Deluxe Astrology's Seed Chart calculator uses NASA JPL DE431 ephemeris data to score your child's natal chart across six weighted development dimensions — Learning Style (Mercury, 3rd/9th houses), Emotional Blueprint (Moon, 4th house), Physical Constitution (Ascendant, Mars), Social Nature (Venus, 7th/11th houses), Creative Spark (5th house, Venus-Neptune), and Purpose Path (Midheaven, North Node) — producing a composite Seed Score (0-100) and plain-language parenting insights.

The Seed Chart translates your child's birth chart into a developmental framework. Rather than abstract personality descriptions, it maps planetary positions to six concrete dimensions of child development — each scored, explained in plain language, and paired with actionable parenting strategies.

Our engine uses NASA JPL DE431 ephemeris data to calculate all planetary positions at birth, then scores each dimension through weighted factors: planetary dignities, house placements, aspect patterns, and elemental balance. The result is a Seed Score (0-100) and personalised reading that grows with your child. A child with Moon in Cancer, for example, needs predictable bedtime routines and physical reassurance when upset — our Emotional Blueprint dimension maps this directly from the lunar placement and pairs it with concrete strategies you can use tonight.
