Date precision and interpretation limits
This example begins with a sourced date and birthplace. Planetary sign ranges can be checked over a broad UTC window, but neither a house placement nor a personal claim about Maathai follows from those data alone.
Planetary sign range for the recorded date
The possible signs cover hourly positions across the recorded date and every civil-day UTC offset from +14 to −12. Without a verified birth hour or offset, a body that crosses a sign boundary remains unresolved.
| Body | Possible signs | Reading note |
|---|---|---|
| Sun | Aries | Same sign in all hourly samples |
| Moon | Capricorn / Aquarius | Birth hour or offset may change the sign |
| Mercury | Pisces | Same sign in all hourly samples |
| Venus | Taurus | Same sign in all hourly samples |
| Mars | Taurus / Gemini | Birth hour or offset may change the sign |
| Jupiter | Aries | Same sign in all hourly samples |
| Saturn | Taurus | Same sign in all hourly samples |
Geocentric tropical positions. A sign shown twice cannot be narrowed down without a documented birth time and historical UTC offset.
