If you are asking how old is Yeonjun from TXT, the direct answer is that Yeonjun is 26 years old as of August 11, 2026. He was born on September 13, 1999, so he will celebrate his 27th birthday on September 13, 2026. His age is sometimes shown differently on fan pages because older Korean age-counting customs do not match the international system now used for most official purposes.
Yeonjun is the oldest member of TOMORROW X TOGETHER, commonly shortened to TXT. His stage presence, dance ability, fashion influence, and long career as a performer have made his birthday and age popular search topics among new MOA and longtime fans alike. This guide explains the calculation, clears up Korean-age confusion, and places his age within the timeline of TXT’s career.
How Old Is Yeonjun From TXT Right Now?
Yeonjun is 26 under the international age system on August 11, 2026. The calculation is straightforward: subtract his birth year, 1999, from the current year, 2026, to get 27, and then subtract one because his September birthday has not occurred yet in 2026.
The answer changes on his birthday rather than on January 1. From September 13, 2025, through September 12, 2026, Yeonjun is 26. Beginning on September 13, 2026, he is 27 and remains that age until September 12, 2027.
Quick answer: Yeonjun is 26 years old as of August 11, 2026. His date of birth is September 13, 1999, and his next birthday will make him 27.
What Is Yeonjun’s Birthday?
Yeonjun’s birthday is September 13, 1999. His official Weverse community profile identifies him as a member of the five-person group TOMORROW X TOGETHER and gives this birth date, making it a reliable source for age calculations.
Because September 13 falls late in the calendar year, a quick year-only calculation can overstate his age before his birthday. For example, 2026 minus 1999 equals 27, but Yeonjun does not actually turn 27 until September 13. Always check whether the birthday has occurred in the year you are calculating.
Yeonjun’s Zodiac Sign
A September 13 birthday places Yeonjun under the Western zodiac sign Virgo. Virgo dates are generally listed from late August to late September, although astrology is a cultural interest rather than a scientific way to describe personality.
Fans often connect Virgo traits such as attention to detail, discipline, and a strong work ethic with Yeonjun’s performance style. Those interpretations are subjective, but the zodiac question appears frequently alongside searches about his birthday and age.
How to Calculate Yeonjun’s Age in Any Year
You can calculate Yeonjun’s international age for any date with a simple two-step method. Start with the target year minus 1999, then check whether September 13 has already passed in that target year.
- Subtract 1999 from the year you want to check.
- If the date is before September 13, subtract one more year.
- If the date is September 13 or later, keep the original result.
For example, on January 1, 2030, the initial subtraction gives 31. Because January 1 comes before September 13, his age on that date will be 30. On September 13, 2030, he will turn 31.
This birthday-based method is the standard international system used in most countries. It is also the clearest system for evergreen articles because the calculation can be updated precisely instead of relying on a label that may mean different things in different cultures.
Why Do Some Websites Show a Different Age for Yeonjun?
Different answers usually come from one of three issues: the article is old, the page has not been updated after a birthday, or the writer is using a Korean age convention. Search snippets may also retain an outdated number even after the page itself changes.
Another common error occurs when a writer subtracts 1999 from the current year but forgets to check whether September 13 has passed. Before his birthday in 2026, that shortcut produces 27 even though the correct international age is 26.
International Age Versus Traditional Korean Age
Under the international system, a baby is zero at birth and gains one year on each birthday. Under the traditional Korean counting method, a person was considered one at birth and everyone added a year on January 1. That system could make a person’s Korean age one or two years higher than their international age, depending on the date.
South Korea standardized the use of international age in most legal and administrative contexts in 2023. However, older interviews, archived fan profiles, translated posts, and casual conversations may still refer to the traditional system. For clarity, current profiles should state the date, the age system, and the date on which the age was checked.
Is Yeonjun 26, 27, or 28 in 2026?
All three numbers can appear online, but they do not mean the same thing. Yeonjun is 26 internationally before September 13, 2026, and 27 internationally on and after that date. A traditional Korean-age calculation may label him 28 during 2026 because it begins at one and adds a year on January 1.
For ordinary questions such as “how old is Yeonjun from TXT,” the international age is the most useful answer. Therefore, the correct answer on August 11, 2026, is 26.
How Old Was Yeonjun When TXT Debuted?
