This results in the originally unified zodiacal coordinate system drifting apart gradually, with a clockwise westward precession of 1. For the tropical zodiac used in Western astronomy and astrology, this means that the tropical sign of Aries currently lies somewhere within the constellation Pisces " Age of Pisces ".

The sidereal coordinate system takes into account the ayanamsa , ayan meaning transit or movement , and amsa meaning small part , i. It is unclear when Indians became aware of the precession of the equinoxes, but Bhaskara 2 's 12th-century treatise Siddhanta Shiromani gives equations for measurement of precession of equinoxes, and says his equations are based on some lost equations of Suryasiddhanta plus the equation of Munjaala. The discovery of precession is attributed to Hipparchus around BC. Ptolemy quotes from Hipparchus' now lost work entitled "On the Displacement of the Solstitial and Equinoctial Points" in the seventh book of his 2nd century astronomical text, Almagest , where he describes the phenomenon of precession and estimates its value.
The principle of the vernal point acting as the first degree of the zodiac for Greek astronomers is also described in the 1st century BC astronomical text of Geminus of Rhodes.
Geminus explains that Greek astronomers of his era associate the first degrees of the zodiac signs with the two solstices and the two equinoxes, in contrast to the older Chaldean Babylonian system, which placed these points within the zodiac signs. Ptolemy also demonstrates that the principle of the tropical zodiac was well known to his predecessors within his astrological text, the Tetrabiblos , where he explains why it would be an error to associate the regularly spaced signs of the seasonally aligned zodiac with the irregular boundaries of the visible constellations:.
These events can be useful, for example, to estimate the cross-sectional dimensions of a minor planet , or check a star for a close companion. The Sun's placement upon the vernal equinox, which occurs annually around 21 March, defines the starting point for measurement, the first degree of which is historically known as the " first point of Aries ". Zodiac signs have never been used to determine the boundaries of astronomical constellations that lie in the vicinity of the zodiac, which are, and always have been, irregular in their size and shape.
The use of the zodiac as a means to determine astronomical measurement remained the main method for defining celestial positions by Western astronomers until the Renaissance, at which time preference moved to the equatorial coordinate system , which measures astronomical positions by right ascension and declination rather than the ecliptic-based definitions of celestial longitude and celestial latitude.
The word "zodiac" is also used in reference to the zodiacal cloud of dust grains that move among the planets, and the zodiacal light that originates from their scattering of sunlight. In Unicode, the symbols of zodiac signs are encoded in block "Miscellaneous Symbols": .

This is a concept that has been questioned and considered repeatedly. While some astrologers utilize cusps in their practices, most do not.
But if a person is born on the cusp, and truly feels the influence of two signs, how can that be explained? Our astrologer Maria Desimone offers some insight:. The concept of sign cusps not only dilutes the meaning of the Sun sign in the horoscope, but it makes absolutely no mathematical sense.

There are 30 degrees in every sign, adding up to a perfect circle containing degrees. This concept of sign cusps is a misnomer because, even if you were born on a day when the Sun changed signs, the math will be clear: your Sun will be in one sign or the other. Relating to the sign before or after your Sun sign cannot be explained because you were born on this cusp. Your Sun sign is potent, clear and bright: he knows who he is supposed to be. So, for example, if you were born on the Aries-Taurus cusp, a correct Astrology chart cast for the date, time, and location of your birth will reveal clearly whether your Sun is at the final degree of Aries or the first degree of Taurus.
If you were born when the Sun was traveling through the final degree of Aries, but can relate to Taurus qualities, it is most likely due to the fact that Mercury, Venus, Mars, your Moon, or even your Rising sign are in Taurus. But your Sun cannot be two signs. He is not having an identity crisis While most astrologers and Astrology enthusiasts will agree with this idea, there are many individuals born on the cusp who believe that they inexplicably exert a heavy blend of both zodiac signs. For those of you who identify with your cusp or are intrigued by cusps in general, we encourage you to explore and learn about each cusp and the different ways that these energies work together!
