Rora is The Evening Sun — a Yang Fire Day Master (the core element of their Four Pillars). That's the chart we'll read yours against.

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. Rora's chart is fixed; yours is calculated live in your browser (your birthday never leaves your device).
