Dvādaśī-vrata: Month-by-month Viṣṇu Worship and the Year-End Udyāpana
पूर्णँ संवत्सरं कृत्वा कुर्यादुद्यापनं व्रती । मार्गशीर्षासिते पक्षे द्वादश्यां च मुनीश्वर ॥ ८८ ॥
pūrṇaṃ saṃvatsaraṃ kṛtvā kuryādudyāpanaṃ vratī | mārgaśīrṣāsite pakṣe dvādaśyāṃ ca munīśvara || 88 ||
Tras completar un año entero, el observante del voto debe realizar el rito de conclusión (udyāpana). Oh excelso entre los sabios, hágase esto en el duodécimo día lunar (Dvādāśī) de la quincena oscura del mes de Mārgaśīrṣa.

It emphasizes that a vow is spiritually complete only when its udyāpana (formal concluding rite) is performed after the full intended duration, marking disciplined dharma and proper closure of the sādhana.
By prescribing a fixed sacred time (Dvādāśī) for the vow’s conclusion, it aligns devotional practice with Vaishnava observances where Dvādāśī is especially auspicious for completing Vishnu-centered vratas.
Kalpa and Jyotiṣa-style ritual timing: selecting the correct lunar month (Mārgaśīrṣa), fortnight (kṛṣṇa pakṣa), and tithi (Dvādāśī) for udyāpana.
