Although the zodiac remains the basis of the ecliptic coordinate system in use in astronomy besides the equatorial one,  the term and the names of the twelve signs are today mostly associated with horoscopic astrology. The zodiac of a given planet is the band that contains the path of that particular body; e. By extension, the "zodiac of the comets" may refer to the band encompassing most short-period comets.
Zodiac Sign Dates: What Are The Dates for Every Star Sign?
The division of the ecliptic into the zodiacal signs originates in Babylonian " Chaldean " astronomy during the first half of the 1st millennium BC. The zodiac draws on stars in earlier Babylonian star catalogues, such as the MUL. LUL "The Crayfish," among others. Around the end of the 5th century BC, Babylonian astronomers divided the ecliptic into 12 equal "signs", by analogy to 12 schematic months of 30 days each.
According to calculations by modern astrophysics, the zodiac was introduced between BC and probably within a very few years of BC. The divisions don't correspond exactly to where the constellations started and ended in the sky; this would have resulted in an irregular division. The Sun in fact passed through at least 13, not 12 Babylonian constellations.
In order to align with the number of months in a year, designers of the system omitted the major constellation Ophiuchus. Changes in the orientation of the Earth's axis of rotation also means that the time of year the Sun is in a given constellation has changed since Babylonian times.
However, Babylonian techniques of observational measurements were in a rudimentary stage of evolution. In Babylonian astronomical diaries , a planet position was generally given with respect to a zodiacal sign alone, less often in specific degrees within a sign.
Knowledge of the Babylonian zodiac is also reflected in the Hebrew Bible ; E. Bullinger interpreted the creatures appearing in the book of Ezekiel as the middle signs of the 4 quarters of the Zodiac,   with the Lion as Leo , the Bull is Taurus , the Man representing Aquarius and the Eagle representing Scorpio. Martin and others have argued that the arrangement of the tribes around the Tabernacle reported in the Book of Numbers corresponded to the order of the Zodiac, with Judah , Reuben , Ephraim , and Dan representing the middle signs of Leo, Aquarius, Taurus, and Scorpio, respectively.
Such connections were taken up by Thomas Mann , who in his novel Joseph and His Brothers attributes characteristics of a sign of the zodiac to each tribe in his rendition of the Blessing of Jacob. Hellenistic astrology derived in part from Babylonian and Egyptian astrology. The Dendera zodiac , a relief dating to ca. The earliest extant Greek text using the Babylonian division of the zodiac into 12 signs of 30 equal degrees each is the Anaphoricus of Hypsicles of Alexandria fl.
Hipparchus's lost work on precession never circulated very widely until it was brought to prominence by Ptolemy,  and there are few explanations of precession outside the work of Ptolemy until late Antiquity, by which time Ptolemy's influence was widely established. The Hindu zodiac uses the sidereal coordinate system , which makes reference to the fixed stars. The Hindu zodiac, being sidereal, does not maintain this seasonal alignment, but there are still similarities between the two systems. The Hindu zodiac signs and corresponding Greek signs sound very different, being in Sanskrit and Greek respectively, but their symbols are nearly identical.
This included magical uses of the zodiac, as found, e. Mughal king Jahangir issued an attractive series of coins in gold and silver depicting the twelve signs of the Zodiac. An example of the use of signs as astronomical coordinates may be found in the Nautical Almanac and Astronomical Ephemeris for the year The "Longitude of the Sun" columns show the sign represented as a digit from 0 to and including 11 , degrees from 0 to 29, minutes, and seconds.
The zodiac symbols are Early Modern simplifications of conventional pictorial representations of the signs, attested since Hellenistic times. But note that the Sanskrit and the name equivalents after c.
Also, the "English translation" isn't usually used by English speakers. Latin names are standard English usage. The zodiacal signs are distinct from the constellations associated with them, not only because of their drifting apart due to the precession of equinoxes but also because the physical constellations take up varying widths of the ecliptic, so the Sun is not in each constellation for the same amount of time. The zodiacal signs are an abstraction from the physical constellations, and each represent exactly one 12th of the full circle, or the longitude traversed by the Sun in about The path of the Sun passes through 13 constellations recognized by ancient Babylonian, Greek, and Roman astronomers including in Ptolemy 's Almagest   and the modern International Astronomical Union.
Because the Babylonians had a month lunar calendar, they chose and divided up the year evenly. The 13th was left out: Ophiuchus , the bottom part of which interjects between Scorpio and Sagittarius. Occasionally this difference between the astronomical constellations and the astrological signs is mistakenly reported in the popular press as a "change" to the list of traditional signs by some astronomical body like the IAU, NASA , or the Royal Astronomical Society.
For example, in drawing a distinction between astrology and scientific astronomy, NASA notes that "No one has shown that astrology can be used to predict the future or describe what people are like based on their birth dates. Some "parazodiacal" constellations are also touched by the paths of the planets, leading to counts of up to 25 "constellations of the zodiac".
Some other constellations are also mythologically associated with the zodiacal ones: Piscis Austrinus , The Southern Fish, is attached to Aquarius. In classical maps, it swallows the stream poured out of Aquarius' pitcher, but perhaps it formerly just swam in it. Aquila , The Eagle, was possibly associated with the zodiac by virtue of its main star, Altair. The following table compares the Gregorian dates on which the Sun enters:.
The theoretical beginning of Aries is the moment of vernal equinox , and all other dates shift accordingly. The precise Gregorian times and dates vary slightly from year to year as the Gregorian calendar shifts relative to the tropical year. Except for and , the vernal equinox has started on 20 March since , and is projected to until Because the Earth's axis is at an angle, some signs take longer to rise than others, and the farther away from the equator the observer is situated, the greater the difference. Thus, signs are spoken of as "long" or "short" ascension.
The zodiac system was developed in Babylonia , some 2, years ago, during the " Age of Aries ". Contemporary use of the coordinate system is presented with the choice of interpreting the system either as sidereal , with the signs fixed to the stellar background , or as tropical , with the signs fixed to the point vector of the Sun at the March equinox.
