Moon Phase Compatibility
Two birth dates, two natal moon phases. See how your lunar rhythms meet — and where they pull against each other.
How the match is read
Find each natal phase
We count the days between each birth date and the nearest new moon, then place it on the 29.53-day lunar cycle — landing each person on one of eight named phases.
Measure the distance
The gap between the two phases is the whole story. Neighbours flow; a quarter-turn apart builds tension; opposite phases create pull; the same phase mirrors.
Read the dynamic
Each pairing gets one of five readings — Flow, Building, Stretch, Polar or Mirror — with the specific gift and the specific blind spot it tends to carry.
What each phase brings to a relationship
Your natal moon phase is the emotional rhythm you were born into — how you start, sustain and let go. Here is what each one carries.
New Moon
starts things, sees possibility, loves fresh beginnings.
Waxing Crescent
grows through connection, curious, adjusts and learns.
First Quarter
direct, confronts problems, makes clear choices.
Waxing Gibbous
nurturing, careful, gives effort and attention.
Full Moon
magnetic, expressive, big emotional intensity.
Waning Gibbous
generous, wise, gives steady presence.
Last Quarter
knows what they need, exits clearly, values depth.
Waning Crescent
introspective, imaginative, processes inwardly.
