Days Go By's lead single and title track was premiered on radio stations on April 27, 2012, and was released to digital outlets.

"Cruising California (Bumpin' in My Trunk)" was the first single from the album worldwide (except for the United States, Canada, Germany, Austria and Switzerland), and was released on April 30, 2012.

[8] While touring in support of Rise and Fall, Rage and Grace, The Offspring began to write new material in 2009 for what would become Days Go By.

In a May 2009 interview, Noodles revealed that frontman Dexter Holland had been working with producer Bob Rock, and mentioned that the album would include songs that did not appear on Rise and Fall, Rage and Grace.

[9] A month later, Holland told OC Register that he wanted to try not to have the ninth Offspring record take as long as Rise and Fall, Rage and Grace.

During that tour, they debuted a new song, titled "You Will Find a Way", at The Joint at Hard Rock Hotel, Las Vegas on June 18, 2010.

[13] On May 3, 2010, Holland posted an update on the new album on the message board of the official Offspring website saying that the band was "working on a batch of songs.

He also revealed that the band had been in the studio working on the album "every day for the next two weeks...we're going to try to get something new finished and ready to play live on tour this summer."

[15] On December 20, The Offspring stated on their Twitter that they had spent the last 2 weeks in the studio and they would continue recording their new album after the holidays for 2011 release.

We're taking a little break because I need to write some lyrics...I'd say we have a good chunk of the music recorded...we've got 12 songs we like and I think all the drums are done, we've got a lot of guitars...it's just getting the vocals together.

"[20] On September 14, 2011, The Offspring announced on their Facebook page that they were expected to "be back in the studio in about a week" to restart recording their new album, which they hoped would be finished within the next two or three months.

On June 19, 2012, a week before its release, the band announced via Twitter that Days Go By was streaming on Rolling Stone magazine's website.
