Triratri Vrata is a three-day Vrat dedicated to Srihari Vishnu and it begins two days before Shukla Paksha Ekadasi or eleventh day of the waxing phase of moon. Triratri Vrata 2024 begins on November 11 and ends on November 12. The greatness of Triratri Vrata was narrated to Narada Rishi by Shiva.
Those observing the Vrata stay awake for three nights, worshipping Srihari Vishnu and Lakshmi with flowers, fruits, water and Tulsi leaves. The belief is that performing this vrata helps one in attaining mastery in arts and science.
The Vrata ends on the Ekadasi day in Shukla Paksha of Kartik month – which is the famous Hari Prabodhini Ekadasi. Tulsi Puja also begins from the day.
