DAY6

DAY6 began in 2014 as a five-member pre-debut act called 5LIVE, formed by JYP Entertainment, consisting of Sungjin, Jae, Young K, Junhyeok, and Wonpil. With the addition of drummer Dowoon in 2015, the lineup expanded to six and rebranded as DAY6. The group’s name carries symbolic meaning: the members represent the six days of the week, while fans represent the seventh day – together completing a full week.

DAY6 officially debuted on September 7, 2015, with the EP The Day, led by the single “Congratulations.” The album reached No. 2 on Billboard’s World Albums Chart within a week of release, an early signal of the group’s international potential. In February 2016, member Junhyeok departed from the group and the label, leaving DAY6 to promote as a five-piece.

2017 became a defining year with the “Every DAY6” project – a monthly release campaign in which the band dropped two new songs every month for a full year, ultimately producing 25 tracks. Songs from the first half of the project were compiled into their debut full album Sunrise, while the latter half formed Moonrise. This period produced fan-favorite tracks such as “You Were Beautiful” and “I Like You,” cementing DAY6’s identity as a band capable of blending rock intensity with radio-friendly melody.

The group expanded into the Japanese market in 2018 with the single “If -Mata Aetara-,” followed by their Japanese debut album Unlock. Back home, the “Book of Us” EP series (2019–2021) – including Entropy, Gravity, The Demon, and Negentropy – became one of their most acclaimed bodies of work, consistently landing in the Top Three of Korean album charts.

Between 2021 and 2023, DAY6 underwent significant change. Member Jae left the group and JYP Entertainment at the end of 2021, and all four remaining members enlisted for mandatory military service in sequence. The group fully reunited by December 2023, celebrating with a Christmas concert at Korea University’s Hwajeong Tiger Dome. Their comeback EP, Fourever (March 2024), marked a triumphant return to the charts.

2025 marked DAY6’s 10th anniversary, celebrated with the fourth studio album The Decade, a sold-out stadium show at Goyang Stadium (a first for a K-band), and the world tour Forever Young: Finale, which made history as the first K-band concert held at KSPO Dome, drawing 96,000 attendees across six shows. The band also released a road-trip documentary film, 6DAYS, and closed the year with the holiday single “Lovin’ the Christmas.” Their anniversary tour, The DECADE, is continuing into 2026 with stops across Asia.
