The Mahabharata of Krishna-Dwaipayana Vyasa…
“ By performing the Sraddha on the twelfth day one always beholds, if one desires, diverse kinds of beautiful articles made of silver and gold. By performing the Sraddha on the thirteenth day one attains to eminence over one's kinsmen. Without doubt, all the young men in the family of him who performs the Sraddha on the fourteenth day meet with death. Such a man becomes entangled in war. By performing the Sraddha on the day of the new moon, one obtains the fruition of every wish. ”
