Diwali is also known as the festival of lights. Diwali is an important festival of the Hindus. It is a five day long festival that starts on Dhanteras and ends on Bhai dooj. It is held on the fifteenth day of Kartik month. People clean their houses before Diwali. In the night people illuminate their houses with rows of small earthen lamps. In big towns people illuminate their houses with electric bulbs instead of earthen lamps. It is the belief of some people that on the night of the Diwali, Goddess Lakshmi, who is the goddess of wealth, pays a visit to each house. She bestows her blessings on the houses which are neat and clean and turns her face against dirty houses. In the night people perform the Puja of the goddess and distribute sweets. In Bengal, Kali Puja is performed on the night of the Diwali.Some people also indulge in gambling on this day. Boys purchase toys and feel very happy. They also purchase paper-lanterns and light lamps in them. Some people make a display of fireworks during Diwali Festival.
