The Exposition of the Dvādaśī Vow for the Twelve Months
Dvādaśī-vrata-nirṇaya and Mahā-dvādaśī Lakṣaṇas
यदा तु धवले पक्षे द्वादशी स्यान्मधान्विता । तदा प्रोक्ता जया नाम सर्वशत्रुविनाशिनी ॥ १०५ ॥
yadā tu dhavale pakṣe dvādaśī syānmadhānvitā | tadā proktā jayā nāma sarvaśatruvināśinī || 105 ||
ولكن إذا وقع يوم الدوادشي (اليوم القمري الثاني عشر) في النصف المضيء مقترنًا بشهر مَدْهو (شيترا)، فإن تلك العبادة تُسمّى «جَيا»، وهي التي تُهلك جميع الأعداء.

It defines a specific sacred timing: when Dvādaśī in the bright fortnight coincides with the month Madhu (Caitra), the vrata is called Jayā and is praised for removing hostile forces and obstacles.
By highlighting a named Dvādaśī observance, it points to time-based devotional discipline—keeping a vrata on an auspicious tithi as a supportive practice for Vaiṣṇava devotion and spiritual protection.
It uses calendrical computation—tithi (Dvādaśī), pakṣa (śukla/bright fortnight), and māsa naming (Madhu/Caitra)—which aligns with Jyotiṣa (Vedāṅga astrology) for determining correct ritual timing.
