FXX is planning 12 days that will put that Christmas song to shame.

This summer, the FXX network will launch "The Simpsons" in style with a 12 day marathon, showing all 552 episodes consecutively. The marathon will start August 21st and continue through Labor Day.

“It will be the longest continuous marathon in the history of television," said chief executive of FX Networks Jon Landgraf at an upfront presentation held in New York on Wednesday, reported Variety.

In addition to the marathon, FXX will make use of their $750 million dollar investment by showing four hours of episodes every Sunday this fall.
