Wake Me Up When September Ends is about the death of Billie Joe Armstrong's father.
 Armstrong has expressed his displeasure with the memes and has joked about wanting to write a sequel song in response called "Shut the Fuck Up When October Begins"
 In the United States, the song became symbolic after Hurricane Katrina, where it was dedicated to victims of the disaster, and also regarded as a dedication to the victims of the September 11 attacks that occurred in 2001
