Every time that a K-pop group from a small company finds success, it is cause for celebration. Such is the case for girl group StayC at High Up Ent., founded by music producing duo Black Eyed Pilseung. Granted, High Up Ent. was purchased by Kakao Entertainment in 2021, so it’s not exactly accurate to classify the company as small anymore — but that too is a testament to StayC’s success! StayC debuted on November 12, 2020 with the single album Star to a Young Culture and the song “So Bad,” and with a combination of talent, hard work, and breathtaking visuals, they have been winning hearts ever since. But if you want to know how old the StayC members are right now, then here is the age and birthday for Sumin, Sieun, Isa, Seeun, Yoon, and J.
StayC Member Birthdays and Age: Explaining How Old Sumin, Sieun, Isa, Seeun, Yoon, and J Are
- Sumin is 22 years old and was born on March 13, 2001.
- Sieun is 22 years old and was born on August 1, 2001.
- Isa is 21 years old and was born on January 23, 2002.
- Seeun is 20 years old and was born on June 14, 2003.
- Yoon is 19 years old and was born on April 14, 2004.
- J is 18 years old and was born on December 9, 2004.
So, at the time that they debuted back in November 2020, simple math tells us that the members’ ages were as follows: Sumin was 19, Sieun was 19, Isa was 18, Seeun was 17, Yoon was 16, and J was 15. J is the maknae, meaning she is the youngest member in the group, but she is known for her distinctive lower-range vocals. Meanwhile, Sumin is the oldest member of StayC, and she was the leader of the group at least until the beginning of April 2023; the group apparently transitioned to rotating the leadership role among members at this point.
StayC are known for their particularly strong and distinctive visuals. However, their songs and videos tend toward lighter and warmer fare, perhaps in the vein of GFriend, as opposed to something a bit edgier as seen with Aespa or Blackpink. In any case, you can use the graphic below to help you pair a name with a face and more quickly absorb how old the StayC members are:
