How birth-date compatibility works

Three signals need only a date. This test reads all three, then combines them.

Elemental temperament

Your sun sign maps to an element, fire, earth, air or water. Some pairs feed each other (a classic spark-and-fuel match), some share instincts, some pull in opposite directions under pressure.

Chinese zodiac

Your birth year gives your animal. The system groups animals into trust circles (trines) that back each other naturally, and clash pairs whose instincts fight at the worst moments.

Life-path numbers

Reduce a birth date and you get a life-path number, the numerology read on how someone moves through life. Shared or complementary numbers add a quiet layer of ease.

Questions people ask

How accurate is a birth-date compatibility test?

From two dates alone, this is a first read, not the whole story. It cross-references three date-only signals (element, Chinese zodiac, life path), so it is genuinely indicative and far more grounded than a single star-sign horoscope. The full DECODE Pair report reads five systems in depth for both people, plus the exact dynamic between you.

What do I need to run it?

Just two birth dates. No names, no birth times, no sign-up, no payment. Everything runs in your browser and nothing is stored or sent.

Is this just star-sign compatibility?

No. Star sign is one of three inputs. The test also reads Chinese zodiac trines and clashes and your life-path numbers, then combines them into one chemistry read. The full report adds Human Design and BaZi.

How is the full Pair report different?

The full report decodes both people across all five systems in depth, cross-checks them, and maps exactly where you click, where you clash, how each of you communicates and decides, and what each of you needs to feel met.
