Hand-written charts?

[Guest guest]

Dear Prabhu's

 

Please accept my humble obeisances. All glories to Srila Prabhupada.

 

I was wondering how astrologers used to calculate charts in Vedic times

without the use of computers like we are used to in our modern time. Are

there any books which describe how to calculate a chart by hand? And are

there still astrologers these days in India who calculate whithout the use

of computer?

 

Your servant,
