How old are the KATSEYE members? See every member's birthday and age from oldest to youngest, calculated by international age as of October 7, 2026.
As of October 7, 2026, KATSEYE members range in age from 18 to 24. Manon is the oldest member at 24, and Yoonchae is the youngest at 18. Every age in this post uses international age, the system used in the United States: age starts at zero and increases on each birthday.
These ages are tied to the reference date. Lara turns 21 on November 3, Yoonchae turns 19 on December 6, and Sophia turns 24 on December 31. If you are reading this later, add one year for any member whose birthday has passed.
How the ages were calculated
Each age is the reference year minus the birth year, with one year subtracted when the member's birthday had not yet occurred by October 7. That is why Lara is listed at 20 rather than 21, Yoonchae at 18 rather than 19, and Sophia at 23 rather than 24.
Different pages may show different numbers simply because they were checked on different dates. This guide uses international age only and states the reference date so the calculation can be checked.
KATSEYE members from oldest to youngest
Manon was born on June 26, 2002, making her the oldest member of KATSEYE. She is 24 as of the reference date.
Sophia was born on December 31, 2002, about six months after Manon. Because her birthday falls on the last day of the year, she is 23 until December 31, 2026.
Daniela was born on July 1, 2004. Her birthday had already passed by the reference date, so she is 22.
Lara was born on November 3, 2005, and Megan was born on February 10, 2006. Both are 20 on the reference date, but Lara is older by a little more than three months.
Yoonchae was born on December 6, 2007, making her the youngest member of KATSEYE at 18. She is from Seoul and is the group's South Korean member.
This age order is only a chronological list of birthdays. It does not represent rank, seniority, popularity, or official roles within the group.
What KATSEYE is and where Korea fits in
KATSEYE is a six-member global girl group formed by HYBE and Geffen Records. The group is based in Los Angeles, and its members come from the United States, the Philippines, Switzerland, and South Korea.
The lineup was selected through The Debut: Dream Academy, a global audition project developed by HYBE and Geffen Records. Twenty contestants took part, and the final six members were announced in November 2023.
KATSEYE's connection to Korea comes primarily from HYBE and the K-pop artist-development methodology used to form and train the group. The most accurate description is a U.S.-based global girl group shaped by a K-pop training system, rather than a Korean girl group.
