I just caught a glimpse of the First National Conference on Panchanga Ganitam being held 24 -26 December 2010 in Tirumala, India. Apparently it is being webcast live. I have enquired as to when Patrizia Norelli-Bachelet will be scheduled to read her paper [Link HERE to read full text], and will announce it here if I find out so that others who are interested may watch.
A Panchanga is a Hindu calendar [see Wikipedia]. There are numerous Panchangas that people follow in India and Patrizia Norelli-Bachelet is speaking to the effect that the real Vedic Year that should be adopted as the Hindu calendar is the Tropical Zodiac, based as it is on the four cardinal pillars of the equinoxes and solstices. [See Unity and the Hindu Samaj]. Ganitam, I believe means mathematics.*
It seems that much of the presentations won't be in English. Maybe they will translate the transcripts at some point.
