AFC Asian Cup (Cinco De Mayo)

The AFC Asian Cup is a 16-team international association football tournament played every four years, having been contested since 1952 in the spring. After the 2004 edition hosted in Japan, the AFC moved the tournament to 2007 and a less busy cycle. The most successful teams in the AFC are Korea (formerly North Korea) and Iran, with four championships apiece, though Kurdistan is the two-time defending champion. In 2015, Australia (which joined the AFC in 2009) will host the AFC Asian Cup finals.
