Early astronomers witnessed the Sun passing through the Zodiac signs in a year’s time, spending roughly a month in each. As a result, they determined that each constellation covers 30 degrees of the ecliptic.
However, due to a phenomenon known as precession, the positions of the constellations we see now have changed.
The zero point of the Zodiac used to designate the beginning day of spring in the Northern Hemisphere. The vernal equinox happens when the ecliptic and celestial equator collide, according to astronomers.
The zero point existed in Aries around 600 BCE, and it was known as the “first point of Aries.” (See Figure 1). The constellation Aries covered the first 30 degrees of the ecliptic; Taurus covered the next 30 degrees; Gemini covered the next 60 degrees; and so on for all twelve constellations of the Zodiac.
The Earth wobbles around its axis in a 25,800-year cycle, which ancient astrologers were unaware of. The gravitational attraction of the Moon on Earth’s equatorial bulge causes this wobble, which is known as precession.
This wobble has led the junction point between the celestial equator and the ecliptic to migrate west along the ecliptic by 36 degrees, or nearly one-tenth of the way around, over the past two and a half millennia. This indicates that, in relation to the stars beyond, the signs have moved a tenth of the way across the sky to the west, or about a month.
For example, persons born between March 21 and April 19 are considered Aries. During much of that time, the Sun was no longer in the constellation of Aries. The Sun is actually in the constellation of Pisces from March 11 to April 18! (See Illustration 2) See also Figure 3, which depicts the equinox precession from 600 BCE to 2600 CE.
The dates when the Sun is truly within the astronomical constellations of the Zodiac, as defined by contemporary constellation borders and corrected for precession, are listed in the table below (these dates can vary a day from year to year).
When precession is taken into consideration, your zodiac sign will most likely be different. And if you were born between November 29 and December 17, your zodiac sign is one you’ve never heard of before: Ophiuchus! After Scorpius, the eliptic crosses across the constellation of Ophiuchus.

What is the origin of the zodiac sign?
Babylonian astronomers split the ecliptic into 12 equal “signs” at the end of the 5th century BC, analogous to 12 schematic months of 30 days each. The first known celestial coordinate system was created when each sign contained 30 degrees of celestial longitude. According to contemporary astronomical estimates, the zodiac was first used between 409 and 398 BC, during Persian dominance, and most likely within a few years of 401 BC. Unlike modern astrologers, who place the beginning of the sign of Aries at the position of the Sun at the Northern Hemisphere’s vernal equinox (March equinox), Babylonian astronomers fixed the zodiac in relation to stars, placing the beginning of Cancer at the “Rear Twin Star” ( Geminorum) and the beginning of Aquarius at the “Rear Star of the Goat-Fish” ( Capricorni).
Since Babylonian times, the time of year when the Sun is in a certain constellation has altered due to equinox precession; the point of March equinox has moved from Aries to Pisces.
They formed an appropriate basis of reference for formulating predictions about a planet’s longitude because the divide was made into equal arcs of 30 each. However, Babylonian observational measurement techniques were still in the early stages of development. They used a group of “normal stars” near the ecliptic (9 degrees latitude) as observational reference points to help place a planet within the ecliptic coordinate system.
A planet’s location in Babylonian astrological journals was usually stated in terms of a zodiac sign alone, rather than particular degrees within a sign. When degrees of longitude were given, they were stated in relation to the 30 of the zodiacal sign, rather than the continuous 360 ecliptic. The positions of prominent astronomical phenomena were estimated in sexagesimal fractions of a degree in astronomical ephemerides (equivalent to minutes and seconds of arc). The daily locations of a planet were less important in daily ephemerides than the astrologically significant times when the planet moved from one zodiac sign to the next.
Who invented the zodiac astrological system?
Astrology is the study of celestial bodies’ movements and relative placements, which are thought to have an impact on human affairs and the natural world. The 12 zodiac signs, one of the earliest notions of astrology, were devised by the Babylonians around 1894 BC.
What is the zodiac’s age?
The 12 zodiac signs Aries (March 21-April 19), Taurus (April 20-May 20), Gemini (May 21-June 20), Cancer (June 21-July 22), Leo (July 23-Aug. 22), Virgo (Aug. 23-Sept. 22), Libra (Sept. 23-Oct. 22), Scorpio (Oct. 23-Nov. 21), Sagittarius (Nov. 22-De These Western, or tropical, zodiac signs were named after constellations and paired with dates based on their apparent relationship to the sun’s position in the sky.
