वैशाखस्य तृतीया या शुक्ला त्रेतादिरुच्यते । माघे पञ्चदशीनाम द्वापरादिः स्मृता बुधैः
vaiśākhasya tṛtīyā yā śuklā tretādirucyate | māghe pañcadaśīnāma dvāparādiḥ smṛtā budhaiḥ
Der helle dritte Tithi des Monats Vaiśākha heißt der Beginn des Tretā-Yuga; und die Weisen gedenken des Vollmondtages im Monat Māgha als Beginn des Dvāpara-Yuga.
Lomaharṣaṇa (Sūta), addressing the sages (deduced from Māheśvarakhaṇḍa context)
Tirtha: Yugādi markers: Vaiśākha-śukla-tṛtīyā (Tretāyugādi), Māgha-pūrṇimā (Dvāparayugādi)
Type: kshetra
Scene: Two-panel calendrical vision: (1) Vaiśākha bright third—sunlit riverbank with devotees giving gifts and starting auspicious works; (2) Māgha full moon—moonlit snāna with lamps floating on water; above, a subtle yuga-wheel indicating Tretā and Dvāpara beginnings.
The Purāṇas map cosmic epochs onto sacred calendar days, making specific tithis especially auspicious for merit.
No tīrtha is specified; the glorification is of auspicious tithis (Vaiśākha śukla tṛtīyā; Māgha paurṇimā).
Observance of these tithis as Yugādi times; traditional practice emphasizes charity, worship, and offerings on such days.
