It was such an exciting and ambitious concept when Blockberry Creative began introducing the members of Loona (or 이달의 소녀 in Korean, meaning “Girl of the Month”) back in September 2016, beginning with Heejin. True to the Korean name, the idea was, over time, to introduce a new member of the group for each month of the year, resulting in a 12-member girl group. Following a long period of individual debut activities for each member, Loona finally officially debuted on August 19, 2018, with the mini-album [+ +] and the lead single “Hi High” releasing a day later. Loona would go on to earn tremendous love from their fandom, Orbit, but in the following years, gross company mismanagement would result in the members suing to break their exclusive contracts. Now, Loona is basically defunct, at least for the moment, but the group lives on in other ways, such as with Odd Eye Circle and Loossemble! So to learn how old all 12 Loona members are, here is the current age and birthday for Vivi, Yves, JinSoul, Haseul, Kim Lip, Chuu, Heejin, Hyunjin, Gowon, Choerry, Olivia Hye (Hyeju), and Yeojin.

How Old Explained: Age and Birthday for All Loona Members

• Vivi is 27 years old and was born on December 9, 1996.
• Yves is 27 years old and was born on May 24, 1997.
• JinSoul is 27 years old and was born on June 13, 1997.
• Haseul is 26 years old and was born on August 18, 1997.
• Kim Lip is 25 years old and was born on February 10, 1999.
• Chuu is 24 years old and was born on October 20, 1999.
• Heejin is 23 years old and was born on October 19, 2000.
• Hyunjin is 23 years old and was born on November 15, 2000.
• Gowon is 23 years old and was born on November 19, 2000.
• Choerry is 23 years old and was born on June 4, 2001.
• Olivia Hye (Hyeju) is 22 years old and was born on November 13, 2001.
• Yeojin is 21 years old and was born on November 11, 2002.

Meanwhile, when Loona debuted as a full group back in August 2020, the members were the following ages: Vivi was 21, Yves was 21, JinSoul was 21, Haseul was a brand new 21, Kim Lip was 19, Chuu was 18, Heejin was 17, Hyunjin was 17, Gowon was 17, Choerry was 17, Olivia Hye was 16, and Yeojin was 15.

Vivi was always the oldest member, while Haseul was generally viewed as the overall leader of Loona — albeit with some ambiguity. Yeojin was always the maknae (the “youngest member”), and when she released her self-titled solo album on January 16, 2017, she was only 14 years old. Along those lines, here is the age that each Loona member was at the individual time each girl debuted with an album release (which all occurred on different dates): Vivi was 20, Yves was 20, JinSoul was newly 20, Haseul was 19, Kim Lip was 18, Chuu was 18, Heejin was narrowly still 15, Hyunjin was just barely 16, Gowon was 17, Choerry was 16, Olivia Hye was 16, and Yeojin was 14.

That is a lot of numbers! Use this birth date image to help you better understand who all of the Loona members are and how old they are:

With current age, birthday, and the complex answers to their ages at debut, that is everything there is to know about how old Loona members Vivi, Yves, JinSoul, Haseul, Kim Lip, Chuu, Heejin, Hyunjin, Gowon, Choerry, Olivia Hye (Hyeju), and Yeojin are!

While the group has gone away for now, many members carry on together at other companies. Modhaus contains JinSoul, Kim Lip, and Choerry as a renewed Odd Eye Circle, as well as Heejin and Haseul as soloists. Meanwhile, Vivi, Hyunjin, Gowon, Olivia Hye, and Yeojin found a redebut as Loossemble at CTDENM. And Chuu is soldiering on as a soloist, as is Yves.
