The Super Bowl is the annual championship game of the National Football League (NFL). The game is the culmination to a regular season that begins in the late summer of the previous calendar year. Normally, Roman numerals are used to identify each game, rather than the year in which it is held. For example, Super Bowl I was played on January 15, 1967, following the 1966 regular season. The sole exception to this naming convention tradition occurred with Super Bowl 50, which was played on February 7, 2016, following the 2015 regular season, and the following year, the nomenclature returned to Roman numerals for Super Bowl LI, following the 2016 regular season. The next Super Bowl will be Super Bowl LII, scheduled for February 4, 2018, following the 2017 regular season.
