Tṛtīyāतृतीया(Tritiya)
The third tithi; primary devatā Gaurī (Viṣṇu in Kṛṣṇa-3), Jayā-class, classical register of victory-oriented and marital auspiciousness.
Tṛtīyā
Tṛtīyā (तृतीया, also written Tritiya) is the third of the thirty tithis, occurring in both Śukla-pakṣa and Kṛṣṇa-pakṣa. The name means "the third," and classical tradition gives this tithi a particular weight because several major devotional observances fall specifically on Śukla-Tṛtīyā in different lunar months. Its presiding devatā in the primary register is Gaurī — the goddess as Pārvatī in her classical form associated with marital harmony, youth, and protective grace. In the Kṛṣṇa-pakṣa register, some classical sources give Viṣṇu as devatā. In the five-class auspiciousness scheme of the Muhūrta Cintāmaṇi, Tṛtīyā belongs to the Jayā class (tithis 3, 8, 13) — the victory-oriented register.
Classical grounding
Muhūrta Cintāmaṇi and the Nirṇaya Sindhu identify Gaurī as Tṛtīyā's primary devatā. The Skanda Purāṇa and Devī Bhāgavata Purāṇa describe the Gaurī-Tṛtīyā observances in detail, including Hartālikā Tṛtīyā (Bhādrapada-Śukla-Tṛtīyā) and Gaṅgaur (Caitra- Śukla-Tṛtīyā), both observed by women for marital well-being. Some classical muhūrta sources give Viṣṇu as the Kṛṣṇa-Tṛtīyā devatā, recognising the same tithi's different register in the waning fortnight. The Jayā auspiciousness classification places Tṛtīyā among the victory-oriented tithis, suitable for activities where contested outcome is at stake.
Significations
What Tṛtīyā classically governs:
- Marital auspiciousness — the Gaurī association gives the tithi specific weight for marriage-related rituals, particularly observances by women for the well-being of husbands and families
- Victory in contested activities; the Jayā classification applies
- The Akṣaya Tṛtīyā observance on Vaiśākha-Śukla-Tṛtīyā, classically considered the most auspicious day of the year for initiating new ventures — the akṣaya ("imperishable") register names the day as one whose fruits do not diminish
- Charitable giving and dāna observances; Akṣaya Tṛtīyā specifically is classically associated with gold purchase and gift-giving
- Jewellery, ornamentation, and the aesthetic-register work that Gaurī's domain encompasses
- Beginnings of artistic projects where auspicious timing matters
Pakṣa-level reading
In Śukla-pakṣa, Tṛtīyā carries the waxing register and the primary Gaurī devatā attribution — the most auspicious manifestation and the site of the major Tṛtīyā observances (Akṣaya Tṛtīyā, Hartālikā, Gaṅgaur). The Śukla-Tṛtīyā half-tithis carry the movable karaṇas Taitila and Gara. In Kṛṣṇa-pakṣa, Tṛtīyā carries the waning register with Viṣṇu as devatā in some classical readings — the tithi is still Jayā-class and favourable, but oriented toward the completion or resolution of prior commitments rather than toward new initiatives. The Kṛṣṇa-Tṛtīyā half-tithis carry Vaṇij and Viṣṭi — and Viṣṭi (the Bhadrā karaṇa, distinct from the Bhadrā- class tithi naming) is classically avoided for most auspicious work.
Muhūrta-relevance
Tṛtīyā is classically favourable for marriage-related undertakings, for purchase of jewellery and ornaments, for charitable giving (particularly on Akṣaya Tṛtīyā), and for the opening of aesthetic projects. The Kṛṣṇa-pakṣa manifestation carries Viṣṭi (Bhadrā karaṇa) in its second half — this karaṇa is classically avoided for auspicious work, meaning half of every Kṛṣṇa-Tṛtīyā carries muhūrta caution despite the tithi's generally favourable Jayā register.
