Entre los devotos versados en los śāstra, esto es célebre como “Bhūtaviddhā”. Pero, en caso de un kṣaya extremo (gran pérdida del tithi), debe observarse al día siguiente, y no en la tarde del día nominal.

FAQs
It emphasizes śāstra-based precision in dharma: spiritual merit depends not only on devotion but also on correctly determining the observance time (kāla) when calendrical anomalies like tithi-kṣaya occur.
Bhakti is protected from error by following scriptural timing rules; the verse implies that sincere devotion should be aligned with correct vrata-kāla, especially when the tithi is ‘lost’ and the observance must shift to the next day.
Jyotiṣa/Vedāṅga calendrics (pañcāṅga logic): recognizing tithi-kṣaya and applying the rule that in extreme kṣaya cases the observance is on the next day, not in the aparāhṇa of the nominal day.
