Day of the Dead

The Day of the Dead — or Los Muerte Dos Dios — was a Mexican holiday celebrated on 2 November that Frida Kahlo said stretched back to the time of the Aztecs. Izzy said the name sounded like a zombie movie. (COMIC: The Way of All Flesh)

The Tenth Doctor first met Gabby Gonzalez on 30 October, during the preparations for the Day of the Dead celebrations in Brooklyn. That year the local councillor Ricardo Mendoza has obtained a permission to hold a festival at Green-Wood Cemetery, which was interrupted by a Cerebravore invasion. (COMIC: Revolutions of Terror)

The Eleventh Doctor tried to take Amy and Rory to see the Day of the Dead festival but the TARDIS instead brought them to Mercy, Nevada. (TV: A Town Called Mercy)
