Girl's Day – South Korean k-pop band
The current lineup of Girl’s Day includes Sojin, Minah, Yura, and Hyeri. Initially, there were other members in the group. However, two of them, Jisun and Jiin, left two months after the debut to pursue other goals. To replace them, the label invited Yura and Hyeri. The third member of the initial lineup, Jihae, left the band for personal reasons in 2012.
The initiative and the funding for the band’s creation belongs to Dream Tea Entertainment. Its managers arranged the recording of the first single "Tilt My Head" in July 2010. Two days later, the musicians presented a debut EP, which they called Girl's Day Party #1. The album reached the 12th spot of South Korea Gaon Albums Chart. Later that month, the group presented two music videos for the singles "Tilt My Head" and “How About Me". Both videos collected thousands of views on YouTube. The fans started trying to book Girl’s Day for private events.
In 2011, the group released a new EP, Everyday. It climbed to a higher position than the previous one, settling on the 4th spot of South Korea Gaon Albums Chart. The single “Twinkle Twinkle" became the South Korean hit of the year. It was included in the digital album, Girl's Day Party #3. The same year, the band gave its first abroad concert in Taiwan. It was arranged by Korea Tourism Organization. Other popular South Korean groups were also invited.
