The easiest way to find kickoff times for all televised football games is to visit TVGuide.com and check the football games being aired each week in your market. Kickoffs of regular season games typically take place just minutes after the listed broadcast start times.
TVGuide.com typically posts the most comprehensive list of pro and college football games being televised across all providers in your area. The one exception to this rule is what is known as Sunday flex scheduling in the NFL. To ensure a better matchup on nationally-televised Sunday night games, the league reserves the right to move a Sunday afternoon kickoff into the evening time slot. The NFL must announce a flex schedule change no later than 12 days before the scheduled game.
TVGuide's online listings for football normally have scheduled start times for NFL and college games listed more than a month in advance. You can also see start times for any pro game at the league's website at NFL.com.
