SEVENTEEN Saju: 13 Members' Charts, Hidden Twins and the Missing Element

Thirteen members means thirteen birth dates, and when you run all of them through a saju engine, SEVENTEEN turns out to be full of hidden twins. Two members share a Day Pillar. Two more share the same Year and Month Pillars. One member has the exact same three pillars as BTS's V, because they were born on the same day. And across all thirteen charts, one of the five elements is in very short supply.

This post reads every SEVENTEEN member through Korean saju, using only what their public birth dates can tell us. If you want to find your own place in the group as you read, a free saju reading gives you your Day Master and Five Elements count in about a minute.

How We Read These Charts

Every pillar, ten god and star below comes from the Sajumuse saju engine, the same engine behind more than 260 paid Sajumuse reports. No member has an official birth time, so we never guess one. We ran each public birth date through the engine and report only what the date fixes on its own: the Year, Month and Day Pillars, their hidden stems, ten gods and the stars that sit on them. Every Day Pillar was also checked against the standard day count formula, and all thirteen match. Anything that depends on the birth hour, such as how strong each Day Master is, we leave out.

The readings are written by our Korean saju counselor, certified in Korea as a Myeongri Psychological Counselor (Level 1) and Family Psychological Counselor (Level 1). This is a chart study built on public information for CARATs and the curious. No member asked us for it, and it makes no predictions about anyone's personal life.

All 13 SEVENTEEN Members at a Glance

"Hidden only" means the element is absent from the six visible characters but sits inside a branch as a hidden stem, a stored trace rather than a true gap.

What the Group Chart Shows

The element SEVENTEEN runs short on: Metal

Count the visible characters across all thirteen charts (78 in total) and you get Wood 22, Earth 20, Water 17, Fire 13 and Metal 6. Metal, the element of edges, rules and finishing, is by far the thinnest. Six members (Joshua, Jun, Hoshi, Wonwoo, Woozi and Dino) have no Metal at all on their three pillars, not even hidden, and only S.Coups and DK have Metal as their Day Master.

In saju, a group short on Metal tends to be warm, generous and creative, and to rely on a few people to draw the lines. Fans may notice that the two Metal Day Masters include the leader. Metal's color in the Korean five color system is white; the fandom's official colors, Rose Quartz and Serenity, happen to sit elsewhere. Our guide to lucky colors by element explains the system.

Four rain Day Masters and three mountains

The most common Day Master in SEVENTEEN is 癸, Yin Water: Hoshi, Woozi, The8 and Seungkwan. 癸 is rain and mist, the element that is perceptive, emotionally quick and hard to pin down. The next most common is 戊, Yang Earth, the mountain: Jeonghan, Jun and Mingyu. A group where four people are rain and three are mountains has a built-in rhythm in saju terms: Earth contains Water, Water softens Earth. Our guide to the ten Heavenly Stems describes each Day Master in full.

The hidden twins

• Woozi and Seungkwan share a Day Pillar, 癸亥. Same Day Master, same Day Branch. Saju reads the Day Pillar as the self, so on that level they are as close as two charts get.
• Jun and Hoshi share a Year and Month Pillar. Born five days apart in June 1996, both have 丙子 for the year and 甲午 for the month. Only the day separates the mountain (Jun, 戊寅) from the rain (Hoshi, 癸未).
• Jun and Mingyu share a Day Pillar, 戊寅. So does Stray Kids' Bang Chan, a fellow 1997 liner of Mingyu's. Our Stray Kids saju post reads his version of it.
• Joshua and BTS's V were born on the same day. Both were born on 30 December 1995, so their three certain pillars are identical: 乙亥, 戊子, 乙未. Our BTS saju colors post reads that exact chart.

Member Deep Cuts

S.Coups: The Leader in a Year of Officers

S.Coups is 辛, Yin Metal, the jewel, on a 未 Day Branch. Fire, the element that polishes Metal, appears only as a hidden stem. 2026 is a 丙午 Fire year, and for a 辛 Day Master that Fire is the Officer: responsibility, title and structure. 丙 and 辛 are also a classic combining pair in saju, a year that tends to bind a person more closely to their role.

Jeonghan: The Mountain With No Fire

Jeonghan is a 戊 Yang Earth Day Master on 辰, and his chart has no Fire at all on the three pillars. For an Earth Day Master, Fire is the resource element: rest, support, learning. Our engine reads 2026 as a resource year at the 제왕 (Emperor) stage, so the element his chart lacks arrives in full force. Our post on missing elements explains why that pattern matters.

Joshua: V's Chart Twin

Joshua's 乙亥 / 戊子 / 乙未 makes him a Yin Wood vine born in deep winter, with no Metal anywhere and Fire only hidden in 未. A winter vine wants sun, which is why Fire reads as his most welcome color. Our engine flags 문곡귀인, a star tied to artistic and literary talent, and 천을귀인, the Heavenly Noble, on his Month Pillar.

