A famous date, an undocumented hour
Einstein is a useful example of a common archive problem: the public biographical record gives a precise calendar day and city, while a chart with an Ascendant would require a separately verified clock time.
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 | Pisces | Same sign in all hourly samples |
| Moon | Scorpio / Sagittarius | Birth hour or offset may change the sign |
| Mercury | Aries | Same sign in all hourly samples |
| Venus | Aries | Same sign in all hourly samples |
| Mars | Capricorn | Same sign in all hourly samples |
| Jupiter | Aquarius | Same sign in all hourly samples |
| Saturn | Aries | 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.
