Instants and positions come from the site's astronomy engine and its committed yearly and monthly sky catalogs — the same data behind the Almanac and the daily horoscopes. Times are universal time; in the Americas an instant can fall the evening before the date printed. Sign-by-sign notes, where present, use whole-sign solar houses. The readings are a tradition being applied, not a forecast — the methodology page sets out both halves.
