Tithi-vicara
Determination of Tithi for Fasts, Parana, and Pitri Rites
पारणे मरणे नॄणां तिथिस्तात्कालिकी स्मृता । पित्र्येऽस्तमनवेलायां स्पर्शे पूर्णा निगद्यते ॥ १५ ॥
pāraṇe maraṇe nṝṇāṃ tithistātkālikī smṛtā | pitrye'stamanavelāyāṃ sparśe pūrṇā nigadyate || 15 ||
在破斋(pāraṇa)与人命终之时,应取当下正在运行的月日(tithi)。但于祖先祭仪(pitṛ-karman)中,若该tithi触及日落前后之时段,即宣称为“圆满”,可全然适用。

Secondary Rasa: bhakti
It preserves dharmic precision in time-keeping: different sacred acts require different tithi rules, ensuring that vrata observance and pitṛ-tarpaṇa/śrāddha are performed in the correct temporal window.
It supports bhakti through disciplined observance—proper pāraṇa timing protects the integrity of a Vishnu-centered vrata, while correct pitṛ rites uphold gratitude and dharma, both considered supportive to spiritual progress.
Vedāṅga Jyotiṣa (Vedic calendrics/astronomy): it distinguishes “moment-prevailing tithi” for pāraṇa and death from the “sunset-contact tithi counted as complete” rule used for pitṛ rites.
