January 12 cusp astrology
Ptolemy quotes from Hipparchus' now lost work entitled "On the Displacement of the Solstitial and Equinoctial Points" in the seventh book of his 2nd century astronomical text, Almagest , where he describes the phenomenon of precession and estimates its value.

The principle of the vernal point acting as the first degree of the zodiac for Greek astronomers is also described in the 1st century BC astronomical text of Geminus of Rhodes. Geminus explains that Greek astronomers of his era associate the first degrees of the zodiac signs with the two solstices and the two equinoxes, in contrast to the older Chaldean Babylonian system, which placed these points within the zodiac signs. Ptolemy also demonstrates that the principle of the tropical zodiac was well known to his predecessors within his astrological text, the Tetrabiblos , where he explains why it would be an error to associate the regularly spaced signs of the seasonally aligned zodiac with the irregular boundaries of the visible constellations:.
These events can be useful, for example, to estimate the cross-sectional dimensions of a minor planet , or check a star for a close companion. The Sun's placement upon the vernal equinox, which occurs annually around 21 March, defines the starting point for measurement, the first degree of which is historically known as the " first point of Aries ". Zodiac signs have never been used to determine the boundaries of astronomical constellations that lie in the vicinity of the zodiac, which are, and always have been, irregular in their size and shape.
The use of the zodiac as a means to determine astronomical measurement remained the main method for defining celestial positions by Western astronomers until the Renaissance, at which time preference moved to the equatorial coordinate system , which measures astronomical positions by right ascension and declination rather than the ecliptic-based definitions of celestial longitude and celestial latitude. The word "zodiac" is also used in reference to the zodiacal cloud of dust grains that move among the planets, and the zodiacal light that originates from their scattering of sunlight.

You set a high standard for yourself, but unlike other Capricorns, you also apply these standards to others. You tell yourself that if I am willing to set a high standard for myself, then everybody has to also live up to that standard.
The interesting thing about people with this personality trait is that in many cases, their aggressiveness, persistence and determination are rewarded by heartbreak. Your old definitions no longer hold true. The reason for this is because despite your exterior, you are a very soft-hearted person. You have an emotional core.
If you are able to speak to, and make peace with this emotional side, you would be able to become a happier person overall. People born on January 12 th are unstoppable by nature. You will never rest until you achieve your goal. For example, if the front door is blocked, you will try the side door.
If the side door is closed off, you will try the window. If the window is blocked, you will break a hole through the roof.
If the roof is sealed off, you will dig a tunnel underneath. Best of all, you have this tremendous amount of focus while projecting a cool, calm and collected exterior. You are a very persistent person and this is what makes you unstoppable. This also makes you very miserable. You have to remember that there are certain situations and relationships in this world that you have no business hanging on to. While you can be forgiven for stepping into them because you did not know any better, you cannot be forgiven for hanging on to them.
Know the difference. Unfortunately, there are certain situations where you only end up losing.
This might seem like a good thing, but it also reveals a total lack of emphasis on things that cannot be seen and emotions that cannot be measured. On the other hand, given your tendency to be stubborn, it is no surprise that your persistence can easily degenerate into personal oppression or addiction. You have to understand that in some cases, regardless of how much effort you put in, a lost cause will remain a lost cause.
Yet nevertheless, at the same time, when meeting other people from other walks of life with a strong mind and keen insight into how the world works, sparks inevitably fly. These friendly and offbeat people are superb at decoding the inner workings of society and pointing out its flaws with a big grin. However, people born on 12th January especially like their relationships to unfold along a steady path of meeting, dating, getting closer and eventually, further down the line, moving in together, doing some family and career planning, and so on.

This kind of roadmapping of life goes as much against the grain of Aquarius as can be, and as such, the flighty nature of the Aquarius person is likely to leave the 12th January zodiac soul high, dry and heartbroken.
