Why is the Sun just entering the constellation of Pisces whereas it should actually be entering Aries?

Every constellation is entered by the Sun approximately one month after it should have been entered by it according to the commonly accepted zodiacal concept. This rule seems to apply to all recorded history (source: Stellarium)|||The "commonly accepted" zodiacal concept is NOT commonly accepted.



It is only "accepted" by astrologers, who find it convenient (for their horoscopes) to used fixed dates to identify the "houses" where the Sun is on a given date.



The dates used by western astrologers appear to coincide with the apparent positions of the Sun roughly 2000 years ago.



I do not know which "rule" you talk about. The dates ON AVERAGE would have been somewhat OK about 2000 years ago.



Here is how it was done:



There is roughly 12 months in the year (under lunar calendars, some years have 12 months, other years have 13 months), each month being - in the old days, around 29.5 days long on average. A month would begin either at New Moon (as in the Chinese calendar) or at the first sighting of the Crescent Moon (as in the Muslim calendar).



Thus the apparent position of the Sun against the background of stars, was associated with a group of stars for each month (and yes, there were 13 constellations, the now-forgotten one being Ophiuchus, the Serpent Bearer). Most of these constellations represented an animal (hence the root zoo- from the Greek word for animal) that the circle of the ecliptic became known as the zodiac (-diac is from another Greek word, for circle).



It is with the adoption of the Roman calendar (12 months based on the solar year) that the zodiac became officially divided in 12 sections (Ophiuchus was dropped). Because the Roman calendar's dates were not based on the Moon, it was much easier to use it with fixed dates.



Because the date for the Spring Equinox was March 21, the date "21" was picked as the astrological starting point. The actual constellations were replaced with "houses" which had the advantage of being of equal width (time-wise) - the constellations themselves were of various width, with some of them being much wider than one month (Virgo, for example).



So astrologers picked 21 March to 21 April as the dates when the Sun was in the house of Aries (for example) even though by that time, the position of the Equinox was very close to moving into Pisces.



Because of precession, the position where the equinox takes place is slowly moving around the ecliptic (one full circle in 25,800 years) so that very "soon" it will take place in Aquarius (sometime after the year 2085 which, in astronomical terms, is very "soon").



So that , if you wait long enough, the houses of the astrologers will be TWO constellations behind on reality.



It does not really matter, since astrology is not based on anything real.

@ bestonnet_00:

Some astrologers have long understood that they can make lots of money selling horoscope to gullible people and to newspapers that are read by gullible people. That shows that they are not really idiots.



Also, many astronomers used to be astrologers way back then (after all, they too needed to make money every once in a while). It is only in the 17th century (when Newton showed that the orbits of planets could be explained by gravity alone) that astronomy and astrology formally parted company for good.



The best astrologers (meaning = most "successful") are the ones who know how to work gullible people - they also know that their "predictions" are not important. Their role is to give their customers a dream that reality cannot give them. It is very similar to religion in that respect.



"Who should I marry"

"Hmm... I see your Jupiter is in quadrature with the solstice, so I suggest that you marry a Taurus."



It does not matter that a "Taurus" is someone born when the Sun is in Aries or in Pisces. What does matter is that if a person is told that their marriage will work because the spouse is a Taurus, then there is a (slightly) better chance that the marriage will actually work (self-fulfilling prophecy).|||Precession of the equinoces.

In the long and very long range, Sun's address as per any calender day remained almost constant. But instead, the Equator now cuts the Ecliptic about 22掳 or 27掳 back, depending on which year "the first point of Aries" was fixed. I am dealing in the Astronomy of days of yore (one %26amp; a half millennia ago) when this was done and do not confirm to the present day boundaries drawn by Eugene delporte almost a century ago, for the sake of accuracy (you may like to translate to the present day figures of today; but that doesn't diminish the Astronomy content of those days).

With the Ecliptic fixed, only the (Celestial) Equator that slides on it at the rate of about 1掳 in 72 years %26amp; their intersecting nodes slide on the Ecliptic. Once, Vernal Equinox (VE) used to be on 14, April (that is still reckoned as the traditional Tamil New Year wherever Tamils are), but now it is March 20/21. You may see Sun's address amongst the stars for these dates. In about 25800 years the VE will have traversed through March to December, to November, September and all the way back to April 14.

Right now it has entered Pisces for the VE (that was Sun's address corresponding to the traditional Astronomy then).|||The short answer is that astrologers are idiots, every last one of them.





The long answer has to do with precession which has shifted the constellations over the past thousands of years (while the idiot astrologers refuse to update to what is happening now).|||Here is why:

The first point of Aries have shifted to about27degrees.
