zodiak.info.pl

zodiak.info.pl computes astrology from astronomy with the site's own calculations, checked against Swiss Ephemeris (differences under 1.2 arcminutes in 1900–2100) and, for the Chinese calendar, day by day against the Hong Kong Observatory's tables.

Tools:

• sign_dates: when the Sun enters each sign in a year 1900–2100, to the minute.
