Calculates the zodiac sign of the sun.
procedure SunZodiac(date:TDateTime): TZodiac;
Description Calculates the zodiac sign where the sun is located at the date. This however does not mean that the sun is in the astronomical area of that star sign, it is just the ecliptic longitude measured from the vernal equinox partitioned in areas of 30°. Due to the precession the equinox is moving, it is now at the boundary of Aquarius and Pisces, but the zodiac associated with it is still Aries where the equinox was at time of the Babylonian.
Hint The beginning of the zodiacs are calculated by the major solar terms.
