DAY6 Member Profiles 2026: Ages, Heights, Fun Facts & Everything You Need to Know

DAY6 (데이식스) isn’t your average K-pop group — and if you’ve ever seen them perform live, you already know exactly why. This South Korean rock band under JYP Entertainment plays their own instruments on stage, writes the majority of their own music, and consistently delivers the kind of emotionally raw, hook-heavy pop rock that sticks with you for days. In a genre often defined by carefully choreographed performances, DAY6 stands apart as a genuine K-band in every sense of the word.

Whether you’re a longtime My Day (that’s the official fandom name!) or you’ve just discovered songs like “You Were Beautiful,” “Welcome to the Show,” or “Melt Down,” this guide is your one-stop resource for everything DAY6 in 2026. We’re talking full DAY6 member profiles, birthdays, positions, fun facts, a complete discography, their jaw-dropping list of achievements, and a full breakdown of their world tours — including what’s happening in 2026.

Let’s dive in.

DAY6 made their official debut on September 7, 2015, with the mini album The Day under JYP Entertainment. The name “DAY6” originally came from a six-member lineup, where each member represented one day of the week — and the fans (My Day) represented the seventh day, completing the week together. That fan-focused philosophy has stayed at the heart of everything they do.

DAY6 Member Profiles 2026

Member Overview Table

SUNGJIN — Leader & Main Vocalist

SUNGJIN

Before his debut, Sungjin was actually extremely shy — performing in the spotlight gradually gave him his now-charismatic stage presence.

His dream job if he weren’t in DAY6? A therapist. He genuinely loves listening to people and helping them work through problems.

Jae famously gave Sungjin the nickname “Bob” because he thought he looked like Bob the Builder — so naturally, Sungjin dressed as Bob the Builder for DAY6’s Halloween performance of “Sweet Chaos” on M Countdown.

Young K’s nickname for Sungjin is “Mosquito Head Hunter” because Sungjin is apparently legendary at killing mosquitoes.

He appeared on the Korean TV show Hidden Singer Season 2 and tried to imitate JYP’s (Park Jin-young’s) voice — he made it to the third round before being eliminated.

He feels most proud of himself when he finishes writing a song while in a rough emotional state and it turns out great.

Sungjin can do a spot-on impression of SpongeBob’s laugh and Mr. Krabs.

Despite rarely showing it on broadcasts, Sungjin is actually a very talented dancer — he just prefers to “ugly dance” for fun on camera.

He doesn’t enjoy doing aegyo (cute acts) and reportedly gets annoyed when Wonpil does it.

Sungjin doesn’t particularly like physical skinship (touching/hugging), making him slightly more reserved in that regard compared to some of his members.

YOUNG K — Main Rapper, Main Vocalist & Chief Songwriter

YOUNG K

Young K moved from South Korea to Toronto, Canada, in high school and lived there for roughly four years — which is where his near-perfect English comes from.

His childhood dream wasn’t music at all — it was to become a professional basketball player.

He started his music career in 2010 under the name “Brian Kang” as part of a musical trio in Toronto, Canada.

He was scouted for JYP Entertainment alongside his bandmate Don Lee (from 3rd Degree) after being spotted performing in Toronto.

Young K appeared in both Dream High 1 and Dream High 2 as a backup dancer before his DAY6 debut.

He prefers to be called “Young K” but recalls that almost everyone still called him “Brian” for years.

His group 3rd Degree once won first place in a Math Dance Competition held in Canada.

Young K has writing and/or composition credits on nearly every single DAY6 song — he is widely regarded as one of the most prolific K-pop idol songwriters in the industry.

He hosted his own radio show on MBC Radio, further highlighting his communication skills and intellectual depth.

Young K enlisted in the Korean military in January 2021 and was discharged in August 2022, during which time he reportedly continued writing song drafts.

WONPIL — Lead Vocalist & Keyboardist

WONPIL

Wonpil used to be Sungjin’s roommate back when DAY6 first debuted — they have since moved to individual rooms.

Dowoon once got upset with Wonpil for wanting to share the same bed, which became a well-known funny moment among fans.

Wonpil is beloved in the fandom for his emotional vulnerability — he’s known to get teary-eyed quite easily, especially during heartfelt moments with fans.

His keyboard arrangements are one of DAY6’s sonic signatures — that lush, warm texture underlying many of their mid-tempo and ballad tracks often comes from Wonpil’s layers.

He released the solo album Pilmography while on hiatus from group activities, showcasing his deeply personal songwriting voice.

Wonpil’s INFP personality type shows clearly in his music — his lyrical themes tend to be introspective, nostalgic, and emotionally honest.

Fans describe his smile as one of his most endearing features, often calling it his “trademark bright smile.”

He is known for his gentle and warm personality offstage, often described as one of the sweetest members in casual interactions.

His synthesizer work adds a modern, atmospheric quality to DAY6’s sound — bridging the gap between their rock roots and more contemporary pop textures.

Wonpil has contributed to numerous DAY6 compositions and is recognized as an exceptional melodic songwriter alongside Young K.

DOWOON — Drummer, Vocalist & Maknae

DOWOON

Dowoon has been playing drums since he was sixteen years old — he is entirely self-made as a drummer, having developed his skills through dedicated practice.

He joined DAY6 when the group was still called 5LIVE, and his addition was part of the lineup change that eventually led to the “DAY6” rebrand.

The most members of DAY6 agree that Dowoon is the “cutest” among them — he’s been voted as such multiple times in fan and member discussions.

His ears turn noticeably red when he’s shy or embarrassed — a charming tell that fans have pointed out for years.

Jae used to call Dowoon his “A++ student in English,” helping him practice during group activities.

He has taken vocal lessons and surprised fans over the years by gradually stepping up as a vocalist, proving there is much more to him than just his drumming.

Dowoon made his solo debut in September 2021 with the single “Out of the Blue” before enlisting in mandatory military service.

His drumming style is described as dynamic yet controlled — he gives DAY6’s live performances their rock-solid rhythmic backbone without overshadowing the melodies.

He’s known for bringing playful, lighthearted energy to group content — often the one making other members laugh with unexpected humor.

When asked what kind of girl he likes, Dowoon has consistently said he’s drawn to someone with a pretty smile — which fans find very on-brand for his sincere, warm personality.

That’s not just a milestone for DAY6; it’s a statement for what a live-instrument K-band can achieve.

For any music lover — K-pop fan or not — a DAY6 concert is one of the most exciting live experiences in music today.
