1. Solar-Term Adjustment
We calculate true solar time using your longitude and the Equation of Time (EoT), applying classical solar-term rules (JieQi) so the sun’s position at birth is exact.
2. Hidden Stems Calculation
Each branch (year/month/day/hour) carries hidden stems, each worth 0.5★, to capture deeper influences.
3. Seasonal Modifiers
Elements in their native season gain +1★; out-of-season elements receive −1★, reflecting the natural ebb and flow of qi.
4. Star Scoring
We calculate your element’s strength by adding:
- Visible stems (0–2 points)
- Hidden stems (0.5★ each)
- Seasonal modifier (+1★ if in-season, –1★ if out-of-season)
- Day-Master bonus (+1★ if it’s your core element)
So your final score can range below 0 to above 5, reflecting the true mix of influences.
