To date (October 2008), The Disney Channel has only broadcast two marathons of Phineas and Ferb: Phineas and Ferb-uary and Spot the Diff.

Phineas and Ferb-uary was a promotion that Disney Channel ran during the month of February 2008. An episode was broadcast on each of the 29 days during that Leap Year month. Seventeen episodes debuted during this time, with a possible eighteenth episode (Ready for the Bettys), according to The Internet Movie Database. Phineas and Ferb-uary served as the official kick-off for the series, even though Rollercoaster and Lawn Gnome Beach Party of Terror were first broadcast in 2007 (8/17/2007 and 9/28/2007, respectively).

Spot the Diff was a mini-marathon that premiered at 8 p.m. on August 8, 2008 (8/8/08). The premise was that Dr. Doofenshmirtz had created a "Change-inator-inator" that was capable of altering an episode, such as making people or things appear that hadn't previously, or giving Phineas star-shaped sunglasses when he hadn't been wearing any sunglasses before. A scorecard was available on the Spot the Diff website that viewers could use to keep track of the changes. If the viewer answered enough questions correctly, they could watch two episodes on the Disney website that had not yet been shown at that time.
