Tithi-vicara
Determination of Tithi for Fasts, Parana, and Pitri Rites
शुक्ले पूर्वाह्णिके ग्राह्ये कृष्णे ग्राह्येऽपराह्णिके । अयनं दिनभागाढ्यं संक्रमः षोडशः पलः ॥ ३४ ॥
śukle pūrvāhṇike grāhye kṛṣṇe grāhye'parāhṇike | ayanaṃ dinabhāgāḍhyaṃ saṃkramaḥ ṣoḍaśaḥ palaḥ || 34 ||
শুক্লপক্ষে পূর্বাহ্নে গ্রহণীয়, আর কৃষ্ণপক্ষে অপরাহ্নে গ্রহণীয়। অয়নে দিনের অতিরিক্ত এক অংশ গণ্য হয়, এবং সংক্রম (সূর্য-প্রবেশ) ষোলো পল পরিমিত॥৩৪॥

It emphasizes dharmic precision: aligning rites with correct lunar fortnight and day-part is presented as a way to harmonize human action with cosmic order (kāla), strengthening the sanctity and efficacy of observances.
While technical, it supports bhakti-practice by guiding devotees to perform pūjā, vrata, and dāna at traditionally appropriate times—showing that devotion in the Purāṇic tradition is expressed through disciplined, time-conscious worship.
Vedāṅga Jyotiṣa (astral/timekeeping) is highlighted: selecting pūrvāhna vs aparāhna based on pakṣa, and defining calendrical markers like ayana and saṅkrama with specific time-units (pala).
