Tropical Astrology is a type of astrology based on a zodiac whose points of reference are the tropics. The word tropic comes from the Greek for "turning point," and originally meant the point at which the sun at sunrise and sunset appears to turn, and to move north along the horizon after the winter solstice or south after the summer solstice. Astrology refers to any of several systems, traditions or beliefs in which knowledge of the apparent positions of celestial bodies is held to be useful in understanding, interpreting, and organizing knowledge about human affairs and events on Earth. ... Zodiac signs, 16th century , medieval woodcuts The zodiac is an historical astronomical coordinate system based on the division of the ecliptic[1] into twelve equal signs, each sign defining a specific ecliptic longitude of 30 degrees. ... The tropics are the geographic region of the Earth centered on the equator and limited in latitude by the two tropics: the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere. ...

Tropical astrology is based on the idea that early astrologers (mid-to-late first millennium BCE) defined the star signs according to the seasons in which the sun rose in them; it wishes to preserve the seasonal associations of those star signs by laying out new horoscopes against a first-millennium sky. For tropical astrologers therefore it is irrelevant that the solsticial points (tropics) have drifted from one constellation to another over the millennia, due to the precession of the equinoxes. The underlying philosophy remains unchanged in spite of precession, because it is based on the earth's (and therefore our) relationship to the sun, not to the stars. The names of the zodiacal constellations that became the star signs are supposed to suggest the characteristics of (the sun in) each segment of the year. Thus, Aries (House 1), representing the sun just returning to the northern hemisphere at the vernal equinox, symbolises unruly beginnings; Leo (House 5), representing the powerful sun of mid-summer, symbolises fertility and self-display; Sagittarius (House 9), representing the retreating or meditative sun close to the winter solstice, symbolises the search for understanding. The Common Era (CE), sometimes known as the Christian Era or Current Era, is the period of measured time beginning with the year 1 (the traditional birthdate of Jesus) to the present. ...

In its emphasis on the symbolic or metaphorical meaning of the star signs tropical astrology differs from sidereal astrology which claims intrinsic meaning for the star signs and wishes to preserve those meanings by laying out horoscopes against the actually occurring sky. In language, a metaphor (from the Greek: metapherin) is a rhetorical trope defined as a direct comparison between two or more seemingly unrelated subjects. ... Sidereal astrology is the practice by some western and all Indian astrologers of basing their study of the sky on the actual position of the planets in relation to the starry background. ...


In the tropical zodiac the sun at the vernal equinox is considered to be in the first degree of the star sign Aries. This is because when astrology was being developed by the Babylonians and the Hellenistic Greeks the sun actually was in the constellation Aries at the vernal equinox (whereas now it is in Pisces). Even by the time the earliest horoscopes were written, however, in the fifth century BCE, the equinoctial point had drifted -- to about the 28th degree of Aries. The last time the vernal equinox was in the first degree of Aries was around 1900 BCE, give or take a hundred years, depending on how you read the ecliptic.

The tropical zodiac in astrology is largely exclusive to The Americas and Western European astrologers. Some Western astrologers choose to practice sidereal astrology, and criticise the tropical approach as erroneous because it does not align with the actual position of the stars. Siderial astrologers also point out the absurdity of applying northern hemisphere seasons to the whole planet when there are now large populations within the southerm hemisphere who experience seasons six months apart from those in the north. Tropical astrologers counter that there may be many ways of interpreting the relationship of the current night sky to the pattern of star signs. This is a long running dispute within Western astrology. The Americas (sometimes referred to as America) is the area including the land mass located between the Pacific Ocean and the Atlantic Ocean, generally divided into North America and South America. ...

Vedic Cosmologist Patrizia Norelli-Bachelet writes that a correct understanding of both the tropical and the sidereal zodiac are necessary for tracking and understanding the movement of the earth and its species.

astrology (2044 words)
The sidereal year is longer than the tropical year because of the precession of the equinoxes, i.e., the slow westward shift of the equinoctial points along the plane of the ecliptic at a rate of 50.27 seconds of arc per year, resulting from precession of the earthÂ’s axis of rotation.
Sidereal astrology uses the actual constellation in which the sun is located at the moment of birth as its basis; tropical astrology uses a 30-degree sector of the zodiac as its basis.
Tropical astrology is the most popular form and it assigns its readings based on the time of the year, while generally ignoring the positions of the sun and constellations relative to each other.
