Amavasya ke baare mein
Amavasya wo tithi hai jab chandrama dikhai nahi deta — surya aur chandrama ek hi rashi mein hote hain. Yeh din pitru tarpan, shraddh aur daan ke liye maana jata hai.
Uttar Bharat mein amavasya ko agle mahine ke naam se pukara jata hai (purnimanta paddhati), isliye Ashwin ki amavasya ko "Kartik Amavasya" kaha jata hai — Diwali wali raat.
