico

“It is a purely Catholic tradition that the Spaniards bring to Mexico and merges with the entire worldview or form of Mesoamerican thought. It is a festival that gives us belonging and unites us,” Martínez said.Popular beliefs vary depending on the Mexican region. Apart from Nov. 1 and 2, Oct. 28 is celebrated for those who died tragically or accidentally, and Oct. 30 is dedicated to those who died without being baptized and are in limbo.
