, and each sign has its own set of strengths and weaknesses, as well as unique characteristics, desires, and perspectives on life and people. By calculating the position of the planets, as well as the Sun and Moon, on the Ecliptic at the time of birth. Astrology can reveal a person’s basic personality traits, preferences, weaknesses, and fears.

What do the signs of the zodiac mean?
1a: an imaginary band in the heavens centered on the ecliptic that contains all of the planets’ apparent paths and is divided into 12 constellations or signs, each of which extends 30 degrees in longitude for astrological purposes. b: a representation of the zodiac signs and their symbols.
What are the origins of the zodiac signs?
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, 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 one-tenthor almost a month around the sky to the west.
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.

Is astrology a true science?
Astrology is a collection of belief systems that assert that there is a connection between astrological phenomena and events or personality traits in the human world. The scientific community has dismissed astrology as having no explanatory power for describing the universe. Scientific testing has discovered no evidence to back up the astrological traditions’ premises or alleged effects.
People believe in astrology for a variety of reasons.
Self-Discovery It’s likely that people study astrology in order to gain a better understanding of themselves and increase their self-awareness. Astrology has been shown in studies to significantly impact and even validate a person’s self-concept, as well as improve their confidence in their unique characteristics.
