Contemporary use of the coordinate system is presented with the choice of interpreting the system either as sidereal , with the signs fixed to the stellar background , or as tropical , with the signs fixed to the point vector of the Sun at the March equinox. Western astrology takes the tropical approach, whereas Hindu astrology takes the sidereal one.
This results in the originally unified zodiacal coordinate system drifting apart gradually, with a clockwise westward precession of 1. For the tropical zodiac used in Western astronomy and astrology, this means that the tropical sign of Aries currently lies somewhere within the constellation Pisces " Age of Pisces ". The sidereal coordinate system takes into account the ayanamsa , ayan meaning transit or movement , and amsa meaning small part , i. It is unclear when Indians became aware of the precession of the equinoxes, but Bhaskara 2 's 12th-century treatise Siddhanta Shiromani gives equations for measurement of precession of equinoxes, and says his equations are based on some lost equations of Suryasiddhanta plus the equation of Munjaala.
The discovery of precession is attributed to Hipparchus around BC. 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.

If chivalry is just a nervous habit, you could do much worse. And you're so over that whole school-yard bully dynamic, anyway. Get beyond appearances today and show them that real wolves and real sheep have transcended their storybook roles. People have good and bad sides, and right now being decisive, loyal and, yes, polite will resolve a lot more problems than those behaviors create. In the end, that resolution is what brings real security. It doesn't matter whether you're under pressure, stretched tight or at loose ends. You could be all revved up or as subdued as a whisper.
Today will find you vague and moody. It'll be harder than usual to fake sincerity if you're not feeling it. Flippant remarks might cut deeper than you intended. Try harder to stay in focus so that you can read the situation better. It's OK to let people know your current limitations, but you have to be kind about it. You'd expect the same courtesy. At the moment, your heart and mind are quietly untroubled. Today you're as peaceful as a dove and helpful as a child, which means you're content to let others run the show. You have no problem taking direction from someone else, as long as their heart is in the right place.
You're demonstrating the power of acquiescence now. This doesn't mean that you've given up control to someone else, though. It's just that passive control can be so much easier. Not to mention more effective! Something's off.

Maybe your mood and energy aren't right. You feel entitled to many things, but you don't quite know what they are. You could be feeling needy or grabby. On the other hand, you might have enough self-control to restrain yourself until you figure out what you're lacking. What matters more is how you fulfill those or soothe those needs. One thing is certain: Good or bad, this will be a brief, surprising period. You could learn a lot about yourself and the way you operate. Be forewarned: The immaculate condition of your life is about to change. The waters are muddied by messy emotions today.
As much as you might prefer life to be neat, clean and efficient at all times, you have to accept the fact that you occasionally need other people. Whatever's going on, consider this a warm welcome back into human society. This is what being alive is all about, so enjoy it. Be glad there's affection in your life.
That's far more than some can say. You've been trying your hardest. You've been wearing the biggest smile you've got and speaking in your sweetest voice. And yet, you just can't seem to win them over. All this toxic niceness is backfiring. It's time to do something decisive to save the situation, or at least yourself.
Today, figure out a way to shake them awake by other means. And don't neglect the benefits of stating your case or your opinion plainly. You tend to avoid being direct with people, but sometimes it's the only way to get through to them.
Your weekly horoscope: October 8 - October 13, 12222
You've been keeping to yourself, haven't you? When the phone rings, you let your voicemail answer. When a friend sends an e-mail, you file it away for later response. And that's okay. Seclusion suits you well right now. Your focus and energy have turned inward. You're taking sublime inventory of your true, inner self. It's best to keep your own counsel today. That way, you can tighten your focus and establish a solid plan for the moment you'll spring into action. And when that happens, well -- watch out, world! You seem careless and quirky, fashionably sloppy yet daring to be different.
It's all an act, obviously a very good one, but an act just the same. Deep down, you're seething with conventional anxieties. Welcome to the human race. Of course, you don't have to dwell on this stuff all the time. Just be yourself today as kind of a check-in. Let real friends offer real help. They actually like you even if you're all living with one foot in the land of illusion. And that's one less reason to complain. Respect what others call holy or authentic, even if your inner voice tells you they're trying to scam you or just deluding themselves.
But along with giving them your respect, it wouldn't hurt to look beyond or behind what they say. Maybe you'll get a better idea about what they're thinking and what unseen forces are at work here. Keep these investigations within the realm of peaceful curiosity, because you're really not trying to make trouble. You can learn a lot about your world today, and maybe then you'll be better qualified to judge, or even see that judgment is meaningless.
Today is a good time to connect with your own watery energy. Let it flow subtly and beautifully by meditating on the movement and quality of water itself -- that free-flowing thing that meanders wherever it can. That's how your thoughts should work. Don't curtail your imagination or impose any expectations of practicality on yourself, especially if you're developing ideas for a project. Let your mind flow. Take notes on where it leads you.
Most of all, don't be lured by loud, shiny novelties. You don't need them. The best stuff comes unannounced. Be ready to respond to anything.
Maybe they're saying it's none of your business, but how can any of you be sure about that? Your words will be liquid today, and your actions will be fluid. Your position will be bendable, too. Either you do a lot of yoga, or you've got relaxation down to a science. Some people may call you spineless for all this, but that's only because they're so rigid.

Keep your motives pure. That way, other people will know they can trust you. Does this really cost you so much? Even if today's reality doesn't line up with your favored fantasies, at least you'll know you're not forcing it. They don't have to tell you what good taste is.
