I did a simple trick, as you know Indian horoscope works on lunar system. I added randomly 15 October 1959 in one horoscope tool, which gave me
Lunar Month as Ashwini and
tithi as Shukla Chaturdashi, then I found I am close to tenth day of the bright half of the Hindu month of Ashwini.
On reducing 4 day I found the calculation of Dussehra.
