College football rankings are released at different times depending on the poll:

• The College Football Playoff (CFP) rankings are released weekly on Tuesdays during the season, starting in early November with six total rankings. The final CFP rankings come out on Selection Day, usually a Sunday in early December (for 2025, it's December 7).

• The Associated Press (AP) Top 25 college football rankings are usually released weekly on Sundays at 2 p.m. Eastern Time during the season. The preseason AP rankings are released earlier, typically on a Monday prior to the season kickoff (for 2025, the preseason AP Top 25 was released on Monday, August 11 at noon ET).

• Coaches Poll and other media rankings also follow a similar weekly Sunday release schedule during the season.

In summary, preseason college football rankings come out in early to mid- August or early September depending on the poll, and weekly rankings during the season are generally posted on Sundays at 2 p.m. ET, with the CFP rankings coming weekly on Tuesdays starting in November through early December.
