The story behind Birth Time
Precise birth times became more available with modern records, while older charts often required rectification or approximation.
Birth Time in spiritual tradition
Spiritually, Birth Time reminds the reader that precision should serve truth, not false certainty.
Why Birth Time matters
Birth Time matters because the sky keeps moving. A few minutes can shift angles, house cusps, and sometimes the Moon's degree enough to change interpretation.
