Cha Eun-woo was born on March 30, 1997. Cha Eun-woo's birth time is not public, so Cha Eun-woo's Saju chart has three pillars (year, month and day) instead of four.
Cha Eun-woo's pillars are 丁丑 (Jeong-Chuk) year, 癸卯 (Gye-Myo) month and 辛未 (Sin-Mi) day. The Day Master is Yin Metal (辛 Sin), and the six characters hold 2 Earth, 1 Wood, 1 Fire, 1 Metal and 1 Water.
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. Cha Eun-woo's chart is fixed; yours is calculated live in your browser (your birthday never leaves your device).
