Triratri Vrata is a three-day Puja during Navratri Durga Puja. In 2018, Triratri Navratri Pooja begins on October 16 and ends on October 18. Usually, it begins on Maha Saptami with Saraswati Avahan and ends with Saraswati Balidan or visarjan on Mahanavami day. As last three days of Navratri are dedicated to Goddess Saraswati, it is also referred to as Saraswati Pujan.
The same rituals of Navratri are followed during Triratri Vrata. Kalasha Sthapana is performed before starting the puja on first day and Kalasha will be moved after the completion of Puja on third day. Those who unable to perform the Navratri Puja for nine days, would prefer Triratri Vrata observance.
