Moon Phase Compatibility Calculator
Enter two birthdays to see each person's moon phase and how they pair — a playful moon soulmate test to spark a little reflection.
How moon phase compatibility works
The moon moves through eight phases roughly every 29.5 days. We find the phase on each birthday and compare them on the lunar wheel. Complementary phases — the same or opposite — tend to read as an easy match, while quarter-turn pairings blend similarity with contrast.
FAQ
What is moon phase compatibility?
It pairs the moon phase on each person's birthday and reads how those phases complement each other. It's a light, shareable way to think about a connection — not an astrological certainty.
How is the compatibility score calculated?
We compute each birthday's moon phase, then score how the two phases sit on the lunar cycle. Same and opposite phases read as especially complementary. The result is fixed and repeatable for entertainment.
Is the moon phase soulmate test accurate?
It's for fun and reflection. It does not predict whether two people are soulmates or what will happen in a relationship.
