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).
