Don’t worry, your sign will not change as a result of the new zodiac dates. This is an example of a modal window.

How often do the signs of the zodiac change?
Is that to say that your zodiac sign changes each year? No, it’s more like once every 30 years or so. (Thank G, you’ve got some time to think about it.) “Each sign has 30 degrees, and the advanced sun moves less than a degree per year, so this shift is really slow,” Montfar explains.
What are the 2020 zodiac signs?
According to Western astrology, there are 12 zodiac signs (meaning “signs of the zodiac”) “There are 13 constellations that the Sun travels through each year, not just a circle of animals:
Cancer, Leo, Virgo, Libra, Scorpio, Ophiuchus, Sagittarius, Capricorn, Aquarius, and Pisces.
Unfortunately, astrologers’ dates given to star signs are incorrect, in addition to neglecting Ophiuchus. Here’s what astrology claims happens in the night sky, based on its line-of-sight theory “Insights into people’s moods and fortunes:
The Sun’s position in the sky according to astrology (wrong)
Here’s where and when astrologers pretend the Sun is in the sky, dictating what the majority of people believe their birth star sign is:

- January 20-February 18 is the sign of Aquarius.
- February 19March 20: Pisces

- Scorpio: 23rd October 21st November
- November 22December 21: Sagittarius
The Sun’s actual position in the sky (correct)
This is when the Sun is in the constellations, hence your true “star sign,” with some astrological overlap and plenty of surprises:
- January 20February 16: Capricorn
- Aquarius: February 16th through March 11th
- Pisces (March 11April 18) is a water sign.
- April 18May 13: Aries
- May 13June 21: Taurus

- 30th of October 23rd of November
- Scorpio: November 23November 29 (just a week!) Scorpio: November 23November 29 (just a week!) Scorpio: November 23
- Ophiuchus (not an astrological sign of the zodiac, but very real!): November 29December 17 (not an astrological sign of the zodiac, but very real!)
- December 17th January 20th, Sagittarius
Because the Sun isn’t in the sign of the zodiac when astrology says it is, your horoscope is probably incorrect. Of course, none of this matters, but knowing why will help you have a better knowledge of the globe you live on.
Do the signs of the zodiac change throughout time?
Because of a 26,000-year-old process known as “precession,” the stars appear to migrate over time. The wobble in the Earth’s rotation is to blame for this.
What are the dates of Ophiuchus?
The Serpent Bearer, Ophiuchus, is frequently referred to as the 13th or Forgotten Constellation of the Zodiac. Because the sun passes in front of Ophiuchus every year between November 30 and December 18, this is the case. Despite this, no one ever claims to have been born when the sun was in Ophiuchus.
What are astrological signs and what do they mean? The 12 signs of the tropical zodiac represent 30-degree sections of the sky that are equally proportioned. That’s why, for example, the sun only appears in front of each zodiac sign for about a month at a time. Meanwhile, the sun passes in front of the constellations for varied lengths of time, for example, around 1 1/2 months in front of the constellation Virgo and about a week in front of the constellation Scorpius.
What are the different types of astronomy constellations? Ancient stargazers identified patterns in the stars, gave them names, and linked them to legends and mythology. The International Astronomical Union (IAU) established formal constellation borders in the early twentieth century. The constellations come in a variety of sizes and shapes. The zodiac constellations are those through which the sun, moon, and planets all pass. We’ve had 12 zodiac constellations for as long as anyone can remember. Their names (roughly) correspond to the 12 zodiac signs.
There are 13 zodiac constellations if you include Ophiuchus, which also holds the sun within its borders for part of the year.
Ophiuchus a short hop north of Antares
On these July nights, you can glimpse Ophiuchus the Serpent Bearer. The stars are faint, so you’ll need a dark sky to see them. From the Northern Hemisphere, look for Ophiuchus in the south at nightfall. Around mid-evening, look more overhead from the Southern Hemisphere.
Antares, a brilliant red star in the constellation Scorpius the Scorpion, can aid in the search for Ophiuchus. Ophiuchus can be seen a short distance north of Antares.
The brightest star in Ophiuchus is Rasalhague, a 2nd-magnitude star that highlights Ophiuchus’ head. In the Ophiuchus chart below, look for Rasalhague. Rasalhague, on the other hand, isn’t nearly as bright as Antares.

What is the correct pronunciation of Ophiuchus?
Ophiuchus is pronounced /fijuks/ in the International Phonetic Alphabet (IPA). Ophiuchus is pronounced “oh-FEW-kuss” in simple old English.
What is the total number of zodiac signs?
Each of the zodiac’s 12 astrological signs is said to occupy 1/12 (or 30) of its vast circle. These symbols no longer match to the astrological constellations where the Sun can be found.
