How Skyplot works
Positions come from the open-source Astronomy Engine library and are checked against NASA JPL Horizons data. Historical daylight saving time is taken from the IANA time zone database. Astrology is a tradition of symbolic interpretation, not a science; the texts here are meant for reflection.
