Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
सप्तोर्द्धनावशेषौ तौ विज्ञेयौ मासवर्षपौ । स्नेहस्य भगणाभ्यस्तो दिनराशिः कुवासरैः ॥ ८१ ॥
saptorddhanāvaśeṣau tau vijñeyau māsavarṣapau | snehasya bhagaṇābhyasto dinarāśiḥ kuvāsaraiḥ || 81 ||
Those two remainders, leaving seven and a half over, are to be understood as the month and the year. And the total number of days—obtained by applying the cycles (bhagaṇa) to the given quantity—should be expressed in terms of the resulting weekdays (vāras).
Narada (teaching technical computation in the Vedanga/astronomical mode within the Moksha-Dharma section)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It frames sacred time (māsa, varṣa, and vāra) as something knowable through precise reckoning, supporting dharmic practice by aligning vows, rites, and observances with correctly computed calendrical time.
Indirectly: by emphasizing correct time computation, it underpins bhakti-based vratas and pūjā schedules—devotion becomes steadier and more disciplined when performed at properly determined sacred times.
Jyotiṣa Vedāṅga: using bhagaṇa (astronomical cycles) and remainders to derive month/year measures and then converting the computed day-total into weekday (vāra) reckoning.
