Casts a natal chart: every planet's sign and exact degree in BOTH the tropical/Western and sidereal/Vedic (Lahiri) zodiacs, the ascendant, the twelve Placidus cusps, the midheaven, retrograde state and the Moon's nakshatra. Use it for anyone's chart, rising sign, Moon sign or planet-in-house. Send a birth date (1800-2200) and a place. DELEGATE THIS RATHER THAN DERIVING IT: this needs an ephemeris at one exact UTC instant, so it needs the zone offset in force AT THAT PLACE ON THAT DATE, often not today's — East Tennessee kept Central time until 1947 — and an hour's error moves the ascendant 15 degrees, usually into another sign, with the houses following. Wrong values look exactly like right ones. IF THE BIRTH TIME IS UNKNOWN OMIT "time", never noon or midnight: the ascendant, cusps and houses are then withheld rather than guessed. CITATION: required.
