Girl's Day

2010–2011: Debut, lineup change, and Everyday

In July 2010, Girl's Day debuted with five members: Jihae, Jisun, Jiin, Sojin, and Minah. The first song by Girl's Day, "Tilt My Head" ("갸우뚱"), was released July 7. Their debut EP Girl's Day Party #1 was released two days after this release. The group followed up promotions for "Tilt My Head" with the song "How About Me" ("나어때"), for which they released a music video on July 21. Two months after the group debuted, members Jisun and Jiin left the group to pursue individual interests. Current members Yura and Hyeri were then added to the group to replace them. The new lineup's digital release Girl's Day Party #2 became available on October 29. The song "Nothing Lasts Forever" ("잘해줘봐야") was used as the lead track of the digital single.

In March 2011, Girl's Day digitally released Girl's Day Party #3, with the single "Twinkle Twinkle" ("반짝반짝"). On May 7 the group performed in their first overseas concert, which was held in Taiwan. The concert was organized by the Korea Tourism Organization, and also featured performances by U-KISS and Super Junior M. In July, Girl's Day released a second EP titled Everyday, with "Hug Me Once" ("한번만 안아줘") as the title track. The group released Girls' Day Party #4 in September, with the track "Don't Flirt" ("너, 한눈 팔지마!"). The song was written and produced by Gang Jeon-hyong and Nam Ki-san, who also produced previous singles "Twinkle Twinkle" and "Hug Me Once".

2012-2013: Everyday 2, Expectation, and rise in popularity

Girl's Day's third EP, Everyday 2, was released on April 17, 2012. It contained the song "Telepathy", which was written and produced by Sojin, in addition to the title track "Oh! My God". On October 17, Dream Tea Entertainment revealed that Jihae had left the group for personal reasons. The remaining four members returned with the song "Don't Forget Me" ("나를 잊지마요") from Girl's Day Party #5.

In February 2013, Girl's Day released the single "White Day", followed by their first full-length album Expectation on March 14. The album's title track, "Expectation" ("기대해"), became a commercial success and was awarded the 'Long-Run Song of the Year' award at the third Gaon Chart K-Pop Awards. This marked the start of a rise in popularity for Girl's Day. They also promoted the track "Female President" ("여자대통령"), which was named one of the "20 Best K-pop Songs of 2013" by Billboard. Following Expectation, the group released Girl's Day Party #6 with "Please Tell Me" as the title track. They released "Let's Go" ("렛츠 고"), a motivational song written and composed by Sojin.

2014-2016: I Miss You, second album, Japanese debut

On January 3, 2014, Girl's Day released their fourth EP, Everyday 3, which was largely produced by Duble Sidekick. The music video for the title track "Something" ("썸씽") reached over a million views within a day. It became their highest-charting single, peaking at #2 on both Billboard's Korea K-Pop Hot 100 and the Gaon Digital Chart. The song also ranked first on the monthly Gaon Digital Chart, and remained in the top 10 of the Korea K-Pop Hot 100 for eight weeks. Girl's Day live promotions for "Something" won five music show awards, and later won 'Best Dance Performance by a Female Group' at the 2014 Mnet Asian Music Awards. In July, the group released their fifth EP, Everyday 4, with the lead single "Darling". On October 15, the group released the EP and ballad single "I Miss You" ("보고싶어").

In May 2015, Girl's Day released the single "Hello Bubble" in endorsement with haircare brand Mise-en-scène. The group traveled to Okinawa in June to film for the MBC reality programme One Fine Day. Girl's Day released their second full-length album Love, along with its title track "Ring My Bell", in July 2015. During promotions for the album, the group faced controversy over their July 7 appearance on a Korean internet-streamed program, ChoiKoon TV. The Girl's Day members were criticized by audiences for what was seen as disrespectful behavior, and appeared on the stream the following day to offer an apology. On September 30, Girl's Day made their Japanese debut with the album Girl's Day 2015 Autumn Party. It contained Japanese versions of the singles "Darling", "Twinkle Twinkle" and "Ring My Bell". The group also held a showcase in Taipei on November 1, performing twelve of their songs to an audience of 2,000 fans.

Girl's Day ranked 13th in Korea Power Celebrity in 2015. In 2016, the group ranked 26th, whereas member Hyeri ranked 3rd.

2017-present: Upcoming comeback

On March 2, 2017, Dream T Entertainment announced that Girl's Day was set to comeback after a year and a half long hiatus. The agency revealed that the group is in the process of wrapping up recording for their title track, and the comeback was set for late March 2017. On March 10, Dream T Entertainment confirmed that the Girl's Day was set to make their comeback on March 27 with their new mini album.

Ambassadorship for Plan Korea

In August 2013, Girl's Day were appointed honorary ambassadors for the Plan Korea campaign "Because I Am a Girl". That month the group visited Chiang Rai, Thailand, where they carried out volunteer work. The group returned to Thailand a year later to participate in a campaign for girls' birth registration. The entire proceeds from the group's concert in 2014 were donated to support the birth registration of girls in developing countries. In February 2016, Sojin and Yura represented Girl's Day as Plan Korea ambassadors in Cambodia, volunteering at a school where they held art and music workshops. Minah and Hyeri did not join the trip due to illness and drama commitments respectively. In 2017, Hyeri was appointed as one of the ambassadors for the Count Every Child birth registration campaign.
