After building a reputation strictly through promotion on the social networking website MySpace, the band released its debut self-titled EP in 2006 and their first full-length album My Dear in 2007.

Meeting with lead vocalist Ashley "Ash" Costello (born 1985) and guitarist/keyboardist Keith Drover, the three friends wrote and rehearsed songs about their difficult and emotional relationship break-ups.

[4] After acquiring former Wakefield guitarist Mike Schoolden and drummer Russell Dixon, the group decided to call themselves New Years Day.

New Years Day was featured on the MySpace Records, Volume 1 compilation CD and on the video game soundtrack for Saints Row.

Originally referred to as Razor, the EP was primarily marketed as a digital release accessible through downloading services, although CD hard copies were also sold to fans at live shows.

[5] By May 8, 2007, New Years Day released its debut album My Dear, which was self-financed, self-produced and recorded over an eight-month period by friend and producer Eugene Perreras.

During this period of time, the band toured with fellow artists, The Fall of Troy, The Red Jumpsuit Apparatus, Ozma and Hawthorne Heights.

Headlines & Headstones included music from New Years Day, My Dear, new songs from their upcoming sophomore U.S. album and even a cover of Lady Gaga's Bad Romance.

[13] Nikki Misery joined the band on this tour as its lead guitarist, replacing Matthew Lindblad who pursued a solo career.

[19][20] When asked about the new EP, Costello commented in an Alternative Press interview, "We've taken what we have experienced in the past year and a half and poured it all into these new songs...

Just before the tour, Anthony Barro left the band to pursue a career in sound engineering and in turn, Burgess moved from guitar to fill the bass position.

On the eve of the album's release, New Years Day held a YouNow streaming chat with fans to celebrate the completion of Malevolence.

[28] The band also headlined the 2017 Vans Warped Tour alongside other main stage acts like Bowling for Soup, Falling in Reverse and CKY.

[29] On June 1, 2017, it was announced they would be included in the seventh installment of the Fearless Records compilation Punk Goes Pop, covering Kehlani's "Gangsta" from the movie Suicide Squad.

After completing a month-long festival run with Halestorm on the 2017 "Halloween Scream Tour", both Valentyne and Ingram quietly parted ways with the band.

In early February 2019, Costello stated that Unbreakable's sound will be significantly heavier than Malevolence, and thematically, will focus more on empowerment, and less on the negativity and self-pity of past albums.

At night two of WWE WrestleMania 37, New Years Day performed live Rhea Ripley's theme song Brutality as she made her entrance to the ring.
