Question

why is diwali called the festival of light

Answer 1

When Lord Rama returned to Ayodhya after winning the war with Ravana, the people of Ayodhya lit lamps and the city was lit during the night as if it was a day. From then we celebrate diwali by lighting lamps and burning fireworks. This is why it is called the festival of lights.

Answer 2

Diwali is called the festival of light because we burn crackers and light Diyas on that day. we cannot see this much light in any other festival.
