Magha Shraddha is done during Pitru Paksha when Magha Nakshatra prevails during Aparahna Kala. If Magha Nakshatra prevails partially during Aparahna Kala on two days then the day when it prevails for longer duration it considered.
If both Magha Nakshatra and Trayodashi Tithi prevail during Aparahna on the same day then it is known as Magha Trayodashi Shraddha. Nakshatra Magha is significant during Pitru Paksha because it is ruled by Pitrs(पितृ), the spirits of the departed ancestors.
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.
As per Hindu scriptures, there is a profound connection between the ancestors and the Magha Nakshatra. Texts such as the Garbha Upanishad, Garuda Purana and Nirnaya Sindhu describe Magha Nakshatra as a representative of the Pitris. Therefore, performing Shraddha on a date that coincides with Magha Nakshatra is considered especially auspicious and highly pleasing to the ancestors.
According to the description found in Hemadri, all sons, whether residing together or at different places must perform the Magha Shraddha separately. In the scriptures, Magha Shraddha is regarded as highly meritorious and conducive to growth and prosperity.
Magha Shraddha is particularly performed for those ancestors whose exact date of death is not known or for whom Shraddha could not be performed during the year due to some reason. According to various scriptures, if the appropriate Tithi for Shraddha is not remembered, then performing Shraddha, Tarpan and Pinda Daan on a date associated with Magha Nakshatra is highly beneficial. Especially during Pitru Paksha, if the Trayodashi or Chaturdashi Tithi coincides with Magha Nakshatra, then performing Shraddha on that day satisfies the ancestors for thousands of years.
As stated in the Garuda Purana, Shraddha performed during Magha Nakshatra leads the ancestors to attain Vishnu Loka and they bless their descendants with good health, long life, wealth, progeny and peace. The Tarpana, Pinda Daan and Brahmin Bhoj done on this day yield manifold spiritual benefits. The Dharmasindhu also notes that performing Shraddha with Madhu (honey) and Payas, i.e., sweet rice pudding or Kheer on this day is especially fruitful.
If a family is suffering from issues such as untimely deaths, mental distress, obstacles in marriage, infertility or threats to family lineage, then performing Magha Shraddha with devotion is considered extremely beneficial. Offering meals to Brahmins, performing Tila-Jala Tarpan, donating clothes and lighting lamps on this day is believed to remove Pitru Dosha and bring peace and prosperity to the household.
