Dvādaśīद्वादशी(Dwadashi)
The twelfth tithi; devatā Viṣṇu (Hari), Bhadrā-class, classical register of fast-breaking and devotional register.
Dvādaśī
Dvādaśī (द्वादशी, also written Dwadashi) is the twelfth of the thirty tithis, occurring in both Śukla-pakṣa and Kṛṣṇa-pakṣa. Its presiding devatā is Viṣṇu — addressed in the tithi context specifically under the name Hari, the aspect of Viṣṇu as remover of suffering and as the deity to whom the morning invocation turns. In the five-class auspiciousness scheme of the Muhūrta Cintāmaṇi, Dvādaśī belongs to the Bhadrā class (tithis 2, 7, 12) — the wholesome, generally favourable register. The tithi's most direct classical function is as the pāraṇa day on which the Ekādaśī vrata is broken.
Classical grounding
Muhūrta Cintāmaṇi and the Nirṇaya Sindhu identify Viṣṇu as Dvādaśī's devatā, addressing the deity as Hari in this tithi context. The Padma Purāṇa and Viṣṇu Purāṇa provide extensive treatment of the Dvādaśī pāraṇa — the specific window within Dvādaśī during which the Ekādaśī fast is classically broken, with detailed rules about timing relative to sunrise and to the tithi's end. The Dvādaśī register extends beyond the pāraṇa function: Govinda Dvādaśī (Phālguna-Śukla) and Guruvāyūr Ekādaśī-Dvādaśī (Vṛścika-month regional observances) are specific annual observances tied to Viṣṇu-Hari's devatā register.
Significations
What Dvādaśī classically governs:
- Pāraṇa — the classical breaking of the fortnightly Ekādaśī fast, performed on Dvādaśī within a specific window determined by sunrise and tithi-end timing
- Viṣṇu-oriented devotional observance in continuation of the Ekādaśī register
- Bhīṣma Dvādaśī (Māgha-Śukla-Dvādaśī), associated with Bhīṣma Piṭāmaha's classical uttarāyaṇa observance
- Bhadrā-class general auspicious undertakings — travel, formal arrangements, ceremonial openings
- Recitation of Viṣṇu Sahasranāma and related Vaiṣṇava stotras
- Charity in the Vaiṣṇava register, often linked to the prior day's vrata fulfilment
Pakṣa-level reading
In Śukla-pakṣa, Dvādaśī carries the waxing register and the pāraṇa function for the Śukla-Ekādaśī vrata that precedes it. Govinda Dvādaśī, Bhīṣma Dvādaśī, and Vāmana Dvādaśī (Bhādrapada-Śukla) are among the classical named Śukla-Dvādaśīs. The Śukla-Dvādaśī half-tithis carry the movable karaṇas Bava and Bālava, both generally favourable. In Kṛṣṇa-pakṣa, Dvādaśī carries the waning register and the pāraṇa function for the Kṛṣṇa-Ekādaśī vrata. The Kṛṣṇa-Dvādaśī half-tithis carry Kaulava and Taitila, both movable karaṇas. The classical weight of the tithi is equal across the two pakṣas given the vrata-pāraṇa function attaches fortnightly on both sides.
Muhūrta-relevance
Dvādaśī is classically favourable for general auspicious undertakings — travel, formal arrangements, ceremonial work — and specifically required for the Ekādaśī pāraṇa. The classical rule for pāraṇa is that it must be performed on Dvādaśī within a specific window that excludes the first quarter of the tithi in some traditions and requires completion before the tithi ends in others. The tithi is read alongside vāra — Dvādaśī on Bṛhaspativāra (Thursday, Guru's day) carries the classical reinforcement for Vaiṣṇava observance. All movable karaṇas appear in Dvādaśī's window, none of them Viṣṭi/Bhadrā.
