Whenever June rolls around I get ridiculously sentimental—Sunoo's birthday is one of those days that fills streaming timelines with fan art and cakes. He was born on June 24, 2003, so as of August 30, 2025 he’s 22 years old by international reckoning. If you follow the Korean age system (the one that counts you as one at birth and adds a year every January 1), he’s considered 23 right now. I love how those two age numbers sit together; it’s a small cultural thing but it changes how fans talk about milestones.
As a long-time fan, I always notice little traditions: fans coordinating charity projects, streaming his favorite songs, or making collage videos of his cute live moments. Sunoo’s birthday vibes tend to be soft and wholesome—lots of pastel edits and balloon emoji—so whether you call him 22 or 23, the celebrations feel the same. If you want the absolute official confirmations, the company profile and music show bios list the June 24, 2003 date, and fan communities usually have countdowns pinned for the day.
If you’re planning to wish him happy birthday, a sweet tweet or a small fan drawing goes a long way. I’ll probably rewatch some of his funniest live clips and bake something tiny; it’s my ritual now.
