A birth chart needs the recorded local birth date and time plus the historical UTC offset that applied at that place. Location also matters for angles, houses, and horizon-based tools. Date-only ephemeris pages can be useful when the birth time is unknown, but they cannot restore missing angles or houses.
Most Western tools use tropical, geocentric positions unless a guide specifies another viewpoint. Read each method note for its range and assumptions.
