Week 0

Week 0 refers to the opening weekend of college football games in the 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”. 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, usually away games against the Rainbow Warriors, an extra regular season home game to offset travel costs. Games in Alaska, Puerto Rico and other outlying territories would nominally count towards the Hawaii Rule, but those locales do not field FBS programs, or have venues that met NCAA minimum attendance guidelines before those were abolished in 2023.
