birthplot
Read the moment you were born,
through modern science.
Your birth, read through 12 developmental coordinates.
From your date, time, and place of birth, we compute 12 developmental-science axes grounded in psychology, behavioral economics, sociology, neuroscience, and biology — an original system that can run alongside astrology.
What you can do

Relationship with astrology
Developmental coordinate theory neither denies nor replaces astrology. Respecting astrology’s structural appeal (multi-axis symbolism, a grammar for comparing relationships, and a daily-changing read), it rebuilds — from the same inputs (date, time, and place of birth) — a parallel reference line grounded in modern scientific evidence.
About the scientific basis
Each axis lists its field, references, an effect-size guide, and caveats. In fields like psychology, behavioral economics, and sociology, effect sizes (Cohen’s d) are typically around 0.1–0.3 — statistically significant yet far from fully explaining individual differences. Please use this service only as a hint for self-understanding.
Notation policy for countries and regions
This service distinguishes countries and regions based on ISO 3166-1 alpha-2. Taiwan (TW), Hong Kong (HK), and Macao (MO) are treated as independent region codes in line with this international standard.
For historical figures, we use the current administrative names of birthplaces wherever possible and aim to maintain political neutrality. When the country name or administrative division has changed since the time of birth, we prioritize the current notation.
If any place-of-birth notation seems inaccurate or insensitive, please contact the operator. We will verify the facts and correct as necessary.