By 1500 BC, the Babylonians had divided the zodiac into 12 equal signs, with constellation names that were similar to those we know today, such as The Great Twins, The Lion, and The Scales, and these were later adopted into Greek divination. These 12 signs were popularized by the astronomer Ptolemy, author of the Tetrabiblos, which became a key work in the history of Western astrology.
“Ptolemy codified the idea that there were 12 signs of the zodiac that were 30 wide and that the sun travelled through these signs on a regular basis throughout the year,” says Odenwald. According to the Oxford English Dictionary, the word “zodiac” is derived from a Greek term meaning “sculpted animal form,” and the sequence in which the signs are normally enumerated is also derived from that period.
Is astrology based on any scientific principles?
Is astrology accurate? Reading horoscopes is a popular pastime, but is there any scientific evidence that they are accurate?
When you’re enticed by a familiar interruption and your willpower weakens, problems can occur.
Every day, up to 70 million Americans consult their horoscopes. At least, that’s what the American Federation of Astrologers claims. According to a Pew Forum on Religion & Public Life poll conducted twenty years ago, 25% of Americans believe that the positions of the stars and planets have an impact on our daily life. In 2012, the General Social Survey indicated that 34% of Americans think astrology is “extremely” or “kind of scientific,” and that the percentage of individuals who think astrology is “not at all scientific” has decreased from two-thirds to about half.
Astrology is the concept that astronomical phenomena, such as the stars over your head when you were born or the fact that Mercury is retrograde, have the potential to influence our daily lives and personality traits. Of course, this is distinct from astronomy, which is the scientific study of celestial objects, space, and the physics of the cosmos.
A particular branch of astrologyforecasting a person’s future or providing advice on everyday activities through horoscopesis gaining in popularity. The Cut, for example, recorded a 150 percent rise in horoscope page views in 2017 compared to 2016.
Clearly, a lot of people are trying to figure out how to read the stars for guidance. Understanding the positions of the stars is the foundation of astrology, which appears to be a scientific discipline in and of itself. Is there any scientific evidence that astrology has an impact on our personalities and lives?
But, since I still have five minutes of this six-minute podcast to fill, let’s take a look at how astrology has been put to the test.
What does the Bible have to say about the zodiac signs?
I believe that God created astrology as a tool for us to better understand ourselves and to use as a spiritual tool. Numerous bible texts, in my opinion, support astrology. As a Christian, I try to remember what Jesus said. “There shall be signs in the sun, moon, and stars,” Christ predicted in Luke 21:25, referring to the importance of astrology. He explains the value of astrology with his pupils, as well as how it might be used as a sign of his return. Why would Jesus provide us this critical knowledge if we are not intended to understand the energies of the planets and signs, and if he was actually against it? Just as the three wise men knew Jesus would be born under the star in the sky that led them to him lying in the manger, Jesus warned us that when he returns, there will be signals in the sky.

Is there any truth to astrology in Islam?
Astrology is the study of celestial bodies’ movements and relative placements, which are thought to have an impact on human affairs and the natural world. According to historian Emilie Savage-Smith, astrology (ilm al-nujm, “the study of the stars”) was “by far” the most popular of the “many activities aiming to predict future occurrences or perceive hidden phenomena” in early Islamic history.
Despite Islamic prohibitions, some medieval Muslims were interested in studying the apparent motion of the stars. This was partially due to their belief in the importance of the celestial bodies, and partly due to the fact that desert inhabitants frequently traveled at night and relied on knowledge of the constellations for navigation. Muslims needed to determine the time of prayers, the direction the kaaba would face, and the correct orientation of the mosque after the arrival of Islam, all of which helped give a religious impetus to the study of astronomy and contributed to the belief that the celestial bodies had an impact on terrestrial affairs as well as the human condition.
The criteria for Islam’s attitude on astrology are laid out in Islamic jurisprudence, the Quran, the Hadith, Ijma (scholarly consensus), and Qiyas (analogy). The idea is further differentiated into that which is either halal (authorized) or haram (forbidden) (forbidden). The view that astrology is forbidden by the authorities, as enshrined in the Quran and Hadith, is shared by all Islamic sects and academics.
