FAQ
What is Amavasya Krishna tithi?
Amavasya is the Krishna Paksha tithi (lunar day) ruled by Pitris, falling in the Rikta category per Bṛhat Saṁhitā Ch 99.
Why is Amavasya avoided for new starts?
Rikta-class tithis (Chaturthi, Navami, Chaturdashi, Amavasya) are universally avoided for foundation laying and griha-pravesha. Use a non-Rikta date instead.
Can the tithi alone decide a muhurta?
No — the pañcāṅga uses five limbs: tithi, vāra (weekday), nakshatra, yoga, karaṇa. A strong tithi must be combined with a favourable nakshatra and karaṇa to be fully auspicious.
