My son will complete one year in this Karthigai month. He was born on 27-Nov-2012 in Barani star on the day of Barani Deepam/Karthigai Deepam. In this year, the Barani star comes twice in the month of Karthigai. The first occurrence happens on 17-Nov (Barani Deepam/Karthigai Deepam) and second one in Dec (14th). Should I do the ayush homam of my son on the first occurrence of the star or the second one ? We follow drik kanitha panchangam.
