What happens when two energies meet?

It compares two people's complete birth charts — all eight characters derived from each person's birth date, time, and place — to analyze how their energies interact across personality, love, money, and daily rhythm.

Zodiac compatibility compares two of twelve sun signs. Saju compatibility compares two full Four Pillars charts with 518,400 possible combinations each, so the reading reflects the two of you specifically — not two broad categories.

Both people's birth date, birth time, and birth city. That's what the engine needs to calculate each chart precisely.

Yes. You choose one of seven relationship types — romantic partner, spouse, friend, coworker, and more — and the reading is tailored to that relationship's dynamics.

The reading still works. The hour pillar is simply left out of the calculation — the engine reads the remaining six characters honestly instead of inventing the missing pillar.
