Week 0 (or Week Zero) refers to the opening weekend of college football games in NCAA Division I Football Bowl Subdivision (FBS), in which a small number of games are played to begin the regular season, a week before the vast majority of teams begin their season in "Week 1".[1][2][3] Although the FBS football season has traditionally begun on the first Saturday before Labor Day, the NCAA has sporadically awarded waivers for games to be played a week earlier in order to bring a game to a national television audience, or as part of the "Hawaii Rule" that grants teams that play a game in Hawaii an extra regular season home game to offset travel costs. The first Week 0 game was the 1983 Kickoff Classic, in which No. 1 Nebraska defeated No. 4 Penn State, 44–6, at Giants Stadium in East Rutherford, New Jersey.[4]
For the 2020 season, the NCAA issued a blanket waiver for Week 0 games by any team, in order to allow for scheduling flexibility amid the COVID-19 pandemic.[5] However, no Division I FBS members wound up playing in a Week 0 game in 2020.