TOMORROW X TOGETHER officially debuted on March 4, 2019. Since Yeonjun’s 20th birthday had not yet occurred, he was 19 years old internationally on the debut date. He turned 20 later that year on September 13.
This detail helps put his career into perspective. By August 2026, Yeonjun has spent more than seven years as a debuted TXT member, in addition to his pre-debut training. Fans who first saw him during The Dream Chapter: STAR era have watched him progress from a 19-year-old rookie to an established 26-year-old performer.
Yeonjun’s Age During Key Career Years
An age timeline makes it easier to connect major stages of his career with his life at the time. The age below uses the international system and refers to his age on the listed date or during the described period.
- September 13, 1999: Yeonjun was born.
- March 4, 2019: He debuted with TXT at age 19.
- September 13, 2019: He celebrated his 20th birthday.
- September 19, 2024: He was 25 when his solo track “GGUM” was released.
- September 13, 2025: He turned 26.
- August 11, 2026: He is still 26.
- September 13, 2026: He will turn 27.
The timeline also shows why an article should include a fact-check date. A number that is accurate in August may become inaccurate in September even when every other biographical detail remains correct.
Is Yeonjun the Oldest Member of TXT?
Yes, Yeonjun is the oldest member of TOMORROW X TOGETHER. The group has five members: Yeonjun, Soobin, Beomgyu, Taehyun, and Hueningkai. Being the oldest does not automatically mean being the leader, however; Soobin holds the group’s leader role.
New fans sometimes assume the oldest member must be the leader because that arrangement exists in some groups. TXT is a useful reminder that age order and official roles are separate. Yeonjun is the eldest member, while Soobin is the leader.
TXT Members in Age Order
The official Weverse community information lists the members’ birth dates. From oldest to youngest, the order is Yeonjun, Soobin, Beomgyu, Taehyun, and Hueningkai.
- Yeonjun: September 13, 1999
- Soobin: December 5, 2000
- Beomgyu: March 13, 2001
- Taehyun: February 5, 2002
- Hueningkai: August 14, 2002
Age order can help new MOA recognize references such as “oldest member” or “maknae,” but it does not define the members’ personalities, skills, or importance. Each member contributes a distinct vocal, performance, and group dynamic.
Who Is Yeonjun?
Choi Yeonjun, professionally known as Yeonjun, is a South Korean singer, dancer, rapper, songwriter, and performer. He debuted as a member of TXT under Big Hit Music in 2019 and became known for his versatility across choreography, vocals, rap, fashion, and stage performance.
He was the first TXT member publicly introduced before the group’s debut. That early introduction created significant interest around both Yeonjun and the then-new group. Over time, he developed a reputation as an all-round performer and participated in group releases, collaborations, hosting work, fashion activities, and solo music.
What Does TXT Stand For?
TXT stands for TOMORROW X TOGETHER. The group name is commonly pronounced “Tomorrow by Together,” and the X is read as “by” in the official name. Fans of the group are known as MOA.
The group debuted with five members and has built a catalog that frequently explores youth, growth, friendship, change, temptation, and the transition into adulthood. Yeonjun’s age at different releases can be interesting to fans because those themes often evolve alongside the members themselves.
Why Yeonjun’s Age Is a Popular Search
K-pop audiences constantly welcome new listeners, and age is one of the fastest ways to understand a group’s member order and career timeline. A viewer may discover Yeonjun through a recent performance, a fashion event, a solo release, or a TXT music video and then want basic profile information.
The question also remains popular because age information becomes outdated every year. Pages that show a fixed age without a verification date can conflict with newer results, encouraging fans to search again. Korean and international age conventions add another layer of confusion.
For publishers, the best answer is not simply a number. A useful page includes the full date of birth, the current age, the date on which it was verified, the next birthday, and a brief explanation of the age system being used.
How to Keep an Age Article Accurate
Celebrity age pages can rank well in search but require careful updates. A strong article should avoid copying an age from another summary and should calculate it directly from a reliable birth date.
- Cite an official artist or community profile for the birth date.
- Add a visible “last fact-checked” date.
- State whether the age uses the international system.
- Mention the next birthday so readers can understand when the number changes.
- Review the article each year shortly before and after September 13.
This approach also improves answer-engine clarity. Search engines and AI assistants can extract the direct answer more reliably when the date, age, and qualification appear together in a concise sentence near the top.
