Critics of astrology often argue that "astrologers," a loosely defined group that includes dabblers, serious students, and practicing astrologers, are uniformed in regard to the existence of two zodiacs.

They may be right about the first group, but certainly not about the second and third. For the past 40 years, at least, most serious astrology books have drawn attention to the tropical-sidereal debate when the topic of the zodiac is discussed. There is no excuse for anyone who considers themselves an "astrologer" today to be ignorant of the existence of this complex issue.

However, exactly what are the differences between each zodiac, expecially in regard to symbolic delineation purposes, is a topic that has not been adequately addressed. And so we are still left with a deep and unresolved controversy that haunts our field of study.


According to her family records, Maria Antonia Habsburg was born November 2, 1755 at 7:30 p.m. in Vienna, Austria. If a horoscope is cast for these data using 7:30 p.m. Central European Time, it will not produce the right horoscope because clocks in 1755 were not set to that time standard. Central European Time and the other time zones used today were not employed until late in the Nineteenth Century.

If the local mean time of Vienna is substituted for Central European Time, Maria's horoscope will still be wrong because local mean time was not used anywhere as a civil standard until 1780 at Geneva, Switzerland, and nowhere else until London adopted local mean time in 1792; the rest of England did not follow suit at once..
