University Athletic Association of the Philippines
Beginning Season 78, the league has shifted its sports schedule start from September to December because of the change in the academic calendars of most of its member universities.
A rivalry between the Ateneo de Manila and the University of the Philippines existed even before the formation of the NCAA-UAAP. UP students would troop from Padre Faura to the Ateneo campus in Intramuros to play basketball with the Ateneans, which led to Ateneo forming the first organized cheering squad and pep band in the Philippines and what is now known as the Blue Babble Battalion. This would later become "UAAP's Battle of Katipunan" when both universities transferred to their respective campuses along Katipunan Avenue in Quezon City, and when the two schools began competing in the UAAP. UP and Ateneo currently holds first and second spots, respectively, in the Philippines' nationwide academic rankings.
