मृताहर्यो न जानाति मानवो यदि वा क्वचित् । तेन कार्यममावास्यां श्राद्धं माघेऽथ मार्गके
mṛtāharyo na jānāti mānavo yadi vā kvacit | tena kāryamamāvāsyāṃ śrāddhaṃ māghe'tha mārgake
Jika seseorang tidak mengetahui (atau ragu-ragu) hari kematian yang tepat, maka śrāddha hendaklah dilakukan pada hari amāvāsyā (bulan mati), pada bulan Māgha, atau jika tidak, pada bulan Mārgaśīrṣa.

The rule is transmitted within the Prabhāsakṣetra-māhātmya, linking correct Pitṛ observance with the sacred authority of Prabhāsa traditions.
