If you’re a fan of K-pop, certain dates just live rent-free in your head. For anyone following Stray Kids, September 22 is basically a global event. That is the official answer to the question: When is Seungmin birthday?
Kim Seung-min was born on September 22, 2000. It’s a day that turns social media into a sea of puppy emojis and blue-themed fan art. Honestly, if you’re not prepared for the sheer volume of "Happy Seungmin Day" posts, your timeline is going to be a wild ride. He’s the group’s "Dandy Boy," their main vocalist, and a guy who somehow manages to be the most savage and most adorable person in the room at the exact same time.

Why September 22 Matters to STAYs
It’s not just about a calendar date. For the fandom (STAY), this day represents the birth of the "Golden Voice" of Stray Kids. Born in Seoul, South Korea, Seungmin didn’t always plan on being an idol. He actually wanted to be a baseball player. Can you imagine? Instead of hitting high notes in "Lose My Breath" or "As we are," he could have been pitching for the KBO.
Luckily for us, he joined JYP Entertainment after winning second place at their 13th Open Audition. He’s a Virgo, which makes total sense if you’ve ever seen how neat and organized he is. Virgos are known for being perfectionists, and Seungmin lives up to that reputation every time he steps into a recording booth.
The Evolution of the "Puppy" Vocalist
When the group debuted in 2018, Seungmin was already a standout, but watching his growth over the last several years has been insane. By 2025 and now into 2026, he has cemented himself as one of the most stable live vocalists in the industry.

- Vocal Technique: He doesn't just sing; he emotes. His performance of "ULTRA" during the 2025 fanmeetings became a viral sensation for a reason.
- The "Savage" Persona: Don't let the "PuppyM" nickname fool you. He is famously witty and isn't afraid to tease his older members, especially Bang Chan or Lee Know.
- Consistency: Whether it's a stadium show in London or a random livestream, his voice sounds exactly like the CD.
How the World Celebrates Seungmin's Birthday
If you happen to be in Seoul around late September, you can’t miss it. The "Seungmin in the City" vibes are real. Cafes across Gangnam and Hongdae get decked out in custom sleeves, photos, and banners. It's kinda like a scavenger hunt for fans. You go from one spot to another, collect stickers, and drink "Seungmin-themed" lattes (usually something sweet but classic).
But it’s not all just coffee and photos. The fandom is huge on charity. For his 25th birthday in 2025, fanbases organized massive donations to animal shelters and children’s hospitals. It fits his vibe perfectly—clean, helpful, and genuinely kind.
Surprising Facts You Might Not Know
- The Helicopter Incident: This sounds like a movie plot, but when he was a kid, a helicopter actually crashed into his apartment building in Gangnam. The wilder part? He still went to school that day. Talk about dedication.
- LA Living: He lived in Los Angeles for about three months when he was in 4th grade. That’s why his English is so good, despite such a short stay.
- Day6 Superfan: If you want to get on his good side, play Day6. He’s the ultimate "My Day" (Day6 fan) and has done some of the best covers of their songs, like "You Were Beautiful."
What to Expect for Future Birthdays
As Stray Kids moves further into their "KARMA" era following their massive 2025 success, the celebrations are only getting bigger. In 2026, we’re seeing even more digital-heavy events, with fans organizing virtual "streaming parties" that bridge the gap between people in the US, Europe, and Asia.
Seungmin birthday traditions usually include:

- The Birthday Live: He almost always goes live to talk to fans, eat a cake (that the members probably tried to mess with), and show off his gifts.
- Official Content: JYP usually drops never-before-seen photos or special "SKZ-RECORD" vocal covers.
- Hashtag Takeovers: Expect #HappySeungminDay and #GoldenVoiceSeungmin to trend worldwide for at least 24 hours.
Honestly, even if you’re a casual listener, it’s hard not to appreciate his journey. He went from a kid who just loved baseball to a man who sells out stadiums and wins "Grand Record" trophies at the KGMA.
If you're planning to join the festivities this year, start looking into local cup sleeve events at least two weeks before September 22. Most organizers announce their locations on X (formerly Twitter) or Instagram using the member's name and the current year. It’s the best way to meet other fans and grab some limited-edition merch that you definitely won't find anywhere else.
Make sure to mark your calendar now. Missing Seungmin birthday is basically a rookie mistake in the STAY world. You’ve been warned!
Next Steps for STAYs: Keep an eye on the official Stray Kids social media accounts around mid-September for the schedule of his birthday livestream. If you're feeling creative, you can start preparing your own fan art or video edits now—the community starts sharing their "birthday countdown" projects as early as September 1st.
