The main difference between western astrology and vedic astrology is that within one year the zodiac constellations will be split into two distinct systems. Western astrology is based upon a tropical (or fixed) zodiac system. That determines the year as the beginning of Aries on the 21st of March and thus the dates of each of the 12 zodiac signs.
In comparison, Vedic astrology is based on a “corrective systems known as ayanamsa. Account for the precession of equinoxes sidereal zodiac scheme. In Vedic astrology Aries is also the first indicator of zodiac. It starts on 14 April because of some corrective calculations (and is known as Mesha Rashi).
However, as regards fixed stars, the vernal equinox is moving westward at a rate of around 50.26 seconds of an arc per year. It is also called an equinox or ayanamsa precession.
This is because the Earth axis still turns every about 26000 years and completes one rotation. Vedic astrology also takes this small change in earthly location into account, which shifts from the 0-degree vernal equinox point of the sidereal zodiac west to about 25 degrees. Ved shastra is based on the year of Sidereal instead of the tropic year. It is the time the planet takes for the Sun to transform with regard to the star Chitra. This is seemingly twenty minutes longer than the tropical year.
As a result, the Aries of Western Astrology continues to drift at a rate of one degree every 72 years farther from the Aries point of Vedic astrology. In the past 2000 years, this gap has now risen to nearly 24 degrees. About 285 AD captured the last aircraft of the Aries of West Astrology and Vedic Astrology. Sayana is the astrology system that uses the zodiac. Which is called Nirayana and it uses moving zodiacs.
The world is expanding and nothing is still after the planetary motions alter. Vedic astrology is more logical and accurate. Signs and planets have similar interpretations and symbolic significations in both systems in general. But Vedic Astrology is much more reliable with more accurate and detailed calculations.
Vedic astrology seems simple, compared with the western system, since it is based on more precise astronomical concepts. The planets moving in the sky according to the Nirayana system must be taken into consideration. Not only the natural map, but dasas, the different planets’ phases that pass through various signs and their effect in real time are measured by Vedic astrologers. In addition, Vedic Astrology is moon sign over Sun sign.
In around a month, the Sun changes its sign when the Moon changes it in 2,25 days. So moon-based forecasts are narrower and more precise as our moods and circumstances sometimes change. Secondly, the moon represents mind and emotions, our temperament, which contributes to more important forecasts and interpretation through interpreting the moon’s placement. Vedic Astrology is also more accurate than Western astrology by more precise and details-oriented prediction techniques and methods.
