The second season of the American television series Bones premiered on August 30, 2006, and concluded on May 16, 2007, on Fox. The show maintained its previous time slot, airing on Wednesdays at 8:00 pm ET for the entire season. The season consisted of 21 episodes and averaged 9.4 million viewers.

The third season of the American television series Bones premiered on September 25, 2007, and concluded on May 19, 2008, on Fox. The show moved back to its original time slot, airing on Tuesdays at 8:00 p.m. ET before moving to Mondays at 8:00 p.m. ET in 2008. Although a full slate of 20 episodes were produced, the 2007–2008 Writers Guild of America strike interfered with the writing of Season 3, and the network rearranged the broadcast schedule to compensate. One episode from the second production season, "Player Under Pressure", was moved to the third broadcast season, and six episodes from the third production season were moved to the fourth broadcast season. Due to this rearrangement, the show had an extended hiatus after "The Santa in the Slush" aired on November 27, 2007; the show returned on April 14, 2008. The season averaged 8.9 million viewers.
