Gongchan was born in 1993 on August 14, which makes him 22 years old (23 in Korean age). Though he is approaching his mid-twenties, some may still consider him an 'adult child.' 

Baro uploaded a short clip of the maknae on his Instagram waving happy peace signs, hovering over a delicious-looking cake.

Go wish Gongchan a happy birthday!
