Vijayadashami also known as Dasara, Dashahara, Dussehra, Dashain (in Nepal), Navratri or Durgotsav is one of the most important Hindu festivals celebrated in various forms, across Nepal, India and Bangladesh.
The name Dussehra is derived from Sanskrit Dasha-hara literally means The sun will not rise (Dasha(sun) and Hara(defeat)) referring to Lord Rama’s victory over the ten-headed demon king Ravana. The day also marks the victory of Goddess Durga over the demons Mahishasur. The name Dussehra is also derived from Sanskrit Dasha + Ahaha = Dasharahaha = Dasharaha. Ahaha means day. Example Aharnisha is derived from Ahaha+nisha. Goddess fought with evils for 9 nights and 10 days. The name Vijayadashami is also derived from the Sanskrit words “Vijaya-dashami” literally meaning the victory on the dashami (Dashmi being the tenth lunar day of the Hindu calendar month). Diwali the festival of lights is celebrated twenty days after Dasara.
