Dol Purnima, also known as Dol Jatra, Doul Utsav, or Deul, is one of the most vibrant Hindu festivals celebrated in eastern India. This festival marks the full moon day of the Hindu month of Phalguna (February-March) and coincides with Holi, the famous festival of colors. Dol Purnima is deeply associated with the love and devotion of Lord Krishna and Radha, making it a significant Radha Krishna festival. The event is widely observed in West Bengal, Odisha, Assam, and other parts of India, where devotees engage in various Dol Purnima rituals, including processions, music, and playful throwing of colors.
