Each NFL team plays 16 games over the 17-week season. The league uses a formula to determine all 256 matchups. The leagueâs 32 teams are split into two conferences â the American Football Conference (AFC) and the National Football Conference (NFC).
Each NFL team has one bye week during a normal season; this is placed on the team's schedule between Week 4 and Week 12. The NFL has used the bye week since 1990 so as to extend the 16-game regular season schedule to span 17 weeks. The 1993 NFL season spanned 18 weeks with each team having 2 bye weeks.
