Anant Chaturdashi is a Hindu festival marking the end of the 10-day Ganesh Chaturthi celebration, dedicated to the god Vishnu, specifically his divine serpent form, Ananta (or Shesha). Observed on the 14th day of the waxing moon in the Hindu month of Bhadrapada, devotees venerate Lord Ananta to free themselves from sins, with traditions including wearing a sacred red thread, fasting, and the famous Ganesh Visarjan (immersion of Ganesh idols).
