My younger brother Narayanan attained the heavenly abode (passed away) before 6:00 AM on 17.7.23. The commencement of the Tamil month of Aadi happened only that afternoon. The entire day was Sarva Amavasyai. For the subsequent years, should his Shraddha (annual ancestral rituals) be performed on Aani Amavasyai or Aadi Amavasyai? For the past 3 years, it has been performed on Aani Amavasyai. Currently, someone in the family says it must be done only on Aadi Amavasyai. We consulted two priests and performed it in the month of Aani. I am concerned that we may have done something wrong. I kindly pray that you provide the correct solution for this.
