Thank you for your kind and early reply. My husband attained Shivalokaprapthi on Adi month, Krishna paksha, Saptami tithi at 10:06 PM. We belong to Yajur Vedam, Aabasthamba Sutram. 27th day Oonam Maasikam was performed on 6th Sept, its Sodakumbham was performed on 5th Sept. On both days my son did Hiranya Sraadham offering rice and plantain. On Sodakumbham day, we offered a brass water pot to the brahmin. On 8th, one more sodakumbham was performed offering rice plantain and brass water pot to one brahmin. On 9th, 2nd tithi maasikam has to be performed offering rice and plantain. Sastrigal told 45th day Sodakumbham maasikam to be performed on 20th and 21st September. My 2nd son's star is Moolam.On 45thday masikam two brahmins have to be fed with samaraadanai samayal as there is no homam as per sastrigal. Sastrigal tells when my first son returns from abroad he has to observe 3 days thindal, and perform chaundikaranam. At present homa is not performed because of the coronavirus situation, as it is difficult to get brahmins for the homam. Kindly guide us regarding the procedures to be undertaken when my elder son comes.
