ILLIT · Bias match
Korean Saju reads compatibility from two birth charts — not sun signs. Enter your birthday and see your match type with Iroha in 10 seconds. Free.
Iroha is The Hilltop Oak — a Yang Wood Day Master (the core element of their Four Pillars). That's the chart we'll read yours against.
| Pillar | Stem | Branch |
|---|---|---|
| Year | 丁 Jeong · Yin Fire | 亥 Hae · Pig · Water |
| Month | 癸 Gye · Yin Water | 丑 Chuk · Ox · Earth |
| Day | 甲 Gap · Yang Wood | 戌 Sul · Dog · Earth |
| Hour | Unknown (birth time not public) | |
| Wood | Fire | Earth | Metal | Water |
|---|---|---|---|---|
| 1 | 1 | 2 | 0 | 2 |
Iroha was born on a solar-term day, so the year and month pillars depend on the birth hour: 丁亥 (Jeong-Hae) year and 癸丑 (Gye-Chuk) month before 20:04 Korea time, 戊子 (Mu-Ja) year and 甲寅 (Gap-In) month from 20:04. The table shows the noon chart, which Palja uses when the birth time is unknown.
Birthday: Korean Wikipedia gives this date (checked October 20, 2026). Pillars: Palja's manseryeok engine, year and month switching at the exact solar term.

Iroha was born on February 4, 2008. Iroha's birth time is not public, so Iroha's Saju chart has three pillars (year, month and day) instead of four.
Iroha's pillars are 丁亥 (Jeong-Hae) year, 癸丑 (Gye-Chuk) month and 甲戌 (Gap-Sul) day (noon chart; born on a solar-term day). The Day Master is Yang Wood (甲 Gap), and the six characters hold 2 Earth, 2 Water, 1 Wood, 1 Fire and 0 Metal.
Saju (사주, "Four Pillars") maps your birth date and time to five elements. Compatibility compares two people's day pillars — the part that rules relationships — to score chemistry, stability, growth and friction. Iroha's chart is fixed; yours is calculated live in your browser (your birthday never leaves your device).
