The sixth season of the American television comedy series Rules of Engagement initially received a 24-episode order and was set to debut on Saturday, October 15, 2011, but relocated to Thursdays due to the low ratings developing from How to Be a Gentleman. After CBS announced the two comedies would swap timeslots, they set the Season 6 debut as October 20, 2011 at 8:30 PM.
Effective January 12, 2012, CBS removed Rules of Engagement from its Thursday lineup, replacing it with the new sitcom Rob starring Rob Schneider. CBS announced that Rules would return to its Thursday 8:30 PM time slot at a later date. After Rob's run of its initial eight episode order, Rules returned March 29 for eight weeks of new episodes. Thus, the sixth season was cut from 24 episodes to 15.
