K-pop Idol Astrology

Birth charts, ideal types and couple compatibility for K-pop idols, read through Korean astrology (Saju, 사주). Every chart comes from the member's documented birth date.

Birth Charts사주 · BIRTH CHART

Who each idol is. A full Saju reading of the whole chart — year, month and day pillars together, with the day master as the lens.

Ideal Type배우자궁 · SPOUSE PALACE

What each idol is drawn to in a partner. Read from one place in that chart — the day pillar, whose branch is the spouse palace.

Couple Compatibility궁합 · K-POP EX-COUPLES

K-pop couples who have since broken up, read as two charts side by side. What pulled them together, and what the charts say pulled them apart.

The one character every chart starts with. All ten explained, each through two idols who share it — and a free reading to find yours.

COMMON QUESTIONS

Do K-pop idols share the same day master?

Yes, and more often than people expect. There are only ten day masters, so across the 49 idols charted here every one of the ten carries at least two — the smallest group is 庚 yang Metal with two, the largest is 甲 yang Wood with ten.

What is a day master in Korean astrology?

The day master is the single character that represents the self in a Korean astrology chart. It is the heavenly stem of the birth-day pillar, and it is the lens the rest of the chart is read through. There are ten, one for each combination of the five elements with yin or yang polarity. All ten, explained →

How are these K-pop idol birth charts calculated?

From each idol's documented birth date, using the classical boundaries rather than the calendar ones. The year turns on 立春 in early February, so a January birthday belongs to the previous year, and each month turns on its solar term rather than on the first. Birth times are not public, so these are three-pillar charts.

What is the difference between an idol's birth chart reading and their ideal type?

The birth chart reading works from the whole chart — the year, month and day pillars read together — and describes who someone is. The ideal type is read from one specific place in that same chart: the day pillar, whose branch is the spouse palace, 배우자궁. One chart, two different questions.

Can Korean astrology read a K-pop couple's compatibility?

Yes. Couple compatibility, called gunghap (궁합), sets two birth charts side by side: how the birth years and months interact, what each chart looks for in a partner, and whether the two temperaments steady each other or wear each other down. The couple readings here cover K-pop pairs who have since broken up, so the charts can be read against what actually happened. All couple readings →

Why do these idol charts show three pillars instead of four?

A complete Korean astrology chart has four pillars: year, month, day and hour. The hour pillar requires an exact birth time, which K-pop idols do not make public. These readings use the three pillars a birth date establishes and say so, rather than filling the gap with a guess.
