Positions come from JPL/Standish orbital elements with fitted perturbation series, and a truncated ELP2000-82B series for the Moon. Checked against Swiss Ephemeris over 400 random charts, 1900–2060: worst deviation 26″ for the Moon, under 11″ elsewhere, under 5″ on house cusps. Lunation times land within 17 seconds; eclipse detection scored 72/72 across 2015–2031 with no false positives. Returns and transit dates are found by root-solving on the same ephemeris, so retrograde triple passes are counted properly. Tropical zodiac, apparent positions, nutation and annual aberration included.

The interpretation is writing, not astronomy. A description feeling accurate is usually the Barnum effect: statements open enough will fit anyone. This is for entertainment. It is not a personality assessment, a health tool, or a way to make decisions.
