The difference between the Rasi Charts
of Indian System comprising of Nakshatras (starts with Ashwini Star) and the
Western System based on Seasonal set up is noted as Ayanamsa.
The
Astrological System adopted by Indians is called the " Nirayana (or)
Sidereal " System, While Western Astro-analysis is called " Sayana
(or) Tropical " system.
Sayana means inclusive of Ayanamsa
while Nirayana means exclusive of Ayanamsa.
The date of Coincidence of the Tropical
& Sidereal Zodiacs was found to be 285 A.D on 22-March at 21H:27M(IST) as
Zero Ayanamsa by Great Astro-Mathematician Lahiri.[According to Calender
Reforms Committee].
Various Scholars have different
opinions on Ayanamsa Date:
- Cheiro - 388 B.C
- D. Davidson - 317 B.C
- G Massay - 255 B.C
- Therens - 125 B.C
- P Covneez - 0
- Cyril Fagan - 221 A.D
- Lahiri - 285 A.D
- Krishna Murthy - 297 A.D
- P.S Ray - 319 A.D
- B.V Raman - 397 A.D
- Sepharial - 498 A.D
- Madhura Krishna Murthy Sastry - 411 A.D
- Swamy Kannu Pillai - 532 A.D
Degrees in Sayana system - Ayanamsa =
Degrees in Nirayana system. This formula is useful to calculate the sphutas of
Graha, Bhava and Lagnas.
Today Ayanamsa
[Chitrapaksha/ Lahiri] = 24˚:3': 48" {24-Oct-2014}
Good information to astrology students.

ReplyDeleteProbable derivation of sidereal longitude of pushya as given by Surya Siddhanta etc
ReplyDeleteAssumption
ReplyDeletePita maha Siddhanta chitra=183:0
Why
Accepted epoch=80AD
As on 80AD, tropical spica=177:0
Also, tripical longitude separation between eta piscium and spica=177:0
Complementary arc Distance=360-177=183:0
Alignment with Pitamaha Siddhanta chitra of 183:0
Geometric chitra=180:0(aligned with Surya Siddhanta chitra of 180:0)
Midpoint=181:30
Tropical longitude separation between delta cancri and Arcturus (yoga tara of Swati which is end of chitra also)=75:30
So, sidereal pushya=181:30 of calculated chitra -75:30 of tropical separation between delta cancri and chitra end of Arcturus=106:0
Alignment with 106:0 of pushya of both Surya Siddhanta and Pitamaha Siddhanta
By fixing delta cancri at 106:0 sidereal,we can derive pushya Paksa ayanamsa
Final summary regarding the longitude of Siddhantic pushya in Vedic astrology
