How Old Are the Zerobaseone (ZB1) Members?

The Mnet boy group survival program Boys Planet gave birth to the K-pop group Zerobaseone, managed by WAKEONE. The company boldly declared Zerobaseone will “stand supreme as the center of the 5th generation K-POP,” and the group’s name refers to the group “starting from zero” and being “born as one” to create a “gorgeous beginning” together. That is quite the hype! Zerobaseoneone originally made their debut on July 10, 2023. But to learn how old the Zerobaseone (ZB1) members are right now, here is the current age and birthday for Kim Jiwoong, Zhang Hao, Sung Hanbin, Seok Matthew, Kim Taerae, Ricky, Kim Gyuvin, Park Gunwook, and Han Yujin.

Hanbin is the leader of the group, as announced in a fun video from May 2023. Meanwhile, Yujin is the maknae of ZB1, meaning he is the youngest member of the group. Between Jiwoong and Yujin, there is an age gap of more than eight years, but that’s bound to only increase the number and variety of fans the group is able to garner.
