aespa · Bias match
Korean Saju reads compatibility from two birth charts — not sun signs. Enter your birthday and see your match type with Winter in 10 seconds. Free.
Winter is The Riverside 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 | 庚 Gyeong · Yang Metal | 辰 Jin · Dragon · Earth |
| Month | 戊 Mu · Yang Earth | 子 Ja · Rat · Water |
| Day | 甲 Gap · Yang Wood | 子 Ja · Rat · Water |
| Hour | Unknown (birth time not public) | |
| Wood | Fire | Earth | Metal | Water |
|---|---|---|---|---|
| 1 | 0 | 2 | 1 | 2 |
Birthday: Korean Wikipedia and English Wikipedia give the same date (checked October 20, 2026). Pillars: Palja's manseryeok engine, year and month switching at the exact solar term.

Winter was born on January 1, 2001. Winter's birth time is not public, so Winter's Saju chart has three pillars (year, month and day) instead of four.
Winter's pillars are 庚辰 (Gyeong-Jin) year, 戊子 (Mu-Ja) month and 甲子 (Gap-Ja) day. The Day Master is Yang Wood (甲 Gap), and the six characters hold 2 Earth, 2 Water, 1 Wood, 1 Metal and 0 Fire.
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. Winter's chart is fixed; yours is calculated live in your browser (your birthday never leaves your device).
