Amavasya, New Moon Days
Amavasya is the new moon day on the Hindu calendar. It is a significant day, as many rituals are performed only on the day of the Amavasya Tithi. Amavasya that falls on Monday is known as Somvati Amavasya and Amavasya falling on weekday Saturday is known as Shani Amavasya. All Amavasya days are appropriate to perform Shraddha rituals to appease ancestors. Amavasya day is also appropriate day to perform Kalasarpa Dosha puja.
