is that modern astrologers haven't bothered to adjust their "angles" base on the present day position of the starts & planets, which are quite different from where they were back in the day.
Here's the dates of the signs of the zodiac based on the ancient positions:
Capricorn - December 23 - January 20
Aquarius - January 21 - February 19
Pisces - February 20- March 20
Aries - March 21 - April 20
Taurus - April 21 - May 21
Gemini - May 22 - June 21
Cancer - June 22 - July 22
Leo - July 23 -August 21
Virgo - August 22 - September 23
Libra - September 24 - October 23
Scorpio - October 24 - November 22
Sagittarius - November 23 - December 22
And here's where those signs fall in the present day:
Capricorn - Jan 20 to Feb 16
Aquarius - Feb 16 to Mar 11
Pisces - Mar 11 to Apr 18
Aries - Apr 18 to May 13
Taurus - May 13 to Jun 21
Gemini - Jun 21 to Jul 20
Cancer - Jul 20 to Aug 10
Leo - Aug 10 to Sep 16
Virgo - Sep 16 to Oct 30
Libra - Oct 30 to Nov 23
Scorpius - Nov 23 to Nov 29
Ophiuchus - Nov 29 to Dec 17
Sagittarius - Dec 17 to Jan 20
"The first day of spring in the Northern Hemisphere was once marked by the zero point of the Zodiac. Astronomers call this the vernal equinox and it occurs as the ecliptic and celestial equator intersect.
"Around 600 BCE, the zero point was in Aries and was called the "first point of Aries." The constellation Aries encompassed the first 30 degrees of the ecliptic; from 30 to 60 degrees was Taurus; from 60 to 90 degrees was Gemini; and so on for all twelve constellations of the Zodiac.
"Unbeknownst to the ancient astrologers, the Earth continually wobbles around its axis in a 25,800-year cycle. This wobble—called precession—is caused by the gravitational attraction of the Moon on Earth's equatorial bulge.
"Over the past two-and-a-half millennia, this wobble has caused the intersection point between the celestial equator and the ecliptic to move west along the ecliptic by 36 degrees, or almost exactly one-tenth of the way around. This means that the signs have slipped one-tenth—or almost one whole month—of the way around the sky to the west, relative to the stars beyond.
"For instance, those born between March 21 and April 19 consider themselves to be Aries. Today, the Sun is no longer within the constellation of Aries during much of that period. From March 11 to April 18, the Sun is actually in the constellation of Pisces!"
