One should perform the sraddha ceremony on the Makara-sankranti [the day when the sun begins to move north] or on the Karkata-sankranti [the day when the sun begins to move south]. One should also perform this ceremony on the Mesa-sankranti day and the Tula-sankranti day, in the yoga named Vyatipata, on that day in which three lunar tithis are conjoined, during an eclipse of either the moon or the sun, on the twelfth lunar day, and in the Sravana-naksatra. One should perform this ceremony on the Aksaya-trtiya day, on the ninth lunar day of the bright fortnight of the month of Kartika, on the four astakas in the winter season and cool season, on the seventh lunar day of the bright fortnight of the month of Magha, during the conjunction of Magha-naksatra and the full-moon day, and on the days when the moon is completely full, or not quite completely full, when these days are conjoined with the naksatras from which the names of certain months are derived. One should also perform the sraddha ceremony on the twelfth lunar day when it is in conjunction with any of the naksatras named Anuradha, Sravana, Uttara-phalguni, Uttarasadha or Uttara-bhadrapada. Again, one should perform this ceremony when the eleventh lunar day is in conjunction with either Uttara-phalguni, Uttarasadha or Uttara-bhadrapada. Finally, one should perform this ceremony on days conjoined with one’s own birth star [janma-naksatra] or with Sravana-naksatra.
