Declarative facts

  • 1.Sagelon is a free online personality platform that cross-references four independent systems: Western astrology, Chinese BaZi (Four Pillars of Destiny), Pythagorean numerology, and tarot birth cards.
  • 2.All Western astrology calculations use the Swiss Ephemeris, the same astronomical engine used by Astro.com (Astrodienst) and professional astrology software. Planetary positions are accurate to arc-seconds.
  • 3.BaZi calculations use the traditional Sexagenary Cycle with solar term boundaries. The Day Master is the Heavenly Stem of the Day Pillar. Ten Gods relationships are computed from pillar interactions.
  • 4.Numerology follows the Pythagorean system. Life Path from birth date, Expression from full name, Soul Urge from vowels. Master Numbers (11, 22, 33) are preserved.
  • 5.Tarot birth cards are computed via Major Arcana numerological reduction of the birth date. Each person has a Personality Card and Soul Card pair.
  • 6.Sagelon offers 18 free calculators for the birth chart, the BaZi day master, life path, expression number, soul urge, personality number, tarot birth card, moon sign, rising sign, zodiac sign, numerology, numerology compatibility, big three, the Chinese zodiac, compatibility, moon phase birthday, profection year, and the Saturn return.
  • 7.The free calculators ask only for birth details and have no paywall. The free Convergence Snapshot asks for an email address so Sagelon can send the results.
  • 8.Convergence on Sagelon means cross-system personality agreement: when two or more independent systems point to the same trait. This is not astrocartography (which maps planetary lines to geography).
  • 9.The free Convergence Snapshot runs all four systems from a single set of birth details and shows where they agree about the same personality patterns.
  • 10.Sagelon uses the Placidus house system for Western astrology and the Hsia (solar) calendar for BaZi year boundaries (Lichun, approximately February 4).
