The band was formed in mid-2002 by guitarist Aaron Bilbija, bass player Meredith Webster and drummer Matt Lamb. All three had previously been together in a thrash metal band called Psi.Kore that had been founded by Lamb's brother Chuck in 1996; Lamb had joined in 1997 and Webster in late 1998. The band recorded an EP with Chatterbox Records in 2000 and toured Australia widely before Bilbija was recruited in early 2002. Relations within the group pushed Chuck Lamb out and the remaining members decided to continue in a slightly different musical direction. In 1995 Bilbija had formed a death metal band called Deadspawn and with the eventual line-up of himself plus Dave Micallef (vocals, guitar), Bob Latsombath (bass) and Wayne Morris (drums) that group had released an album on Warhead Records in 1999 before eventually splitting up when Micallef left in mid-2001. Bilbija now recruited Micallef into his latest band, and Daysend was formed with guitarist Michael Kordek (from a death metal act called Automation and then, briefly, Infernal Method with Bilbija) also coming into the group[2]. The line-up was only together briefly before Matt Lamb left, his place taken by Morris. Lamb played in some local rock acts for a short time before essentially quitting music.

A debut live show with Melbourne death metal band Earth was booked but Micallef quit Daysend before the show; the band played regardless as an instrumental act. Inheriting Psi.Kore's manager, Chatterbox owner Nik Tropiano, who had helped push that group to the verge of major success, Daysend was listed on the bill for the 2002 Metal for the Brain festival and slated to open for Austrian extremists Pungent Stench shortly afterward, both without so much as having either a recording or a vocalist. However, Metal for the Brain was cancelled due to an insurance cost blow-out and Daysend had still not found a singer in time for the Pungent Stench tour. In January 2003, Simon Calabrese was recruited as lead vocalist. Calabrese had previously been with a nu-metal act called Redsands that had recorded an EP before disbanding.

With Calabrese in place, Daysend immediately found themselves supporting Sweden's The Haunted in March and then on a national tour with the reformed Melbourne grindcore band Damaged. After this Daysend spent ten days recording the debut album Severance which was released by Chatterbox in October. Severance was voted Best Australian Metal Album in a Triple J listeners poll soon after, an honour it shared with Renascent Misanthropy by Brisbane black metal band Astriaal.

2004 saw Daysend touring heavily. They supported Slipknot, In Flames, Shadows Fall and Machine Head and toured nationally with Entombed. Severance was released in the US by Metal Blade Records and by Locomotive in Europe in November. When the Metal for the Brain festival added two extra shows in Brisbane and Perth along with its regular Canberra fixture in February 2005, Daysend appeared at each. Two days before this, however, Kordek suddenly left the band. His replacement was Andrew Lilley, who had most recently served a brief spell with Melbourne thrash band Atomizer. Lilley's addition to Daysend caused some initial surprise as he had been fired from Psi.Kore in mid-2001, then coincidentally joined Infernal Method after Bilbija had left to join Psi.Kore. However, after learning the band's entire set in one emergency rehearsal, he slotted into the Daysend line-up.

In May 2005, Daysend toured the US for six weeks with Otep. On returning to Australia, the band split with both its management and with Lilley. Michael Kordek rejoined and some work began on a second album. Further activity was stalled however when Simon Calabrese left Daysend in May 2006. Within a short time, however, ex-Headcage vocalist Mark McKernan joined the band. Playing just two shows with him, Daysend began recording The Warning in November 2006 with DW Norton, who had also produced the debut. Norton signed the band to his label Faultline and the album was released on May 28, 2007 ahead of Daysend's appearance at Sydney's two-day Come Together Festival. A national tour began soon after but at least one show was cancelled when Morris received an eye injury from a broken drumstick during a show in Sydney on 13 July. He has since recovered.
