Astrology calculators
One natal chart calculator. The Moon sign, rising sign and Big Three come from that chart, not from a quiz.
Most "calculators" on the web are twelve canned paragraphs. Astro Codes computes planetary positions from your birth date, time and city, then writes what those placements mean.
