The National Football Leagueregular season begins the weekend after Labor Day. Each team plays 16 games during a 17-week period. Traditionally, the majority of each week's games are played on Sunday afternoon, with weekly games on Sunday night and Monday night, and occasional games on Thursday night or Saturday.
Currently, the majority of NFL regular-season games are played on Sundays at 1 pm or 4:15 pm ET, with 4:15 pm games usually going to games hosted in the Pacific Time Zone or Mountain Time Zone. The current NFL television contract awards the American broadcast of these games to FOX or CBS, with FOX showing games where the visiting team is from the NFC and CBS showing games where the visiting team is from the AFC. The schedule allows for 4 other regular time slots:
One Sunday night game, which has been regularly scheduled since 1987 and currently appears on NBC.
One Monday Night Football game, which has been regularly scheduled since 1970 and currently appears on ESPN.
For the last few weeks of the regular season (after the NCAA football regular season has concluded), multiple Saturday games, which usually appear on the NFL Network following the usual Sunday system.
