Signs are computed from the Sun’s position with the astronomy-engine ephemeris, checked against Swiss Ephemeris. Birth dates and places come from Wikidata. A sign is shown beside a name only when it holds for the whole of the birth date; where it does not, both possibilities are given. How to read a birth chart.
