How does Saju compatibility work?

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