Dear Sriman Ravi,

Thanks a lot for your inputs, i am requesting members who are well versed in
to work on this script. Since time zones differ and hence the time of
sunrise/sunset in USA are different from India, we have to adjust the input
timings to each specific geographic location. GMT for London, CST for Ames
EST for New York,et al.

I am requesting elders in this forum to post a small write up on panchangam
and how calculations are to be done. This will particularly help bhaktas who
wish to learn more about panchangam from the ABCs.

On a connecting matter, I request  members to read the book on "Ancient
Indian Mathematics" by Dr.Bhanumurthy. I am not aware of it's availablity in
USA, but there should be lots of bookstalls in India which should have this

There is also a small write up on the mathematical aspects of the
panchagams. This book is a must read for interested bhaktas.
There is more to the panchagam, apart from being a calendar/almanac. It
represents the highest repository of highly accurate astonomical data and
deductions. There is even calculation for the parsec  which is equal to 2.5
light years and is now taken as an astronomical standard. The calculations
for parsec where there in the "Ganita Saashtrams" of our purvAcharyals,
centuries back.

It is interesting to consider a small note from A. Seidenberg :

In his monumental work, The origin of mathematics, Archive for History of
Exact Sciences. vol. 18, 301-342, A. Seidenberg remarks:

"By examining the evidence in the *Shatapatha Brahmana*, we now know that
Indian geometry predates Greek geometry by centuries. For example, the earth
was represented by a circular altar and the heavens were represented by a
square altar and the ritual consisted of converting the circle into a square
of an identical area. There we see the beginnings of geometry!

Two aspects of the 'Pythagoras' theorem are described in the Vedic
literature. One aspect is purely algebraic that presents numbers a,b,c for
which the sum of the squares of the first two equals the square of the
third. The second is the geometric, according to which the sum of the areas
of two square areas of different size is equal to another square. The
Babylonians knew the algebraic aspect of this theorem as early as 1700 BCE,
but they did not seem to know the geometric aspect. The Shatapatha Brahmana,
which precedes the age of Pythagoras, knows both aspects. Therefore, the
Indians could not have learnt it from the Old-Babylonians or the Greeks, who
claim to have rediscovered the result only with Pythagoras. *India is thus
the cradle of the knowledge of geometry and mathematics*."
