Graha–Ketu–Utpāta Lakṣaṇas: Solar/Lunar Omens, Comets, Eclipses, and Calendar Rules
कृष्णापंचदशी माघे द्वापरादिरुदीरिता । कल्पादिः स्यात्कृष्णपक्षे नभस्यस्य त्रयोदशी ॥ १४८ ॥
kṛṣṇāpaṃcadaśī māghe dvāparādirudīritā | kalpādiḥ syātkṛṣṇapakṣe nabhasyasya trayodaśī || 148 ||
Es wird gelehrt, dass der Beginn des Dvāpara auf die Amāvāsyā (Kṛṣṇā Pañcadaśī) im Monat Māgha fällt; und dass der Anfang eines Kalpa auf den dreizehnten Tithi (Trayodaśī) der dunklen Hälfte im Monat Nabhasya (Bhādrapada) fällt.

It links cosmic cycles (yuga and kalpa) to sacred lunar time (tithi and month), showing that dharmic life and contemplation of liberation are grounded in precise, sanctified time-reckoning.
By emphasizing holy calendrical moments, it supports disciplined observance—choosing auspicious tithis for worship and vows—so devotion becomes steady and aligned with sacred time.
Vedāṅga Jyotiṣa: the practical use of lunar months and tithis (Amāvāsyā, Trayodaśī; Māgha, Nabhasya/Bhādrapada) to mark ritual and cosmological commencements.
