Just in time for the holiday season, FXX will once again air its “Every. Simpsons. Ever.” marathon but this time, with more episodes. Now that more seasons of “The Simpsons” are available, the event will become the longest running marathon in TV history. 

Beginning at 12 p.m. EDT on Nov. 24, the FXX marathon will run until 12 a.m EDT on Dec. 6. The 600-episode, 300-hour, 13-day long marathon will include all of the episodes from the 27 seasons of “The Simpsons.” The marathon will break the previous record which is also held by FXX when the network aired 552 episodes of “The Simpsons” in 2014.

“The first ‘Every. Simpsons. Ever.’ marathon was truly so special and landmark in its cultural relevance and impact.  The unprecedented feat of reaching 600 episodes deserves something of that caliber to mark it and celebrate it,” said FX Networks president Chuck Saftler in a statement.

The 2014 marathon gave FXX its highest ratings ever and helped propel the cable network from 49th place to 3rd in the 18-to-45 demographic during the 12-day span — a true testament to fan’s love for the series 26 years after its 1989 premiere. 

“Doing this is an act of true fandom, honoring Jim Brooks, Matt Groening, Al Jean, all the writers, artists, directors, people behind the scenes and the ridiculously talented voice actors who have brought this series to life and kept it at the pinnacle of artistic excellence these past 27-plus seasons,” Saftler said.

Season 28 of “The Simpsons” will premiere on Fox on Sunday, Sept. 25 at 8 p.m. The premiere episode, “Monty Burns’ Fleeing Circus,” will feature Amy Schumer as a guest voice. In the episode, after seeing their town burn to the ground, the Simpsons beg Mr. Burns to fund the rebuild of the town. Mr. Burns agrees but under one condition: he has to host a variety show at the Springfield Bowl.

Other guest stars for the upcoming season include Jason Alexander, Sarah Silverman, Patton Oswalt, Michael Sheen, Neil deGrasse Tyson, Ken Jennings and Drew Carey.
