Bharani Shraddha is done during Pitru Paksha when Bharani Nakshatra prevails during Aparahna Kala. Bharani Nakshatra prevails either on Chaturthi Tithi or Panchami Tithi during Mahalaya Paksha.
Bharani Shraddha is known as Chauth Bharani or Bharani Panchami when Bharani Nakshatra prevails during Aparahna on Chaturthi Tithi or on Panchami Tithi respectively. (In some years Bharani Nakshatra might also prevail on Tritiya Tithi. Hence Bharani Shraddha is not linked to any Tithi.)
Bharani Shraddha is known as Maha Bharani Shraddha. Nakshatra Bharani is significant during Pitru Paksha because it is ruled by Yama, the God of the Death.
The benefits of doing Bharani Shraddha are equivalent to those of Gaya Shraddha. Usually Bharani Nakshatra Shraddha is done once after the death of the person but according to Dharmasindhu it can also be done every year.
Pitru Paksha Shraddhas are Parvan Shraddhas (पार्वण श्राद्ध) and auspicious time to perform them is either Kutup Muhurat and Rohina etc. Muhurat after that till Aparahna Kala gets over. Tarpan (तर्पण) is done at the end of the Shraddha.
