Do not infer a birth hour from a life event
The National Baseball Hall of Fame records Robinson’s date and Cairo birthplace. His historic baseball debut is a precisely dated public event, but it cannot establish the clock time of his birth decades earlier. The archive therefore presents sign ranges without a rising sign or houses.
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 | Aquarius | Same sign in all hourly samples |
| Moon | Capricorn / Aquarius | Birth hour or offset may change the sign |
| Mercury | Capricorn | Same sign in all hourly samples |
| Venus | Aquarius | Same sign in all hourly samples |
| Mars | Pisces | Same sign in all hourly samples |
| Jupiter | Cancer | Same sign in all hourly samples |
| Saturn | Leo | 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.
