Chaturthi Shraddha is done for those deceased family members who died on Chaturthi Tithi, including both Shukla and Krishna Paksha Chaturthi.
Chaturthi Shraddha is also known as Chauth Shraddha.
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.
Chaturthi Shraddha is a special ritual performed on the fourth day, i.e., Chaturthi Tithi of the Pitru Paksha. According to Hindu scriptures, each Tithi has its own specific significance, and performing Shraddha on the same Tithi on which a forefather passed away is considered most auspicious. If a forefather departed on the Chaturthi Tithi, then performing Shraddha, Pinda Daan and Tarpan on this day is scripturally prescribed and highly meritorious.
If the exact Tithi of the forefather's demise is not known, then a Shraddha may be performed on the day of Sarva Pitru Amavasya following proper rituals. However, conducting the Shraddha on the correct Tithi yields greater spiritual benefits. Those who perform Chaturthi Shraddha are blessed by the Pitragana, i.e., ancestors with family welfare, peace, prosperity and abundance. Performing Shraddha on this day also aids in family lineage growth and resolve Pitru Dosha.
According to the descriptions found in sacred texts such as the Manusmriti, Yamasmriti, Grihya Sutras and Nirnaya Sindhu, performing Shraddha on the Chaturthi Tithi greatly pleases the ancestors. Their satisfaction brings joy, peace, wealth and progeny to the family. This Shraddha is considered highly favorable for progeny, well-being, health and longevity within the family.
