How it works

The Palmy love compatibility calculator turns two birthdays and eight taps into one number. You also get a bond word, a green flag and six rows. It runs on sun signs, moon signs, life path numbers and how your wiring lines up. Send the link and they answer for real. Half the number is theirs to fix.

Sun sign comes straight from your birthday. It sets your element, and elements shape Chemistry and Staying power. Moon sign is worked out from your birthday at noon. The moon moves fast, so a real birth time could land it one sign over. It is our one estimate. It drives Emotional pull, feeds Trust and is part of Chemistry. Life path is a numerology number from your full birth date. Three pairs bond, two rub, the rest sit in the middle. It feeds Staying power and Trust. The four taps are head or heart, calm or electric, alone or with people, need proof or I feel it. You answer for you, then give your read on them. They drive Everyday spark and Passion and feed Trust. When they answer through the link, your guesses are swapped for their real taps.

How the score is built

Chemistry

Half is sky chemistry: your sun signs, your moon signs, and how each sun sits with the other's moon. Half is your elements. Opposite elements (fire with water, air with earth) get the biggest lift, same elements the smallest.

Passion

Mostly Chemistry with a twist. The more your first three taps differ, the higher it climbs. Opposite wiring means more charge, so a pair that agrees on everything scores calmer. The belief tap is left out.

Emotional pull

Leans almost all the way on your moons. Two moons in the same or friendly elements pull it up. A bonded life path pair adds a small push.

Everyday spark

Pure wiring. It reads how close your taps sit on head or heart, calm or electric, alone or with people. Close taps mean an easy day-to-day. The belief tap is left out on purpose.

Trust

Four things in equal parts: your moons, a bonded life path pair, how close your belief taps sit, and your everyday wiring. No single input carries it.

Staying power

Half is your life path numbers. A bonding pair gets full marks: 2 and 6, 3 and 5, or 1 and 8. Every other pair gets half. The other half is elements: same scores highest, opposites middle, different lowest.

Reading your number

Sky-high (80 and up)

Inputs line up almost everywhere. Enjoy it. Still a pattern, not a promise.

Strong (65 to 79)

Most pieces fit. One or two rows carry the story. Read those first.

Steady (50 to 64)

Real, but it takes some effort on purpose. Nothing here is broken.

Slow burn (under 50)

A row never drops under 44, so this is rare. Not yet, not no.

The one number

The engine keeps every pair between 30 and 99. The love lens rewards sky chemistry, opposite elements and a bit of different wiring. Twin Flames is the rare word. It needs 92 or more, opposite elements, and a life path bond or a sun that matches the other's moon.

Elements at a glance

Every sun sign belongs to an element. Here is how the four pair up as a match — the same relations the score uses.

Fire with…
Fire

Same fuel. Staying power runs high and your suns agree in the sky. The element half of Chemistry gets its smallest lift, so your moons decide the heat.

Earth

Different doors. Middle in our engine, half-friendly in the sky. Staying power sits lowest, so Chemistry leans on your moons.

Air

Different in our engine, friendly in the sky. Fire feeds air, so the suns lift Chemistry. Staying power is a build.

Water

Opposite wiring. Our biggest Chemistry and Passion lift. The sky calls it a square, so it pulls back some.

Earth with…
Fire

Different doors. Earth reads fire as loud, fire reads earth as slow. Middle here, half-friendly in the sky.

Earth

Same ground. Staying power scores high and the suns agree in the sky. Same elements give Chemistry its smallest lift, so look to your moons.

Air

Opposite wiring. Air names the idea, earth builds it a house. Big Chemistry lift, square in the sky.

Water

Different in our engine, friendly in the sky. Earth holds what water pours. Easy warm days, middle Chemistry.

Air with…
Fire

Different in our engine, friendly in the sky. Air keeps fire lit. Good sun chemistry; Staying power you build.

Water with…
Fire

Questions

How can it score us from just two birthdays?

A birthday gives a sun sign, a moon sign (estimated at noon) and a life path number. We compare those two by two, add your eight taps, and blend it into six rows and one number.

Which signs match best for love?

In our engine, fire with water and air with earth get the biggest chemistry lift. Fire with air and earth with water are friendliest in the sky. No pair scores badly by default.

Is zodiac compatibility accurate?

Honestly, no one can prove it is. It is a pattern language, and fun to compare notes with. Treat the score as a conversation starter.

What does the percentage actually mean?

How well your inputs line up for a love bond, from 30 to 99. Sky chemistry, opposite elements and a bit of difference in wiring push it up.

Is this pointless without a birth time?

No. Sun sign and life path are exact from the date. Only the moon is estimated, and can sit one sign over. Add a birth time in the app for the real moon.

We got a low score. Should I worry?

No. It means your inputs sit far apart on paper. Paper cannot see how you treat each other. Use it to talk about where you differ.

Can two so-called incompatible signs make it work?

Yes. Sun signs are one input of several, and no sign pair scores badly on its own. The sky and the elements can disagree about the same pair on purpose.

We have the same birthday. Does that mean anything?

Same day and year gives the same sun, moon and life path. A different year can shift the moon and the number. Same element lifts Staying power. You may share the same blind spot too.

Does this work for friends too?

Yes. Try the friendship version of this page. Same inputs, different weights, and the rows change to things like banter and loyalty.

Does the website read my palm?

No. This page never takes a palm photo. The app has the live palm scan and a daily line about your pair. It also has the three-way chat room with Palmy and Party mode. When a friend joins through your link, you both get 7 days of Plus.

What this can and can’t tell you

This tool reads patterns from birthdays and eight taps. It cannot know how you two treat each other on a bad Tuesday. It cannot tell you to date, stay or leave. A high score is a nice start, not proof. A low score is a conversation, not a verdict. For fun, not fate.
