Vedic astrology has been used for over a millennium for predicting the future of various individuals, groups, countries and even buildings. The predictions depend on the exact time and location of an individual’s or country’s birth or creation. Many astrologers have precisely predicted the events of a country like America since its time or inception and certainly the location where it was created – Independence Hall, Pennsylvania, Philadelphia. By knowing the actual location and time, astrologers can create and predict the entire life of a person. However, as the centuries passed, the methods of creating horoscopes, birth charts or Kundlis varied according to the creativity of the astrologers. In India, there is marked difference in the methods by which the astrologers derive birth charts in the southern and in the northern part of India. The main difference in the birth chart South Indian style is the direction in which the houses of the horoscopes are drawn.
Every birth chart shows the divisions of the houses with distribution in degrees for each of these divisions. The first column starts with the zero degree sign of Aries and continues allotting 30 degrees for each sign in clockwise direction for a total of 12 houses in the horoscope. In the birth chart South Indian style, the astrology name for each sign is marked in blue and red is used to denote the allocation of degrees for each house. Our Rashi or Moon sign will be marked clearly as it is very important in Vedic Astrology.
The Jadakam or Jadagam as the birth chart South Indian style is called may hold the western name of the sign along with the Vedic Sanskrit name of the sign and the house number along with the total number of degrees it holds. In each house, there is another calculation of the Nakshatram or star which has a value of 13 degrees 20 minutes. Since there will be 2 ¼ stars in each house, the total for 12 houses is 108 quarters which constitutes the placement of all the 27 stars required for the South Indian horoscope.
In addition to the direction of the horoscope, the names of the months or Rashi are also different in the birth chart South Indian style. Example of month names in South Indian style are Meenam, Mesham (or Medam), Rishabam, Mithunam, Karkadakam or Katakam, Kumbham, etc. the Rashi names are such as Ayilyam, Pooram, Avittam, Purattathi, Pusam (pooyam), Revathi, Uthirattathi, Rohini, Thiruvathirai, etc.