Woozi: The Producer With Stored Output

Woozi's chart is Water heavy, four of six characters, with a 癸亥 Day Pillar at the 제왕 stage and a second 亥 in his month. For a 癸 Day Master, Wood is output: creation, composition, what you make. His chart shows no visible Wood, but both of his 亥 branches hide a 甲, the Hurting Officer, the star of original, rule bending creative work. Output stored twice under the surface is a fitting pattern for the member who writes and produces so much of the group's music.

Seungkwan: A January Baby Who Is Still an Ox

Seungkwan was born on 16 January 1998, before 立春 (Ipchun) on 4 February. In saju the year turns at Ipchun, not on January 1 or Lunar New Year, so his saju year is 丁丑, the Ox, not the Tiger. Our explainer on why the saju year changes at Ipchun covers this. His Year and Month Pillars both sit on 丑, and he shares his 癸亥 Day Pillar with Woozi.

DK: All Five Elements

DK is the only member whose three pillars hold all five elements. His Day Master is 辛, Yin Metal, on 卯 Wood, born in a 壬寅 month at the start of spring. Our engine marks 천을귀인 on his month and the General Star on his Day Pillar, a star of stamina under pressure. Fans know he shares his birthday with Vernon; their charts are a year apart and very different.

Vernon: Three Traveling Horses

Vernon is 丙, Yang Fire, the sun, on a 申 Day Branch, born in a 寅 month of a 寅 year. Two Tigers give him heavy Wood, his resource element, and our engine marks 역마, the traveling horse star, on all three of his pillars: movement, travel, living across places. Water appears only as a hidden stem. In 2026 the Fire Horse year arrives as his own element at the 제왕 stage, with the General Star active by year.

Dino: Two True Gaps and Pure Output

Dino's 甲午 Day Pillar sits on Fire, and his month is 丙寅. For a 甲 Yang Wood Day Master, Fire is output, so his chart is built around performance and creation, a fitting shape for a main dancer who choreographs. He is also the only member missing two elements outright: no Metal and no Water on his three pillars, even hidden.

The rest of the line

Jun (戊寅) and Mingyu (戊寅) are mountain twins on the same Tiger branch, read by the engine at the Birth stage with Officer energy underneath: responsibility that grows with them. Hoshi (癸未) is rain on summer Earth, the Officer under the self, and his year carries the General Star from its branch. Wonwoo (乙卯) is the most Wood heavy member, a vine on its own root at the 건록 stage, strong and self-directed. The8 (癸丑) is the only member with no Wood at all; the engine flags 괴강 on his 庚戌 Month Pillar, a mark of discipline and a strong will.

The Units in Saju Terms

BSS (Seungkwan, DK, Hoshi). Two Yin Water Day Masters and one Yin Metal. Metal generates Water, so in saju DK is the resource for both of them, the one who feeds the energy the other two run on.

Performance Team (Hoshi, Jun, The8, Dino). Two rain, one mountain and one tall tree. Earth holds Water, Water feeds Wood: a chain rather than a clash.

Hip-Hop Team (S.Coups, Wonwoo, Mingyu, Vernon). Metal, Wood, Earth and Fire: four different Day Master elements and no Water Day Master among them, a team of contrasts.

2026 and 2027 for SEVENTEEN

These are tendencies for each Day Master type, not predictions about events. In 2026, a 丙午 Fire year, the three Earth members (Jeonghan, Jun, Mingyu) are in a resource year, the four Water members (Hoshi, Woozi, The8, Seungkwan) in a wealth year, and the Wood members (Joshua, Wonwoo, Dino) in an output year. In 2027, a 丁未 Fire Goat year, the heat continues more gently. For a group short on Metal and running warm, the useful advice in saju terms is the same for all thirteen: protect rest and keep clear routines.

Frequently Asked Questions

Which SEVENTEEN member has the same saju as BTS V?

Joshua. He and V were both born on 30 December 1995, so their Year, Month and Day Pillars are identical (乙亥, 戊子, 乙未). Only their unknown birth hours could separate the charts.

What is the most common Day Master in SEVENTEEN?

癸, Yin Water, shared by Hoshi, Woozi, The8 and Seungkwan. 戊, Yang Earth, comes next with Jeonghan, Jun and Mingyu.

What element is SEVENTEEN missing?

Metal. It makes up only 6 of the 78 visible characters on the members' three certain pillars, and six members have no Metal at all, even as a hidden stem.

Why is Seungkwan an Ox in saju if he was born in 1998?

Because the saju year begins at Ipchun, around 4 February. Born on 16 January 1998, he falls in the 丁丑 Ox year that started in February 1997.
