The Chinese calendar does not start on Jan. So if you were born in January or February, you must check where the date fell in your birth year, as your sign and element might be of the prior Western calendar year. Each of the elements is dominant for two years, and with five elements the cycle repeats every 10 years. This is referred to as the 10 stems or 10 heavenly stems. Knowing your birth element can help you create the best feng shui for your home or office. It can guide the decor colors , items, and areas you should emphasize and minimize.
For example, if you were born in a fire element year, you should use shades of red and yellow fire colors while minimizing white, gray, green, and brown metal and wood colors. You also should emphasize the fireplace and decorate with candles while avoiding metal decor. The 12 Chinese zodiac animal signs change each lunar year.
Your birth zodiac animal is said to guide your personality traits and influence your compatibility with certain people. 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.
Make Sure You Have the Right Zodiac Sign
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.
