When did BTS start? A verified timeline of the group’s formation and debut

What counts as BTS’s start date

BTS’s "start" can be described in two ways: when the group originally formed at Big Hit Entertainment and when they officially debuted with music. Formation began in early 2011 with the first members joining and training, while the official debut with the single album 2 Cool 4 Skool and the track "No More Dream" occurred on June 13, 2013. Understanding both milestones clarifies common confusion around timelines.

How Big Hit selected and built the original line-up

Before any music released, BTS originated through a careful recruitment and audition process led by Bang Si-hyuk. Trainees practiced for years in singing, choreography, and language, and early member line-up changes reflected the goal of finding the right creative fit. This phase was foundational to what followed in 2013 and beyond.

Formation versus debut: what’s the difference?

Formation refers to when the members came together under Big Hit, began training, and shaped the group’s creative direction, while debut marks the first official music release and public performance. Debut is usually the date used in chart eligibility, careers timelines, and fan commemorations, but formation explains how the group was built.

Pre-debut activities that defined the early era

Before June 2013, BTS appeared on early web content, radio features, and small showcases. These appearances were critical for introducing the band’s message and music style, culminating in their broadcast debut and first televised performance, which validated their preparation.

Notable early milestones (2013–2015)

After debut, a series of releases and appearances established BTS’s presence in Korea and set the stage for future growth. Their first studio album and further music releases created a baseline catalog, while performances expanded their audience beyond early fans.

  • June 13, 2013: Debut album and music video released
  • June 2013: First live broadcast stage on a major music program
  • 2014: First full-length studio album broadens musical reach
  • 2015: Continued touring and content builds momentum

Common questions about BTS’s start

When did training for BTS begin?

Training for the original members started in 2 Bang Hit’s training system, with many recruits joining as early as 2009–2010, but the recognized formation of BTS as a named entity began in 2011 and solidified in 2013 ahead of debut.

Why is June 13, 2013 treated as the official start?

June 13, 2013 marks the first commercial music release and televised performance, which are standard reference points for an artist’s public career. Pre-debut activities were part of preparation, but this date represents the group’s formal introduction.

How does formation differ from debut in K-pop?

Formation covers internal building, member selection, and training, while debut refers to the first publicly released songs and performances. Both matter, but debut is most often cited in mainstream timelines and metrics.
