Calculations run in this browser with Astronomy Engine 2.1.19 (MIT license). Times use the selected IANA zone or a documented UTC offset. For ancient records, a modern city zone does not establish the historical clock convention. Gregorian and Julian dates are explicit; output dates and the lunar calendar use Gregorian. There is no modern-era date cutoff, but accepting a distant date is not a guarantee of modern-era precision.

City names, coordinates and time zones derive from GeoNames, under CC BY 4.0. Dataset notice. City input is resolved locally, and is neither saved nor sent to a location service.

The zodiac wheel shows tropical geocentric longitudes. Ascendant and Midheaven depend on the selected time and coordinates; Whole Sign supplies the house geometry. The position list gives each body’s house and motion. Major aspects are ordered by distance from exact.
