BTS is a group composed of seven members, each with their own individual age. Therefore, there isn't a single "BTS Korean age" but rather individual Korean ages for each member at any given time.
According to the provided reference, which discusses BTS's new Korean age system change, specific Korean ages were mentioned for some members:
- RM (Namjoon): The leader's Korean age is stated as 28 years old.
- Suga: Suga's Korean age is stated as 30 years old.
The reference also mentions members Jin and J-Hope, but their specific numeric Korean ages are not clearly provided in the excerpt. Other members, such as V, Jimin, and Jungkook, are not mentioned in the provided text regarding their ages.
These ages likely refer to the traditional Korean age system which counts a person as one year old at birth and adds a year on each New Year's Day (January 1st), although South Korea officially adopted the international age system for most purposes starting in June 2023.
