Diwali is also known as Deepavali or Deepawali in India. The name of this festival can be translated as "rows of lights or series of lights" or simply the celebration of lights. It is actually a festival of lights. People light small clay lamps known as Diyas in their homes, and even the streets are decorated with lights during the festival day. Other than in India, few other Asian countries also celebrate this festival. You may also find the celebrations elsewhere where the Indian communities reside.
Diwali is a National holiday in many countries where the festival is celebrated.
