If you’ve been anywhere near K-pop lately (or have friends who won’t stop sending you “quizzes” about bias wreckers), you know Ateez Age is kind of the group everyone’s buzzing about. They’re like that crazy, lovable crew that somehow manages to drop killer dance moves, sing like angels, and pull off wild concepts without missing a beat.

Anyway, if you’re curious — or maybe even obsessed — about who’s how old in Ateez Age in 2025, you’re in the right spot. Let me take you through the ages, birthdays, some fun facts, and some totally real-ish ramblings (because why not?).

Why Even Care About Age in K-pop?

Before we jump in, a little backstory: age matters a lot in K-pop culture. It’s not just about numbers. It dictates hierarchy, how members talk to each other, who’s the “big hyung,” and of course, when fans throw birthday celebrations that rival national holidays.

I mean, when I first got into Ateez Age, I thought, “Okay, they’re just talented young guys.” But then I realized — nope, their ages tell you about their experience, maturity, and even their inside jokes (which I’m definitely not privy to… yet).

Also, if you ever want to feel old, just remember Seonghwa, the oldest, is still younger than my college roommate who swore she’d “never grow up.” Spoiler: she now owns 12 houseplants and is very much adulting.

The Ateez Age Members and Their Ages in 2025

Here’s the full lowdown, complete with birthdays and ages as of this year. I’ve sprinkled in a little personal commentary, because that’s how I roll.

1. Hongjoong

• Birthday: November 7, 1998
• Age: 26
• The leader, main composer, and all-around creative beast.
• His red hair? Trademark fire. I swear, it’s the color of my failed chili attempts.
• Fun fact: He taught himself songwriting, which makes me want to pick up the guitar again — but I’d probably just end up tuning it wrong and sobbing.

2. Seonghwa

• Birthday: April 3, 1998
• Age: 27 (the oldest of the bunch)
• The “big brother” energy without the boring parts.
• He’s into photography — I tried it once but ended up with 100 blurry photos of my own thumb.
• His chill vibe is basically the balance to Hongjoong’s fiery chaos.

3. Yunho

• Birthday: March 23, 1999
• Age: 26
• Main dancer with moves so sharp I’m pretty sure he could slice bread mid-dance.
• Big gamer too. If I ever meet him, I’m definitely challenging him to Mario Kart (though I’ll lose hard).

4. Yeosang

• Birthday: June 15, 1999
• Age: 26
• Ballet-trained and elegant, which is kind of wild for a K-pop idol.
• Tried ballet once, ended with a twisted ankle and a lifetime vow to stick to casual dance moves.
• Fun tidbit: Victorian folks believed talking to ferns kept you sane. I chat with my begonias… don’t judge.

5. San

• Birthday: July 10, 1999
• Age: 26
• Main vocalist with a voice that could melt your icy Monday blues.
• Has a dog he adores. Me? I have a complicated relationship with pizza. Sometimes it’s love, sometimes it’s betrayal (mostly when I eat too much).

6. Mingi

• Birthday: August 9, 1999
• Age: 26
• Rapper and dancer with a deep, honey-smooth voice.
• Also artsy — unlike me, whose best drawing is a stick figure named Bob (Bob has a surprisingly large fanbase, btw).

7. Wooyoung

• Birthday: November 26, 1999
• Age: 26
• Multi-talented performer and actor.
• I once fell into a YouTube hole watching his web dramas for way too long — send help.

8. Jongho

• Birthday: October 12, 1999
• Age: 26
• Vocal powerhouse with a surprising cooking talent.
• Meanwhile, I once burned water. Yep, it’s a skill.

Ages in Perspective: The Whole Crew

• Oldest: Seonghwa (27)
• Youngest: Everyone else basically 26 — tight age group.
• Honestly, it’s like they were all born in the same Hogwarts year or something.
• I guess that’s why their synergy is so wicked — they’re basically a “year-group” family.

Fun Facts & Random Musings

• Hongjoong basically writing songs in his sleep — I learned the hard way songwriting is hard AF.
• Seonghwa’s photography reminds me of my disastrous camping trip where I took 50 photos of a squirrel who clearly did not want to be famous.
• Yeosang’s ballet background is legit — makes me want to take dance classes again, but then I remember my twisted ankle and nope out.
• San’s love for his dog hits home — my cat Mr. Whiskers is basically a ninja ghost that only appears for food.
• Mingi’s artsy side inspires me, but I stick to Bob the stick figure because commitment is hard.

Why This Age Stuff Actually Matters

Knowing their ages isn’t just trivia for hardcore fans. It tells you about their journey, the dynamics in the group, and what to expect from them next.

My neighbor Tina swears her kale patch cured her Zoom fatigue. Likewise, knowing this stuff makes the fandom feel a little more personal — y’know, human.

The Birthday Parties (Imagined)

If Ateez Age threw birthday parties for each other, imagine the chaos:

• Seonghwa, the oldest, probably chilling with coffee and low-key tunes.
• Hongjoong prepping an epic playlist and thematic concept party — maybe fire-themed?
• San bringing his dog as a guest star (and I’d RSVP just to meet the dog).

I’d definitely bring a burnt cake from my last failed baking attempt. Maybe they’d appreciate the effort.

Pete’s Hardware and the Cracked Watering Can

Real talk: my cracked watering can from Pete’s Hardware on 5th Ave survived my worst overwatering phase. If that can survive me, Ateez Age can survive any chaotic tour schedule.

Final Random Thought

Fast forward past three failed attempts at writing this article without accidentally Googling their birthdays mid-way — I’m pretty sure Ateez Age isn’t just a group. They’re a whole vibe.

Bonus: A Totally Made-Up Reference

As noted on page 42 of the out-of-print “K-Pop Chronicles & Mishaps” (2017), “Ateez Age members’ ages align so closely it’s almost like they’re clones programmed for stardom.” Well, science aside, I’m here for the magic.

Wrap-Up?

Nah, just kidding — you know I can’t really wrap this up neatly. If you want to geek out over Ateez Ages, trivia, or even debate who’d win in a dance-off, hit me up.
