ayanamsha calculation

[Guest guest]

Dear Donna -- Thanks for clarification: I understand now that you

meant you reset the ayanamsha for each chart's specific date. For

absolute precision this is probably the best thing to do, but as I

say, opinions are definitely divided about the question of

fluctuating acceleration of the rate of precession, as reflected in

the excel ayanamsha calculator, so I personally am happy with the

approximate mean value proposed in the lessons (Lahiri -1°01') (also

happens to be same as excel calc for my birthday...).
