How Old Were the BTS Members When They Debuted?

They’re one of the biggest boy bands in the world, releasing chart-topping songs like “Dynamite,” “Life Goes On,” and “Butter.” However, these artists have been working for several years, some of them even appearing with the K-pop group as teenagers.

BTS debuted as a group in 2013

These idols each began training at different times, officially joining the group at different points, as well. First was RM, then Jungkook, then J-Hope. As a group of seven, this boy band debuted on June 13, 2013, marking the date “BTS Day” for fans across the globe.

Ages in Korea are somewhat different from how ages are counted internationally. According to Showbiz Cheat Sheet, in Korea, when you are born, you are considered to be one year old whereas internationally you wouldn’t be one year old until your first birthday. 

“They also don’t add a year to their age on their actual birthday,” the article continues. “Instead, everyone adds a year to their age on the same day, which is January 1.” If you were to live in Korea, depending on what time of the year it was, you could be considered one to two years older than your “international age.”

Because fans know the birth dates of the BTS members, they also know their international age at the time of their debut. The oldest member of the group, Jin, was 21 years old (international age) at the time of his debut.
