Durga Puja is widely celebrated especially in Eastern parts of India, One of the notable mentions is Bengal, where the festivities take a huge prominence. Puja reaches its full moon within the last four days from Maha-Shashti to the day when the idols take a water dip, which is held on the eve of Dashami. The legend talks about the descent of Goddess to earth on Shashthi. She arrives on the sixth day (shashthi) and leaves on the tenth day (Dashmi). The whole festival is ten day long. The preparation for Durga Puja starts weeks before the actual event where people clean up their houses and adorn them with a welcome sign.
