Day of Attis' death, pre-Christian sacred calendar = "Black Friday," the original day of mourning before Easter
The Connection
The day of Attis' death in the Cybele cult was celebrated as a day of mourning and fasting, falling on what would later become Good Friday in the Christian calendar. The UB connects this pre-Christian "Black Friday" to the later Christian observance, showing how the existing ritual calendar was absorbed rather than invented from scratch.

Historical Evidence(Strong evidence)
The UB explicitly connects the Attis mourning day with the Christian Good Friday observance. Jaime Alvar documents the March festival of Cybele/Attis: March 22 (tree-bearing), March 24 (dies sanguinis/day of blood, when Attis dies), March 25 (hilaria/day of joy, when Attis rises). This three-day death-and-resurrection sequence, celebrated in Rome centuries before Christianity, provided a ready-made ritual template. The calendrical correspondence is well-documented in Roman religious scholarship.
