One birth moment.
Many ways to understand it.

Begin with your name and date of birth. Adding your exact birth time and birthplace allows us to create a more detailed BaZi chart and reconstruct the sky above you when you were born. If you do not know your birth time, you can still discover your core AsterNym identity, name story, zodiac signs and numerology — features that depend on the missing information are identified as unavailable or approximate. Your information remains on your device unless you choose to create an account. Accounts are optional and available only to people aged 18 or older.

AsterNym processes several layers of information: your name — its linguistic origins, meanings and popularity; Western astrology — your zodiac sign and seasonal placement; Chinese astrology — your zodiac animal and its traditional qualities; BaZi — your year, month, day and hour pillars, Day Master and elemental balance; numerology — the patterns calculated from your name and birth date; and astronomy — the real positions of stars and constellations above your birthplace. Each method contributes something different. AsterNym brings the results together instead of treating one system as your entire identity.

At the centre of your profile is one of sixty AsterNym archetypes. Our system crosses your elemental signature with your Life Path — 5 elemental signatures × 12 Life Paths = 60 core identities. Your element describes the texture of your energy. Your Life Path describes its direction. Their meeting point becomes your AsterNym — such as the Evergreen Architect, Radiant Seeker or Tidal Visionary. Your name, zodiac signs, BaZi chart and other results add further detail around that core identity.

The element comes from your Day Master — the heavenly stem of your BaZi day pillar, the reference point the whole chart is judged against. The Life Path is your birth date reduced the Pythagorean way. Both are fixed at birth, so your identity never changes. What does change is the weather around it: in BaZi, ten-year Luck Pillars (Da Yun) and annual cycles bring new elements that interact with your chart, so how your identity is currently expressed shifts with the seasons of your life. A Steadfast Architect in a Fire decade builds louder and faster than the same Architect in a Water decade.

Your free AsterNym print presents the essential pattern in a format you can save and share. Your complete report explores the system in greater depth, including your personal spectrums, elemental balance, Four Pillars, hidden stems and Ten Gods. These are interpretive tools: you are invited to consider what resonates, question what does not and use the reading for reflection rather than instruction. Your daily reading is recalculated for each date and can be viewed through either Western or Chinese astrology.

Using established astronomical catalogue and ephemeris data, AsterNym calculates which stars were above your local horizon at the date, time and place of your birth. The qualifying star in our catalogue nearest the point directly above you — the zenith — becomes your Birth-Sky Star. You can inspect its scientific identifier, coordinates and position. Where reliable historical information is available, we also show the recorded or reconstructed weather conditions around your birth time and identify the source.

Compare your AsterNym with friends, partners and romantic interests to see where your symbolic patterns align or differ. You can also compare your profile with public figures whose birth information comes from cited public sources. A compatibility score is an AsterNym interpretation — not a prediction of whether a relationship will succeed.

Every star offered through AsterNym is a real astronomical object with scientific coordinates. You can give it a symbolic name and dedication for yourself or someone important to you, then find it again on the AsterNym Galaxy Map. The dedication is recorded permanently within the private AsterNym registry. It does not change the star’s scientific designation, create legal ownership or receive recognition from the International Astronomical Union. We explain that beside the purchase — not hidden in the small print.
