[Advaita-l] Sringeri Panchanga

[Sundaram Venkatraman]

Dear Sarmaji,

It is in the conversion of Sayana to Nirayana that there emerges a chink in your scientific observation argument. The star that pointed to Mesha 0 degrees, it seems, has vanished. So most ayanamsas are derived on the basis of an arbitrarily decided date on which sages like Parashara or Varamihira are supposed to have written their astrology classics. On that date it is assumed that the Sayana and Nirayana zodiacs were in total alignment. It is scientifically determined that every year Mesha 0 deg of Sayana zodiac precedes by 50 secs. So from that arbitrarily decided date, total degree of precession of equinoxes till the current year (Durmukhi for us) or ayanamsa is calculated and the same is deducted from the Sayana degrees of various planets to arrive at their Nirayana degrees. And there are more ayanamsas than can be counted on the fingers of both hands. The most popular among the ayanamsas is the Lahiri ayanamsa which is adopted by the calendar reforms committee of Govt of India. So as you can see there is absolutely nothing that is very scientific about the determination of Nirayana zodiac. All the science that is involved in the determination of the Sayana zodiac which is based on actual observations is lost in the translation to the Nirayana zodiac. Since the drikganita Panchangs are based on Nirayana zodiac they are as reliable as the ayanamsa on which they are based. Kanchi mutt's panchang is based on Lahiri ayanamsa.

Venkat
